Climate and weather in Greece 2026: by month, by region and where it is warmest in winter

The climate in Greece: Mediterranean, but not uniform

If you had to describe the climate of Greece in one word, it would be Mediterranean: hot dry summers and a mild, relatively wet winter. For most of the year the sun stands over the country, and the rain comes in short, intense bursts in autumn and winter, rather than the dreary all-day drizzle of Northern Europe. This is exactly why Greece appeals both to tourists and to those seeking a Greek climate to live in — in retirement or while working remotely.

But behind that broad label hides a great deal of variation. Greece stretches almost 800 kilometres from north to south; it has plains, high mountains approaching 2,900 metres, and hundreds of islands across three seas — the Aegean, the Ionian and the Mediterranean. Because of this, one and the same January in the southern Cretan town of Ierapetra and in a northern mountain village are two different worlds: in the south it is +18 and palm trees, in the mountains snow and ski slopes.

Broadly speaking, the country’s climate divides into three zones:

• The Mediterranean zone — coasts and islands: a mild winter, hot dry summers and minimal frost. This includes Crete, Rhodes, the Cyclades, the Ionian islands and the coast of the Peloponnese.
• The continental zone — the north and the interior of the mainland (Macedonia, Thrace, the mountain regions): colder in winter, with snow, and a hot but drier summer.
• The mountain (alpine) zone — the Pindus range and the highlands: a real winter with snow and a cool summer.

Below we go through each zone and each season in turn — so that you know exactly what climate awaits you in a given place and month.

Weather in Greece by month: winter (December–February)

Winter is the most underrated season in Greece. In the south it is not winter as we know it, but rather a cool, damp autumn; in the north it is a full-blown cold season. Let us go through the weather in Greece month by month across the winter.

• December. On the coasts and islands it is +14...+17 during the day and around +9...+11 at night. In the north and in Athens it is cooler — +10...+14 during the day. There is rain, but between showers come clear, sunny days. In the mountains snow settles and the ski season opens.
• January — the coldest month. In Athens the average temperature is around +10, in Thessaloniki in the north around +6. On Crete and Rhodes it is still +15...+18 during the day, with frost almost never reaching the southern coast. In the mountains it stays below zero, with snow.
• February — similar to January, but by the end of the month the approach of spring is already felt in the south and the almond trees begin to blossom. Daytime temperatures are +15...+17 on the islands and +10...+13 on the mainland.

The key point about the Greek winter: it is a rainy season, but not a cold one — at least in the south. In terms of temperature, winter on the Greek islands is closer to our September than to December. That said, heating in southern homes is often weak, the houses were built for heat, and the damp chill of +12 in an unheated apartment feels colder than the thermometer suggests. This matters for anyone planning to overwinter here. We cover overwintering in detail in our guide to living on Crete year-round.

Weather by month: spring (March–May) — the best season

Spring is one of the two best seasons in Greece, both for travel and for living. Nature wakes up, everything blossoms, the crowds of tourists have not yet arrived, prices are lower and the weather is already mild and sunny.

• March. A transitional month: +15...+18 during the day in the south, +13...+15 on the mainland. There is still some rain, but more and more sun. The sea is still too cold for swimming (around +15...+16).
• April. True spring: +18...+22 during the day, blossom, greenery, clear skies. The ideal time for exploring ancient sites and going on walks — not hot. In the south, the bold already open the swimming season.
• May. Almost summer: +24...+29 during the day, the sea warming to +19...+21 and comfortable swimming already possible in the south. Tourists are still few and the meltemi (the summer wind) has not yet picked up.

For anyone weighing up the Greek climate as a place to live, spring shows the country at its best: warm but not exhausting, sunny, everything green. Temperatures in May and June usually stay in the +21...+29 range — comfortable for strolling around Athens, for sightseeing and for the first swims of the year. If you are deciding when to visit Greece for the first time — to see the country rather than roast on the beach — May is close to ideal.

Weather by month: summer (June–August) — heat and dryness

Summer in Greece is a classic Mediterranean scorcher: hot, dry, almost no rain, and sun from early morning to late evening. But even here there are regional nuances.

