The best seasons to travel to Greece are spring and early autumn when the weather is pleasant, the sun is gentle, and tourist sites and beaches are less crowded. Due to the country’s Mediterranean climate, the summer months (July-August) attract the largest influx of tourists to the islands—which means significantly higher hotel rates and fully booked ferries.
However, in spring (May-June) and early autumn (September-October), the sea is still pleasant for swimming, nature is in full bloom, and room rates are lower. Greece is also attractive in winter for those seeking an urban vacation in Athens or nature trips in the mountainous north. Just keep in mind that on the islands, most businesses close, and in Northern Greece, temperatures drop, making snow a common sight on the mountain peaks.
Weather in Greece for the Upcoming Days
Weather in Greece in January
Greece in January is wintry and quiet. Trips during this month are suitable for those who prefer archaeological sites devoid of crowds or skiing in the northern mountains. In Athens, temperatures range between 7 and 13 degrees Celsius (45-55°F), and it is often rainy. On the islands, winds can be very strong, and most ferries operate on a reduced schedule. In Northern Greece (areas like Zagori, Tzoumerka, and Thessaloniki), temperatures often drop below freezing, and snow covers the peaks. Packing warm clothes, a high-quality raincoat, and boots is highly recommended. This is an excellent time to enjoy local taverns, most of which are warmed by a crackling fireplace.
Weather in Greece in February
The weather in Greece in February is still cold, but there are occasionally sunny breaks known as the “Halcyon Days.” Temperatures in Athens this month are similar to January, around 14 degrees Celsius (57°F) during the day. The north remains very cold, with snow in ski resorts like Parnassos. February is the month of carnivals in Greece, and the atmosphere in the cities is joyful despite the chill. The islands are mostly still dormant. You are likely to encounter rain, so packing warm clothes and an umbrella is strongly advised, but you will also get to enjoy the first almond blossoms heralding the arrival of spring.
Weather in Greece in March
Weather in Greece in March is unpredictable and marks the transition from winter to spring. In southern Greece and islands like Crete and Rhodes, the days start to warm up, with average temperatures reaching 16 degrees Celsius (60°F). The north remains cool. Greek Independence Day falls on March 25th, bringing parades and celebrations. This is a great month to explore the culture and history of Athens on foot without the intense summer heat. Rain is still possible, so a light jacket is a must. The skies begin to clear, and nature starts to cover itself in green carpets that will disappear by summer.
Weather in Greece in April
April is a magical month in Greece, especially if the (Greek) Orthodox Easter falls during this time. Imagine a country that loves visitors waking up to life. The villages are freshly whitewashed, nature is at peak bloom with wildflowers everywhere, and temperatures rise to around 20 degrees Celsius (68°F). In the Cyclades islands (like Mykonos and Santorini), the season officially begins to open. The sea is still a bit cool for swimming for most people, but the brave ones are already jumping in. This isn’t just any month; it’s the perfect time for trekking before the sun gets too strong.
Weather in Greece in May
May is arguably the most ideal month to be in Greece. Temperatures range between 20 and 25 degrees Celsius (68-77°F), and the waters begin to warm up. This is the time when everything is green, contrasting with the scorched yellow of August. Ferries to the islands start operating more frequently. While there might be light rain here and there, mainly in the mainland north, it passes quickly. May is simply perfect for winery tours, wandering through island alleyways without being pushed by thousands of tourists, and enjoying pleasant sunshine that doesn’t burn.
Weather in Greece in June
June in Greece heralds the arrival of the official swimming season. Temperatures rise to around 28-30 degrees Celsius (82-86°F), but without the humidity and congestion of July and August. In the Cyclades, the northern “Meltemi” winds sometimes begin, cooling the air in the evenings. The skies are completely blue and clear. This is the ideal time for a perfect beach vacation combined with sightseeing. It is recommended to pack swimsuits, a wide-brimmed hat, and plenty of sunscreen. Take advantage of the time for sailing tours, water sports, and hanging out at beaches and waterfront taverns.
Weather in Greece in July
In July, Greece enters the peak of summer. In Athens, the heat can be intense, reaching 35 degrees Celsius (95°F) or more, so visiting the Acropolis early in the morning is recommended. On the islands, the Meltemi winds strengthen, helping to break the heat, though the sea can get choppy. Northern Greece (Halkidiki peninsula) is packed with vacationers. Rain is extremely rare. This is an excellent time for a pure beach holiday, beach parties, and local festivals held under the open sky until the small hours of the night.
Weather in Greece in August
In August, all of Greece is on vacation. Locals also take their leave around August 15th (Assumption Day), and the islands are filled to capacity. Temperatures are very high, hovering around 32-38 degrees Celsius (90-100°F). The water is warm and pleasant for long swims. August is the most vibrant month in terms of entertainment and nightlife, bars, and clubs in Mykonos, Ios, and Zakynthos. It is recommended to pack very light clothing, but bring a thin jacket for the evening.
Weather in Greece in September
September in Greece is considered by many to be the best month of the year. The scorching summer heat calms down, but the water remains very warm. Temperatures are pleasant, around 28 degrees Celsius (82°F) during the day, and sleeping without air conditioning becomes comfortable again at night. On the large islands and in Athens, everything is still open and lively, but without the crowds of August. In Northern Greece, you start to feel autumn in the evenings. This is the perfect time to combine beach relaxation with nature trips and archaeology.
Weather in Greece in October
October in Greece marks the end of the tourist season on the islands. In the south (Crete, Rhodes), you can still swim during the day as temperatures are around 24 degrees Celsius (75°F). In the north and Athens, it begins to cool down, and the first rainy days may occur. The smaller islands start closing down for winter. The atmosphere is calm and romantic, prices drop, and the sunsets in Santorini are more beautiful than ever when unobstructed by crowds of tourists.
Weather in Greece in November
Weather in Greece in November turns more wintry. Rains return, mainly in Western Greece and the Ionian Islands (like Corfu). Temperatures drop to the 15-18 degrees Celsius (59-64°F) range. Tourist islands are almost completely empty, and ferry lines are reduced. This is an excellent time for a city trip in Athens or Thessaloniki, visiting museums without queues, and enjoying the local culinary scene and winter sweets. Packing warm clothing and an umbrella is recommended.
Weather in Greece in December
In December, Greece gets festive, but in a different way than classic Europe. Instead of Christmas trees, in many squares, you will see illuminated boats (an ancient tradition). Temperatures in Athens range around 10-15 degrees Celsius (50-59°F), but in the northern mountains (like Pelion or Zagori) it is snowy and cold, and ski resorts open up. The atmosphere is very festive; markets and shops are decorated, and bakeries sell traditional desserts: Melomakarona (honey cookies) and Kourabiedes (almond cookies covered in powdered snow). Athens is very vibrant this month with street performances and excellent nightlife. It is recommended to pack very warm clothing if heading north and a good coat for Athens.
