Best Time to Visit Greece — Month by Month
Curated by Our Guild Explorers · Updated August 2026
Greece has a long season and a short peak, and the difference between them is enormous — not only in temperature and price, but in whether a village feels like a place people live or a queue with a view. This guide goes through the year honestly: what the weather actually does, when the sea is warm enough to swim, when the ferries stop being reliable, which islands close altogether, and where the crowds are worst. If you take only one line from it, take this one: late September and early October are the finest fortnight of the Greek year, and almost nobody plans for them.
The short answer
For most travellers, the answer is late April to mid-June or mid-September to late October. Both give you warm, bright days, a sea that is swimmable, everything open, and crowds and prices well below the peak. July and August are hot, expensive and very busy, and the meltemi wind disrupts ferries. November to March is quiet, cheap and often lovely on the mainland — Athens, Delphi, Meteora and Thessaloniki are all rewarding in winter — but most island hotels and restaurants are shut. If you are travelling at an unhurried pace and dislike heat and crowds, aim squarely at the second half of September.
Season by season
Spring — April to early June
The best light of the year and hillsides full of wild flowers. April is variable and can bring rain, with sea temperatures still bracing; by mid-May the days are reliably warm and most island hotels have opened. Early June is close to perfect: hot enough to swim, cool enough to walk around a ruin at noon, and the crowds have not arrived. Greek Orthodox Easter, which usually falls later than the Western date, is the loveliest week to be here and also the busiest for domestic travel — book early if it falls inside your dates.
High summer — mid-June to August
Hot, bright, expensive and crowded. Athens regularly passes 95°F and during heatwaves the Acropolis closes in the middle of the day for safety. The sea is at its warmest and every hotel, restaurant and beach club is open, but the islands are at capacity, the ferries are full and the meltemi wind blows hard for days at a time, cancelling high-speed boats. Mid-August is peak of the peak: the 15 August feast of the Assumption is a national holiday and Greeks travel en masse.
Autumn — September to October
The best-kept secret in Mediterranean travel. September still has hot, settled weather and the sea is at its warmest of the year after a summer of heating, but the crowds thin from the middle of the month and rates fall sharply. October is gentler still — warm days, cool evenings, thin crowds and beautiful light — though by the last week some island hotels begin to close and the first rains arrive. For unhurried travellers, this is the season we recommend above all others.
Winter — November to March
A different country, and a rewarding one if you know what you are getting. The mainland comes into its own: Athens without queues, Delphi and Meteora in low winter light, Thessaloniki’s restaurants at their best, and skiing in the mountains. Crete and Rhodes stay mild and keep their town hotels open all year. But most of the Cyclades effectively close — hotels shuttered, restaurants dark, ferries reduced — so do not plan a winter island holiday around Santorini or Mykonos.
Month by month
Temperatures are rough daytime highs for Athens and the southern islands; the north and the mountains run several degrees cooler.
January — about 55°F
The quietest month. Athens is cool and often bright, with occasional rain and the sites almost empty; museums keep shorter winter hours. Crete is the mildest place in the country. Most Cycladic islands are closed for the season. Excellent value, and a fine time for a city-and-antiquities trip if you do not need a beach.
February — about 57°F
Much like January but with the first hint of spring by month’s end and almond blossom in the south. Carnival (Apokries) brings parades and celebrations, particularly at Patras. Still very quiet, still very cheap, and still the wrong month for the islands.
March — about 62°F
Spring begins in earnest. Wild flowers appear, days lengthen and Athens is delightful for walking. The 25 March national holiday brings parades. A few island hotels open at the end of the month, but ferry schedules are thin and the sea is far too cold for swimming.
April — about 68°F
The countryside is at its greenest and the light is extraordinary. Weather is variable and rain is quite possible, but a warm April week in Greece is hard to better. Many island hotels open around mid-month; the sea is still bracing. If Greek Orthodox Easter falls in April, expect wonderful ceremonies, full hotels and heavy domestic travel.
