Best Time to Visit Greece 2027, Month-by-Month for Aussies

News & AdviceGuide

20 Nov

Updated September 2026

September. Every time. That is the answer my family lands on, and has landed on for about forty years of going back, and the reason is the sea. The water in September has been warming since May and it holds that heat like a stone wall at dusk. Nobody swims in Greece in May the way they swim in Greece in September.

But you are not my family, and you may be locked to school holidays, or a fare sale, or three weeks of leave your boss signed off in February. So here is the whole year, month by month, with what the weather does, what the crowds do, what it costs, and what closes. Planning the bigger trip? Start with our guide to travelling to Greece from Australia, then come back here to pick your dates.

Best time to visit Greece, the quick answer

The best time to visit Greece is late May or September. Both give you warm weather, swimmable water, open islands and prices below the July and August peak. September has the warmer sea (24 to 25°C) and suits Australian spring school holidays. May has wildflowers, greener hills and better value. Avoid August unless heat and crowds are the point.

Greece month by month at a glance

Air temperatures are Athens averages. The islands run a touch cooler in summer thanks to the wind, and the far north runs colder in winter.

January. 8 to 15°C air, 15°C sea. Wet, short days, most islands shut. Cheapest flights of the year. Good for Athens, Meteora and skiing.
February. 8 to 15°C air, 15°C sea. Still winter. Carnival season and the most reliable snow at Parnassos.
March. 10 to 16°C air, 15 to 16°C sea. Wildflowers, hiking, Independence Day. Islands still mostly closed.
April. 15 to 20°C air, 16 to 18°C sea. Sightseeing weather. Islands start opening. Easter timing matters enormously.
May. 20 to 25°C air, 19 to 20°C sea. Everything open, nothing overrun. One of the two best months.
June. 25 to 30°C air, 21 to 23°C sea. Long days, full summer, prices already high.
July. 28 to 35°C air, 24 to 25°C sea. Peak heat, peak ferries, peak meltemi wind.
August. 28 to 36°C air, 25 to 26°C sea. The most expensive and most crowded month. Warmest water.
September. 24 to 30°C air, 24 to 25°C sea. Warm sea, thinning crowds, falling prices after the 15th.
October. 18 to 25°C air, 21 to 23°C sea. Lovely and quiet, but small islands close from about the 20th.
November. 15 to 20°C air, 19°C sea. Rain returns. Athens and the mainland only.
December. 10 to 15°C air, 16°C sea. Cold, wet, cheap. Ski season opens if the snow arrives.

How Greece's climate works

Greece is several climates wearing one flag. Corfu on the west coast gets nearly twice the annual rainfall of Naxos in the middle of the Aegean. Thessaloniki in the north gets frost. Crete in the south gets Februaries you can sit outside in. When someone tells you "Greek weather in April," ask them which Greece.

The broad shape is Mediterranean: hot dry summers, mild wet winters. Mild is doing some work in that sentence. Athens in January sits around 10°C, which sounds fine until you learn that a lot of Greek apartments are built to shed heat rather than hold it, with marble floors and no insulation to speak of. Bring a jumper for indoors. I am not joking.

Tourist season runs roughly May to September, with July and August as the crush. The shoulder months either side of that crush, April to May and September to October, are where the weather and the crowd numbers cross over in your favour. Winter has its own case, which I make below.

One factor most guides skip entirely, and it will affect your ferries: the meltemi, a dry northerly wind that blows down the Aegean mainly in July and August. It is why the Cyclades feel bearable in 34°C heat. It is also why your Mykonos to Naxos sailing gets cancelled at 7am with no warning. More on that in the July section.

January in Greece, quiet, cold and cheap

Weather. 8 to 15°C in Athens, colder in the north, wet, dark by 5.30pm. The Aegean islands get wind and grey water.

Crowds. None. Most island hotels and tavernas are shut until Easter.

Why you'd go. You want Athens without the queue at the Acropolis. You want Meteora or Nafplio or the Zagori villages in the cold, which is when they look best. You want the cheapest fare of the year out of Sydney or Melbourne.

Why you wouldn't. No swimming, reduced ferries, and a lot of closed doors.

From Australia. January is peak summer at home, so you are swapping 35°C for 12°C and a 24-hour flight. Fares drop hard after the first week of January.