• June. The start of high season: +28...+32 during the day, the sea at +22...+24. The heat has not yet peaked and humidity is low — one of the most pleasant summer months. The meltemi begins to blow across the islands of the Aegean.
• July — the hottest month. On the islands it is +28...+32, but in Athens, because of the urban sprawl and the basin, it is regularly +35...+38 and sometimes close to +40. Athens in summer is the hottest capital in Europe.
• August. Just as hot as July, but the sea is at its warmest of the year (+24...+26). The main month for a beach holiday, but also the most crowded and expensive.

Separately on meltemi — a dry northerly wind that blows across the islands of the Aegean (the Cyclades, the Dodecanese) from mid-June through September, strongest in July and August. It plays a double role: on the one hand it takes the edge off the heat and rescues Santorini and Mykonos when Athens is gasping; on the other it can whip up the sea, cancel ferries and ruin a beach day on the windward side. It is also a serious factor for anyone who sails.

a caveat: summer heat in Greece is intensifying. In July 2024 the country endured the longest heatwave in its history — 16 days, in places two weeks straight above +40. If you cope badly with heat, July and August on the mainland are not the best choice, either for a holiday or for living.

Weather by month: autumn (September–November) — the shoulder season

Autumn is the second ideal season, beloved by those who know Greece. The heat subsides, the sea stays warm, the crowds disperse and the air fills with a soft golden light. This is the famed shoulder season.

• September. The best month of the year on balance of all factors: +26...+30 during the day, the sea warmer than in June (+24...+25), the meltemi easing and fewer tourists. Ideal for both the beach and sightseeing.
• October. Gentle warmth: +22...+25 in the south, the sea still fit for swimming (+22...+23). In the north it is cooler, and the first rains begin. A wonderful time for walks and sightseeing.
• November. The transition to winter: +17...+20 in the south, +13...+16 on the mainland. Rain becomes more frequent, but there are still plenty of sunny days. It is already too cool to swim everywhere except the far south of Crete.

For living and longer stays, September and October are perhaps the best months of the year: the heat has gone, the sea is still warm, prices have fallen, and the island or city belongs to the locals again. If you are deciding when to visit Greece to combine the beach with comfort and no crowds, September is the month to aim for. More on seasonality for the traveller in our guide to Greece.

Where it is warmest in Greece in winter: Crete, Rhodes and the south

This is perhaps the key question for those who want not a week’s holiday but to spend a whole winter in Greece — or to move for good. The answer is unequivocal: the further south, the warmer. The warmest places in winter are the south of Crete, Rhodes and the other islands of the Dodecanese.

Southern Crete — the outright leader. Thanks to its extreme southern position and the shelter the mountains provide from northerly winds, the southern coast of the island holds +16...+20 in winter even in December, January and February. The town of Ierapetra in the south of Crete is considered the warmest in Greece — frost is virtually unknown there, and the winter is more like a cool summer. Crete overall is recognised as the island with the best average weather in all of Greece.

Rhodes and the Dodecanese — the second warm zone. Here winter daytime temperatures are regularly +15...+17, and Rhodes gets more than 300 sunny days a year — one of the sunniest corners of the country.

Let us gather the picture into a table — region, season and approximate daytime temperature:

The conclusion is simple: if you want a mild, warm winter without frost, that means the south of Crete and Rhodes. If you also need the infrastructure of a large city, the trade-off between warmth and amenities is covered well in our guide to the best places to live in Greece.

Sea temperature and the swimming season: when the water is warm

The sea is a significant factor in its own right, especially if you are coming for the beaches or thinking of a home by the water. The Greek seas warm up and cool down with a noticeable lag behind the air, so the warmest sea comes not at the peak of the heat but at its end.

• Winter (January–March). The water is +13...+16, a touch warmer in the south. Only hardened enthusiasts swim, and even then only on the very southern coast.
• Spring (April–May). The sea gradually warms: April +15...+16 (cold), May +19...+21 (already swimmable in the south).
• Summer (June–August). Comfortable swimming: June +22...+24, July +23...+25, August the peak at +24...+26.
• Autumn (September–October). The warmest and most pleasant water: September +24...+25 (warmer than June!), and still +22...+23 in October in the south.