May — about 76°F
One of the two best months. Reliably warm, everything open, the sea just about swimmable by the end of the month, and the crowds still modest. Ideal for combining Athens with an island, or for walking the Samaria gorge in Crete before the heat arrives.
June — about 84°F
Early June is close to perfect: hot, settled and not yet crowded, with a comfortably warm sea. By the last week the schools break up across Europe and the islands begin to fill. A very good month for a first trip if you can travel in the first half of it.
July — about 91°F
Hot and busy. Beach weather is guaranteed and every restaurant, boat and beach club is running, but sightseeing in the middle of the day becomes hard work and Athens can be genuinely oppressive. The meltemi wind builds through the month, which cools the Cyclades pleasantly but disrupts high-speed ferries.
August — about 92°F
The peak, and the month we would steer most readers away from. Highest temperatures, highest prices, fullest hotels and heaviest crowds, with the 15 August national holiday adding domestic travel on top of international. The sea is at its warmest, which is the compensation. If you must come in August, book everything months ahead and choose a coastal hotel over an inland one.
September — about 85°F
The best month of the year, in our view. The first half still feels like summer with a warm sea; from mid-month the crowds thin noticeably, rates fall and the light softens. Everything remains open. If you have any flexibility at all, spend it here.
October — about 76°F
Gentle, beautiful and inexpensive. Warm days, cool evenings, thin crowds, and a sea still warm enough for a swim in the first half of the month. Some island hotels and beach clubs begin closing from mid-month onwards, and the first serious rains usually arrive at the end. Wonderful for Athens, Crete and Rhodes.
November — about 67°F
The season ends. Most Cycladic hotels have closed and ferry schedules thin out sharply. The mainland, however, is lovely: cool, clear days for Athens, Delphi and Meteora, and very low prices. Crete and Rhodes stay mild and keep their town hotels open.
December — about 59°F
Cool, sometimes wet, and very quiet. Athens does Christmas well, with lights, markets and no queues at the Acropolis. Skiing begins in the mountains. The islands are shut. A good choice for a cheap, unhurried city break rather than a beach holiday.
What is open when
The single most useful thing to understand about timing a Greek holiday.
The islands run a season, not a year
Most hotels, restaurants and beach clubs on Santorini, Mykonos and the smaller Cyclades open around Easter or the start of May and close in late October or early November. Between November and March many islands have only a handful of places open, ferry schedules are thin and the weather can strand you. This is the single most important thing to understand when planning a Greek trip outside summer.
The mainland is open all year
Athens, Delphi, Meteora, Nafplio and Thessaloniki work in every month, and a winter visit to any of them is a real pleasure — no queues at the Acropolis, museums to yourself, and hotel rates a fraction of summer. Sites keep shorter winter opening hours, so check before you set out.
Crete and Rhodes are the year-round islands
Both are large enough to have real towns rather than resorts. The town hotels of Chania, Rethymno, Heraklion and Rhodes Town stay open all year and the climate is the mildest in Greece. The big beach resorts on both islands are still seasonal, closing roughly November to April, so choose a town hotel for a winter visit.
Easter moves, and it matters
Greek Orthodox Easter usually falls on a different date from the Western one, sometimes by several weeks. It is the most important holiday of the Greek year: the ceremonies are beautiful, the food is extraordinary, and the whole country travels. Hotels and ferries fill, and some businesses close for a few days. Wonderful to witness — but book well ahead if your dates overlap.
Heat, wind and crowds — plainly
Summer heat is a health question, not a comfort one
Athens regularly passes 95°F in July and August, and in a heatwave the Acropolis closes during the middle of the day for safety. For anyone with a heart or breathing condition, that is worth planning around rather than enduring. If you travel in high summer, sightsee before ten in the morning and after five in the afternoon, keep the middle of the day for a shaded lunch or a pool, and drink far more water than feels necessary.
