Where to go in each season
Greece is not one climate. The Aegean islands are dry and windy, the Ionian is greener and wetter, Crete has the longest season, and the north and mountains run cooler all year.
May–June and September to early October are the sweet spot across the country: warm sea, open islands and fewer crowds than July–August. Winter suits Athens, Thessaloniki and the mainland, not island-hopping.
| Region | Best months | Notes |
|---|---|---|
| Athens and Attica | April–May, September–October | Dry and sunny; July–August often over 35 °C with heatwaves to 40 °C+; winters mild with rain |
| Cyclades and Dodecanese | May–June, September | Windy: the meltemi blows hardest July–August and cancels small boats; sea warm enough June–October |
| Crete | April–June, September–October | Longest season: sea swimmable into November on the south coast; White Mountains keep snow into spring |
| Ionian islands and west | May–June, September | Greener and wetter than the Aegean; less wind, calm seas in summer |
| North and mountains | May–June, September–October | Cold winters with snow in the mountains; Zagori and Pelion are cooler escapes in summer |
Cost and crowds by season
Peak season in Greece is roughly mid-June to early September, with a second spike around 15 August when Greeks take their own holidays. In those weeks, island rooms and ferries sell out and prices are at their highest. Shoulder months give you the same sea with more space and lower rates.
Winter is the cheapest time, but you get a different trip: Athens and Thessaloniki stay open and cheap, while most island hotels, tavernas and seasonal ferries shut. If your plan is island-hopping, winter is the wrong season, not just a quiet one.
For a full breakdown of daily costs, see the cost of travel in Greece page.
- Book ferries and island rooms early for Orthodox Easter, July, August and the 15 August peak.
- Late June and early September often cost less than the weeks between them.
- April and October are good value on the mainland, with some island businesses still closed.
Events that change your dates
Greek holidays move demand more than the weather does. Orthodox Easter is the biggest: ferries and rooms fill weeks ahead, and island towns are busy with visitors returning home. Clean Monday starts Lent with kite-flying and seafood, and 25 March brings Independence Day parades in Athens and every town.
Carnival (Apokries) in February peaks in Patras. In summer, local panigyria festivals fill village squares, and the 15 August Assumption is the busiest travel weekend of the year. Check dates before booking, since Easter moves each year.
| Date | Event | Effect on travel |
|---|---|---|
| 1 January | New Year's Day | Quiet; many businesses closed |
| 6 January | Epiphany | Harbour ceremonies; minor disruption |
| February (moves) | Carnival / Apokries | Patras parade; book ahead |
| March (moves) | Clean Monday | Offices closed; seafood and kite-flying |
| 25 March | Independence Day | Parades in Athens and towns |
| April 2026 / May 2027 | Orthodox Easter | Ferries and rooms fill fast; book early |
| 15 August | Assumption | Busiest travel weekend; ferries sold out |
| 17 November | Anniversary marches | Central Athens traffic and closures |
| 25–26 December | Christmas | Mainland festive; islands closed |
Dates for moving holidays differ each year.
Practical notes
Summer heat is the main risk. In July and August, sightseeing is best before 11am and after 6pm, with a long midday break. Carry water, use sun protection and watch for heat exhaustion. Wildfire risk is highest in those months, so follow local advisories and never light fires outdoors.
The meltemi wind is a summer feature of the Aegean. It cools the islands but can cancel small boats and ferries, so build slack into tight island-hopping plans. Winter rain is heaviest in the west and on the islands; Athens and the east stay drier.
Before you book, check entry rules on the visa requirements page and safety notes on the is Greece safe to visit page.
How to choose your dates
Start with what you want to do. Beaches and swimming: aim for June or September. Sightseeing and hiking: April, May or October. A city break: any month, with Athens and Thessaloniki at their best in spring and autumn.
Then match the region. If your dates fall in April or late October, pick Crete or Rhodes over the Cyclades, since they stay open longer. If you must travel in July or August, choose one or two islands and book ferries and rooms well ahead.
- Beach trip: June or September.
- Sightseeing and hiking: April, May or October.
- City break: any month; spring and autumn are best.
- Tight dates in April or late October: choose Crete or Rhodes.
- Peak-summer trip: fewer islands, earlier bookings.

Questions people ask
What is the best time of year to visit Greece?
May–June and September to early October. You get a warm sea, open islands and fewer crowds than July–August. Late April and October suit mainland sightseeing, while November to March is best kept to Athens, Thessaloniki and the mainland.
When is the cheapest time to visit Greece?
November to March is cheapest, but most island hotels and seasonal ferries are closed. For an island trip at lower prices, aim for late April, May or October, and avoid Orthodox Easter, July, August and the 15 August peak.
What is the weather like in Greece each month?
January–March is cool and wet, mild in Athens. April–May warms up with wildflowers and good walking. June–August is hot, often above 35 °C in Athens, with the meltemi wind in the Aegean. September–October stays warm and swimmable, especially in Crete and Rhodes. November–December turns rainy and quiet.
Is July or August too hot for Greece?
It can be. Athens often passes 35 °C and heatwaves reach 40 °C+. Sightsee early and late, rest at midday, and pick islands with a breeze. Wildfire risk is highest then, so follow local advisories.
When is the sea warm enough to swim?
Roughly June to October in the Aegean and Ionian, with September the warmest month. Crete and Rhodes can stay swimmable into November on the south coast. In May the sea is cool but some travellers swim late in the month.
Should I avoid the Greek islands in winter?
For island-hopping, yes: most hotels, tavernas and seasonal ferries shut from November to March. Athens, Thessaloniki, Meteora and the mainland stay open and cheap, so winter suits a city and mainland trip instead.
