Greece Weather Guide

With a diverse topography of mountainous regions, islands and a mainland, the weather in Greece varies somewhat. Overall, Greece’s climate is Mediterranean with loads of sunshine, not too much rain and mild temps. Really, there are only 2 seasons in Greece – hot and dry from April to September, and mild and wet from October through to March.

Season and Clothing

Summer: June to August

Summer in Greece is smoking hot! During summer, it hardly rains in Greece. The days are dry and warm on the mainland with Athens reaching 40-plus degrees on some days, while mountainous regions generally have lower temps. On the islands, the temps are in the 30s by July and will rarely drop lower than 20 degrees, even at night. It is high season though, so you will pay more for rooms during the summer months. Sandals, swimmers and shorts are perfect for the islands, shoot for shorts, t-shirts and dresses in Athens.

Autumn: September to November

Autumn could be the perfect time to visit Greece, particularly in September and October. In November, you might find some of the businesses, and especially on the islands, shut up shop and bus and ferry services will be reduced. At the start of autumn though, it’s divine. The weather is lovely and you won’t have to fight the crowds at tourist attractions. Make sure you pack clothes for layering to accommodate the cooler nights.

Winter: December to February

You don’t really think of Greece as a cold place, but the temperature sure can drop in winter with record lows in Athens of -10 degrees Celsius. Generally, winter in Greece is mild in lowland areas while the mountains are covered in snow – yes, there are a few ski resorts here too. The Greek Islands are cold, wet and kind of deserted, so it’s not the best time to visit unless you want a ‘Castaway’- type experience. Bring an umbrella and waterproof shoes if you’re getting out and about in Athens and the islands, or head indoors to check out the museums and historic sights.

Spring: March to May

After a chilly winter, the weather in March is still quite cool in Greece, although there are many crisp, clear-sky days. The lovely lowland flowers are blooming and there’s still snow on the mountains ‘til around May. For a mild spring climate, shoot for Greek islands such as Crete or Rhodes. By May, the weather is warming up and it’s quite a good time to visit as the hordes of tourists haven’t arrived and it’s warm enough to swim, so pack your swimmers and lightweight clothes.