What to know. Epiphany falls on 6 January, when priests bless the water at harbours around the country and young men dive in after a thrown cross. It is freezing and they do it anyway. The other January story is snow: the Parnassos resort above Arachova, two and a half hours from Athens, runs December to March, and we have written a full guide to skiing in Greece if that idea appeals. Ski at 10am, eat grilled octopus by the water at 4pm.

February in Greece, carnival and snow

Weather. Much like January, 8 to 15°C, with the days lengthening a little by month's end.

Crowds. Minimal, apart from Patras during carnival.

Why you'd go. Apokries, the Greek carnival season in the weeks before Lent, and the best snow of the year in the mountains. Accommodation is at its floor.

Why you wouldn't. Same as January. Cold, closed islands, no beach.

From Australia. Autumn at home, so the shift is gentler. Fares stay low. If you have no school holidays to work around, February saves you serious money.

What to know. Patras runs one of the largest carnivals in Europe: floats, costumes, a chocolate war, thousands of people in the street behaving in a way that will surprise anyone whose mental image of Greece is a whitewashed chapel. Carnival dates move with Orthodox Easter, so check the calendar before booking. In 2027, Orthodox Easter is late (2 May), which pushes carnival into mid-March.

March in Greece, when the country wakes up

Weather. 10 to 16°C, easing upward through the month. Still rain, but less of it.

Crowds. Low. Domestic travel picks up around Independence Day.

Why you'd go. Hiking before the heat, and wildflowers. The wildflower thing sounds like filler until you see a Naxos hillside in late March covered in poppies and wild chamomile.

Why you wouldn't. Swimming is out. Many islands remain shut until April or May. Weather is a coin toss.

From Australia. Autumn here, spring there. Fares still reasonable before the European season loads up.

What to know. 25 March is Independence Day, with military parades in Athens and school parades in every village. Shops shut. It is also the Feast of the Annunciation, so it carries a religious weight alongside the flags.

April in Greece, when spring arrives

Weather. 15 to 20°C, more sun than rain, warm in the afternoon and cool at night. Sea at 16 to 18°C, which is cold, though you will see a few people in it.

Crowds. Moderate and building. European short-break travellers arrive.

Why you'd go. The best sightseeing weather of the year. You can walk Athens end to end without needing a lie-down. Islands are opening, staff are fresh, prices have not peaked.

Why you wouldn't. Cold water, and Easter can scramble your logistics.

From Australia. Fares climb through April as European spring break hits. Still cheaper than June.

What to know. Orthodox Easter is the biggest event in the Greek year, and it moves. In 2026 it fell on 12 April. In 2027 it falls on 2 May, five weeks after Western Easter, so an April 2027 trip misses Holy Week entirely. That is either a relief or a loss depending on what you came for. If you want to be there for it, read our day-by-day Holy Week schedule first, because ferries thin out, shops close from Good Friday to Easter Monday, and every Greek in the country is travelling to their village at the same time as you.

Cycladic Spaces tip: if your dates land on Holy Week, do not fight it. Pick one town, stay put, and go to the Friday night Epitaphios procession. You will get more out of one village on Good Friday than five islands in a fortnight.

May in Greece, the shoulder season everyone recommends

Weather. 20 to 25°C, sunny, barely any rain. Sea hits 19 to 20°C, which most Australians will swim in without comment.

Crowds. Rising but civilised. Late May is noticeably busier than early May.

Why you'd go. The balance is as good as it gets. Warm enough to swim, cool enough to walk around a site at midday, everything open, prices below summer.

Why you wouldn't. If you want guaranteed 30°C beach days, May can still hand you a cool, windy afternoon.

From Australia. Our late autumn, so you are flying out of the cold into the warm. No Australian school holidays fall in May, which makes it excellent for couples and anyone travelling without kids, and it keeps fares down.

What to know. The light in May is the thing people remember. Sharper than summer, without the white haze that settles over the Aegean in August. If you are island hopping, May is the month the ferry timetables expand to full summer frequency, so the awkward three-day gaps between small islands disappear. Our 10-day Greek islands itinerary is built around exactly this window.

June in Greece, summer without the worst of it

Weather. 25 to 30°C, reliable sun, sea at 21 to 23°C. Long days, sunset near 9pm.