So the classic swimming season in Greece runs from May to October, with the warmest water in August and September. Along the southern coast of Crete and on Rhodes the season stretches noticeably longer — into late October, and sometimes even November you can still swim there. In the Ionian and Mediterranean seas (the south and west) the water is on average warmer than in the northern part of the Aegean. This is worth bearing in mind when choosing seaside property, too: a “home by the water” in the north and in the south gives you a beach season of very different length.

Island climates: the Cyclades, the Dodecanese, the Ionian

The islands are the face of Greece on postcards, but there is a large climatic difference between them, and for living it is a decisive one.

• The Cyclades (Santorini, Mykonos, Paros, Naxos). A dry, sunny, windy climate. In summer the meltemi comes to the rescue — at the height of the heat a cool wind blows here, and +28...+30 is easier to bear than +35 in windless Athens. The downside is that same wind: in spring and summer it can be so strong that ferries are cancelled. The winter is mild, but damp and windy.
• The Dodecanese (Rhodes, Kos). The sunniest and among the warmest islands. Rhodes has more than 300 sunny days and a mild, warm winter. An excellent option for those who want both year-round warmth and developed infrastructure.
• The Ionian islands (Corfu, Kefalonia, Zakynthos). Western Greece is noticeably greener and wetter than the rest. There is more rain here in winter, which is why the islands are so lush and green. The summer is hot but without the exhausting wind; the winter is mild but rainy.

The general rule for the islands: they are milder than the mainland in winter (the sea moderates the climate) and more comfortable in summer thanks to the wind and the sea breeze. But there is also more damp in winter, and wind and rough seas can cut an island off from ferry links for a day or two. For permanent living this is a real factor — plan your logistics.

Mainland climates: Athens, Thessaloniki, the north and the mountains

Mainland Greece is more complex than the islands: the further from the sea and the further north you go, the sharper the temperature swings and the colder the winter.

• Athens and Attica. The city sits in a basin by the sea, and in summer this works against it: the concrete and asphalt bake, temperatures regularly reach +35...+38 and sometimes near +40 — the hottest capital in Europe. The winter, however, is mild: the January average is around +10, and snow is a rare event.
• Thessaloniki and the north (Macedonia, Thrace). Here the climate is already closer to continental. The winter is noticeably colder: the January average is around +6, with temperatures dropping to zero and snow in the city during cold spells. The summer is hot, +30...+34, but usually drier and without the Athenian extremes.
• Mountain regions (the Pindus range, Meteora, the northern mountains). A real winter with snow and steady sub-zero temperatures; in the highlands the temperature drops below -3, and there are ski resorts. Summer in the mountains is cool and pleasant — an escape from the lowland heat.

For living, choosing the mainland is always a compromise. Athens gives you warmth in winter, but a punishing heat in summer and urban smog. The north offers more pronounced seasons and a real winter — which some people love and others (especially after the islands) find cold. If your goal is the mildest possible year-round climate, the mainland loses out to the southern islands.

When to visit Greece: for a holiday, for living, for your budget

There is no universal answer — it all depends on your goal. Let us break down when it is best to visit Greece by objective.

• For the beach and the sea — June to September. The peak of warm water and sun is August–September. If you dislike heat and crowds, choose June or September instead of July–August.
• For sightseeing — monuments, cities, nature — spring (April–May) and autumn (September–October). Comfortable for walking, everything in bloom or gently turning golden, fewer tourists and lower prices. These are the famous shoulder seasons.
• For budget and quiet — winter and late autumn. Prices are at their lowest, but many seasonal hotels and tavernas on the islands are closed and ferries run less often. On the other hand, in the south of Crete and on Rhodes you can catch +18 and empty beaches.
• To understand whether the climate suits you for living — come twice: once in the August heat, once in the January damp. Everyone loves the Greek summer, but the real test is winter, with its cool, unheated homes and rain.

A separate word for those thinking not about a trip but about a move: climate is only one factor. Healthcare, infrastructure and winter transport access matter too. We have gathered much of this in a guide for anyone considering moving to Greece in retirement — there the climate factor is examined alongside the practical ones.

An expert’s view: what to look at beyond the thermometer

Over years of working with clients who move to Greece, we have built up observations worth sharing — so that you choose your location by more than a pretty summer picture.