The meltemi — a wind with consequences
From roughly July to early September a strong northerly wind blows down the Aegean. It makes the Cyclades pleasantly cool, which is why the islands are bearable in August at all — but it whips up the sea, and high-speed catamarans are cancelled regularly when it blows. Large conventional ferries usually sail regardless and are far steadier. Never plan a same-day ferry connection to a flight in July or August; leave a night’s margin.
Cruise ships set the rhythm on the small islands
On Santorini and at Rhodes Old Town, day visitors arrive in a predictable wave through the late morning, fill the lanes at midday and leave in the late afternoon. Santorini now caps cruise arrivals, but the pattern holds. See the famous places before half past nine in the morning or after six in the evening, and use the middle of the day for lunch, a swim or somewhere the ships do not reach.
Prices move more than the weather does
The gap between an August rate and a late-September rate on the same room is often a third and sometimes a half. Flights follow the same curve. Shifting a Greek holiday two or three weeks later in the year buys warmer sea, thinner crowds, softer light and a materially smaller bill — which is why we keep pointing at the same fortnight.

Common questions about timing a Greek trip
What is the overall best time to visit Greece?
Late April to mid-June and mid-September to late October. Both give warm, bright days, a swimmable sea, everything open, and crowds and prices well below the peak. If we had to choose a single fortnight, it would be the second half of September: the sea is at its warmest after a summer of heating, the crowds have thinned, the light has softened and rates have fallen sharply from August.
Is Greece too hot in July and August?
For sightseeing, often yes. Athens regularly passes 95 degrees Fahrenheit, and during heatwaves the Acropolis closes in the middle of the day for safety, which is worth taking seriously if you have a heart or breathing condition. The islands are cooler thanks to the meltemi wind, and the sea is at its warmest. If you must travel then, sightsee early and late, keep the middle of the day for shade or a pool, and choose a coastal hotel over an inland one.
Which Greek islands are open in winter?
Crete and Rhodes are the reliable ones: both are large enough to have real towns, and the town hotels in Chania, Rethymno, Heraklion and Rhodes Town stay open all year with the mildest climate in Greece. Corfu also keeps some hotels open. Most of the Cyclades, including Santorini and Mykonos, effectively close from November to March, with only a handful of places trading and thin ferry schedules. Do not plan a winter island holiday around them.
When is the sea warm enough to swim in Greece?
Broadly June to early October. May is bracing for most people, June is comfortable, July through September is genuinely warm, and the sea is at its warmest in late August and September after a whole summer of heating. The first half of October is still pleasant for a swim in the south; by November it is cold. Northern Greece runs a little cooler than Crete and the Dodecanese throughout.
What is the meltemi wind, and will it affect my trip?
It is a strong northerly wind that blows down the Aegean from roughly July to early September. It keeps the Cyclades bearable in high summer, but it whips up the sea, and high-speed catamaran ferries are cancelled regularly when it is blowing. Large conventional ferries usually sail through it and are far steadier. The practical advice is simple: in July and August, never plan a same-day ferry connection to a flight home — leave a night’s margin in Athens.
When should I visit Santorini to avoid the crowds?
Late April to early June, or mid-September to late October. Even within a peak-season day the crowding is predictable: cruise passengers come up the cable car mostly between about half past nine and noon, fill Fira and Oia through midday, and queue to go back down between half past three and six. See Oia before half past nine in the morning or after six in the evening, whatever month you travel, and the village becomes a genuinely different place.
Is it worth visiting Greece in winter?
On the mainland, very much so. Athens without queues, Delphi and Meteora in clear winter light, Nafplio out of season and Thessaloniki’s restaurants at their best make a rewarding and inexpensive trip, and there is skiing in the mountains. Sites keep shorter winter hours, so check before setting out, and pack for cool, sometimes wet weather. For an island beach holiday, though, winter is the wrong season — almost everything is closed.