Crowds. High. Europeans who know better than to come in August come in June.

Why you'd go. Full summer Greece with a fraction more breathing room. Everything is open and running, the water is warm, the nights are long.

Why you wouldn't. Summer pricing has arrived. Athens is hot enough that midday at the Acropolis becomes an endurance event.

From Australia. Our winter. Australian school holidays start late June, so families get pushed toward the expensive end of the month.

What to know. The Athens Epidaurus Festival opens in June, with ancient drama staged in the Epidaurus theatre and music at the Odeon of Herodes Atticus under the Acropolis. Check the programme on Visit Greece, the official tourism board, before you set your dates. Athens also moves outdoors in June, and the coast south of the city fills up at night: see our guide to summer nightlife on the Athens Riviera.

July in Greece, heat, crowds and the meltemi

Weather. 28 to 35°C, cloudless, sea at 24 to 25°C. Athens is punishing between 11am and 5pm.

Crowds. Peak. Ferries full, beaches full, Santorini and Mykonos beyond full.

Why you'd go. Guaranteed heat, guaranteed swimming, and Australian winter school holidays that leave you no choice.

Why you wouldn't. Prices at their yearly high and queues at everything worth seeing.

From Australia. Winter here, so the temperature swing is about 25 degrees in the wrong direction for your body clock. Give yourself two days in Athens before you attempt a ferry.

What to know. The meltemi is the July story nobody tells you. It is a dry northerly that funnels down the Aegean and can blow for three or four days without let-up, sometimes longer. It keeps the Cyclades cooler than the mainland, which is a gift. It also cancels ferries. Blue Star Ferries handles it better than the fast catamarans because the big conventional ships can sail in swells that ground Seajets. If your dates are tight and you have a flight home to make, book the slow ferry and build in a buffer day. Our guide to Greek ferry companies covers which operator runs what.

Cycladic Spaces tip: swap Santorini for Sifnos, Folegandros or Milos in July. Same light, same water, a third of the people, and the food is better. I have written at length about why I steer people away from Santorini and Mykonos, and July is the month that argument is strongest.

August in Greece, maximum everything

Weather. 28 to 36°C, relentless, sea at 25 to 26°C. The warmest water of the year.

Crowds. The peak of the peak. All of Europe is on holiday and most of Greece is on an island.

Why you'd go. You want the full summer noise, the beach clubs, the midnight dinners, the 4am walk home. Or August is the only leave you can get.

Why you wouldn't. It is the most expensive month in Greece by a clear margin, and the heat makes archaeology a bad idea before six in the evening.

From Australia. Winter at home, European peak abroad, which is the worst combination for airfares. If you are tied to Australian winter school holidays, late July beats mid-August on both price and sanity.

What to know. 15 August is the Feast of the Assumption, the biggest religious holiday of the Greek summer, and the whole country moves. Ferries sell out weeks ahead. Tinos fills with pilgrims. In Greek-Australian houses, that date means the phone starts ringing at six in the morning because every Maria and every Panagiotis has a name day, and you ring them all. If you are in Greece for it, go to a village panigyri, the saint's day festival, and stay for the dancing.

The other August upside: the August full moon, when the Ministry of Culture opens archaeological sites and museums across the country for free evening visits. Standing at a site at 10pm in August is a different experience to standing at the same site at 10am. Check the Greek National Tourism Organisation for which sites are taking part.

September in Greece, the month Greeks keep for themselves

Weather. 24 to 30°C, sunny, sea at 24 to 25°C. The best all-round conditions of the year.

Crowds. Heavy in the first fortnight, then falling away fast. After about the 15th it changes character completely.

Why you'd go. The water is at its warmest, the heat has stepped back, prices drop mid-month, and the people serving you have stopped wanting to lie down.

Why you wouldn't. Early September still carries August pricing. Late September starts to see closures on the smallest islands.

From Australia. Spring here. Australian spring school holidays land in the back half of September, which is the single best overlap in the calendar for Aussie families. Fares fall once the European summer ends.

What to know. Ask a Greek when to come and a lot of them will say September, then look slightly annoyed that they told you. The sea has had four months of sun in it. The meltemi has usually eased. Restaurant owners have time for a conversation. You can get a table at eight without booking. The vine harvest also starts, and if you like wine, our guide to harvest season in Greece is the companion piece to this one.