• Test the house in winter conditions. Ask about heating, insulation and the orientation of the windows to the sun. The Greek winter is not frosty but damp, and poorly insulated housing turns +12 outside into an uncomfortable +14 indoors.
• Factor in island logistics in winter. The romance of an island in summer and its isolation in winter are two different things. Ferries run less often, and part of the local business shuts down. For permanent living this is critical.
• Match the climate to your health. If you cope badly with heat, the mainland and Athens in summer are not the best choice — look at windy islands or mountain areas.
• The south of Crete and Rhodes are the champions of the mild winter, and this is an objective fact rather than marketing spin: the southern position and the shelter of the mountains genuinely hold the warmth.

The climate of Greece is wonderful, but it is many-sided. The right choice of region can settle 90% of your future day-to-day concerns — whereas a mistake over location can only be fixed later by moving again.

In summary: what the climate in Greece is like and where it is warmest to live

Let us sum up. The climate of Greece is Mediterranean: hot dry summers, a mild rainy winter and an abundance of sun (up to 300 days a year in the south). But the country is climatically varied, and the blanket formula “Greece is warm” does not hold everywhere or always.

• The warmest place in winter — the south of Crete (Ierapetra) and Rhodes: +15...+20 during the day, with virtually no frost.
• The hottest in summer — Athens and the mainland: +35...+38, sometimes above +40.
• The coolest in winter — the north (Thessaloniki, +6) and the mountains (below zero and snow).
• The best seasons for living and for seeing the country — spring (April–May) and autumn (September–October).
• Swimming season — May to October, sea warmest in August–September.

In short: if you are coming for the beach, aim for late summer; if you are coming to see the country, choose the shoulder seasons; if you want to live in the warmth year-round, look at the south of Crete and Rhodes. And to turn “I love the climate” into “I live here legally,” you will need a residence permit — and the logical next step here is to work out exactly where to settle, in our guides to the best places to live in Greece and life on Crete.

The Greek climate for living: the pros, the cons and the pitfalls

The Greek climate as a place to live is one of the main arguments for relocating, and on the whole it really is good: up to 300 sunny days a year in the south, a mild winter, a long warm sea and clear-cut seasons. But there is another side to the coin, one the marketing brochures rarely mention.

The obvious upsides:

• Plenty of sun all year round — a proven boost to wellbeing and mood.
• A mild winter in the south — you can live without heavy winter clothing; on Crete and Rhodes the winter is warmer than our autumn.
• A long season of active life outdoors, by the sea and in nature.
• Dry air in summer — the heat is easier to bear than humid mugginess.

The pitfalls:

• Summer heat is intensifying. Heatwaves above +40 on the mainland are becoming regular — hard on the elderly and on anyone who copes badly with heat.
• Cold homes in winter. Southern homes were built for heat: thin walls, weak heating. A real +12 in a damp, unheated apartment feels colder than you would expect.
• Humidity and damp in winter on the islands — mould in poorly ventilated homes is not uncommon.
• The meltemi wind in summer on the Cyclades — a nuisance for some, cutting others off from ferries.

The takeaway: the best climate for living is the south of Crete and Rhodes (a warm winter, no frost), but even there you should choose a house with proper heating and insulation. It makes sense to judge Greece not by a summer postcard but by a real winter.

From climate to living: how to stay in Greece legally for the long term

Understanding the weather is only half the job. If, after your trip, you realise you want to spend not two weeks in Greece but a whole winter — or to live here permanently — a second question arises: on what legal basis. A tourist Schengen visa allows a maximum of 90 days in any 180-day period, and that is not enough for a long overwintering stay or a move.

To stay in Greece legally for the long term, there are several residence permit routes:

• Golden Visa — a residence permit for investment in real estate. The most popular route: you buy property at the set threshold and receive a renewable 5-year residence permit for the whole family, with minimal presence requirements. Convenient precisely for those who want a home by a warm sea and the right to live in the country.
• Digital nomad residence permit — for remote workers with proven income.
• Financially independent person residence permit (FIP) — for those living on passive income or a pension.

In other words, the mild climate of the south and a home by the sea are not only about holidays — they are a real opportunity to settle here. Which status suits your situation — budget, source of income, family composition — depends on the details, and this is precisely the kind of question we handle end to end.