October in Greece, the long soft ending

Weather. 18 to 25°C, mostly sunny with rain returning late in the month. Sea holds 21 to 23°C and stays swimmable for anyone who grew up on an Australian beach.

Crowds. Low, and lower every week.

Why you'd go. Cheap, calm and warm enough. Athens in October is close to perfect for walking, and the light through the olive trees on the mainland in late October is worth the trip on its own.

Why you wouldn't. Smaller islands start closing around 20 October. Ferry frequency drops. Some days are windy and grey.

From Australia. Our late spring. No school holidays in the way, fares are moderate, and you get home before the Christmas rush on flights.

What to know. 28 October is Ohi Day, marking Greece's refusal of Mussolini's 1940 ultimatum, with parades and closed shops. Plan island time for the first half of the month and mainland or Athens time for the second half. Crete, Rhodes and Corfu run year-round, so they are the safe October islands if your dates are late. Check current opening seasons and entry requirements on Smartraveller's Greece page before you commit.

November in Greece, when the islands shut

Weather. 15 to 20°C, rain, short days. Sea at 19°C and nobody in it.

Crowds. None outside the cities.

Why you'd go. Athens and Thessaloniki at their most livable, museums empty, prices at the bottom, and a version of Greek life with no tourism layer over the top of it.

Why you wouldn't. The islands are closed. That is most of what people come for.

From Australia. Late spring at home, so you are flying into worse weather than you left. It takes a specific kind of trip to justify that.

What to know. Athens in November smells like roasting chestnuts and wet stone. The Acropolis Museum on a wet Tuesday with fourteen other people in it is one of the better experiences available in Europe, and our Athens museums guide will fill a week. Book somewhere with heating and check the reviews for it specifically.

December in Greece, winter and the start of ski season

Weather. 10 to 15°C, wet, dark early, occasional storms. Sea down to 16°C.

Crowds. None, with a small lift in Athens over Christmas and New Year.

Why you'd go. Greek Christmas, cheap everything, and the opening of the ski season if the snow has come.

Why you wouldn't. Cold, closed islands, reduced hours at archaeological sites.

From Australia. Our summer, so the inversion is total. Fares are decent until about 10 December, then they are not.

What to know. Greek Christmas is a quieter, more domestic affair than the Australian version. Fewer markets, fewer lights, more people in kitchens. New Year's Eve is the bigger night, and the vasilopita, the cake with a coin baked into it, gets cut at midnight. Arachova, the stone town below Parnassos, is the closest Greece gets to an alpine village and it is busy every December weekend with Athenians.

Greece in May or September, which one wins

These two months take up most of the oxygen in any "best time to visit Greece" conversation, and they are not interchangeable. Here is where each one wins.

Sea temperature. September, comfortably. 24 to 25°C against 19 to 20°C. If swimming is the point of the trip, this decides it on its own.
Air temperature. September is warmer and steadier. May will give you the occasional cool, windy day.
Crowds. A draw that depends on timing. Early May is quieter than early September. Late September is quieter than late May.
Price. May, especially the first three weeks. September carries summer pricing until about the 15th.
Landscape. May. Green hills, wildflowers, full rivers. By September the mainland is gold and dry, which is beautiful in a different register.
Service and mood. May staff are fresh and enthusiastic. September staff are tired but relieved, and far more likely to sit down and talk to you.
Australian school holidays. September, and it is not close. Late September spring holidays line up almost perfectly.
Ferry reliability. A draw. Both sit outside the worst of the meltemi.

Short version: book May if you want value and green hills, book September if you want the water. Two different holidays wearing the same weather.

The cheapest time to visit Greece

Winter is cheapest, and the trade is that a lot of Greece is shut. Approximate return economy airfares from the east coast of Australia, which move constantly, so treat these as shape rather than gospel.

Absolute cheapest, January and February. Flights around $1,200 to $1,800. Accommodation 50 to 70 percent below summer. Most islands closed.
Cheap with a functioning country, November and early December. Flights $1,400 to $2,000. Accommodation 40 to 60 percent below peak. Athens and the mainland run normally.
Budget shoulder, late October and early April. Flights $1,600 to $2,200. Accommodation 30 to 40 percent below peak. Weather unpredictable, island services patchy.
Cheapest month with summer weather, early May or late September. Flights $1,800 to $2,400. Accommodation 20 to 30 percent below peak. This is the value pick for most people.

What drives the summer premium: accommodation doubles or triples in July and August, ferry fares rise 30 to 40 percent, car hire runs about 50 percent above shoulder rates, and airfares out of Australia peak because they are competing with the entire European holiday market. For the full numbers in Australian dollars, we have a Greece trip cost breakdown that does the arithmetic in Australian dollars.

Four things that move the needle more than anything else: book flights three to four months out, pick a less famous island (Sifnos over Santorini saves about 40 percent on a bed), eat one street back from the water, and travel in the first half of May or the second half of September.

So when should you go

Match the month to what you came for.

Best weather and fewest compromises. Late May or the second half of September.
Tied to school holidays. Late September for spring, late June or early July for winter holidays. Avoid mid-August.
Warmest possible swimming. August, then September. September gives you the same water with half the people.
Lowest cost. January and February, if you are content with Athens, the mainland and the mountains.
Island hopping. June or September. Full ferry timetables, manageable crowds, less wind than July.
Culture and festivals. Easter (2 May in 2027), Carnival in February or March, and the Athens Epidaurus Festival from June.

Get the month right and the rest of the trip mostly builds itself. Get it wrong and you will spend a fortnight queueing in 36°C heat for a beach that was better in May.

Before you lock anything in, two checks: Visit Greece for festival and event dates, and Smartraveller for entry rules, which have been moving for Australians as the new EU border systems come in. Our explainer on ETIAS for Greece covers what that means for an Australian passport.

Best time to visit Greece FAQs

What is the best month to visit Greece?
May and September. May brings wildflowers, green landscapes and better prices. September brings the warmest sea of the year (24 to 25°C), thinning crowds and Australian spring school holidays. If you only get one pick and you want to swim, take September.

When is the cheapest time to visit Greece?
January and February, when flights from Australia run $1,200 to $1,800 return and accommodation drops 50 to 70 percent. The catch is that most islands close. For low prices with a country that is still operating, try early May or late September.

Is Greece too hot in summer?
July and August reach 28 to 36°C, and Athens is difficult between 11am and 5pm. The islands are more bearable because of the meltemi wind off the Aegean. If you are heat-sensitive, take May, June or September instead.

Can you swim in Greece in May?
Yes. The sea sits around 19 to 20°C, which reads cold on paper and feels fine to most Australians. By the last week of May it is comfortable for almost everyone.

When is the rainy season in Greece?
November through March, with December and January the wettest. October and April get occasional rain. May to September is close to dry, particularly in the Cyclades.

When do the Greek islands close for winter?
Smaller islands wind down from about 20 October and reopen around Easter. Crete, Rhodes and Corfu run all year. Athens and the mainland never close.

Is Greek Easter a good time to visit?
For atmosphere, nothing beats it. For logistics, it is the hardest week of the year. Shops close from Good Friday to Easter Monday, ferries run reduced timetables, and the entire country is travelling. Orthodox Easter falls on 2 May in 2027. Book months ahead and stay in one place.

What is the meltemi?
A dry northerly wind that blows down the Aegean, strongest in July and August. It cools the islands and cancels ferries, sometimes for two or three days running. Conventional ferries cope with it better than fast catamarans, so book the slow boat if your dates are tight.

Can you ski in Greece?
Yes. Parnassos, above Arachova and two and a half hours from Athens, runs December to March, with February the most reliable for snow. Lift passes cost a fraction of the Alps.

When is Greece least crowded?
November to March, though island services largely shut. For quiet weather you can still use, take the second half of October or the first half of April.

What should I pack for Greece in spring?
Layers. March to May swings between 12 and 25°C in a single day. Light jacket, long pants for evenings, shorts and t-shirts for afternoons, walking shoes, sunscreen and a hat from late April, and a packable rain jacket for early spring.

What is the best month for the Greek islands?
May or September for most of them. June if you want guaranteed heat. October is beautiful but the small islands start closing mid-month. The Ionian islands run wetter and greener than the Cyclades, so they hold up better in spring.
