While there's really no bad time to visit these idyllic isles, we've put together a seasonal weather guide so you know what to expect and what to pack for the perfect Greek Island getaway. Opa!

Season and Clothing

Summer: June to August

With a prevailing Mediterranean climate, summers in the Greek Islands are typically dry and hot. As the temperatures rise in summer, so do the tourists with the islands coming into full swing in August so expect plenty of crowds. While temperatures are at their balmy best during this time, strong sea breezes are also common in summer, which can sometimes cause cooler weather along the coastline.

Average temperatures: 20 - 30 degrees Celsius.
Appropriate clothing: Casual summer clothes, swimsuits and sandals.
Don’t forget: Sunscreen, sunglasses and a hat.

Autumn: September to November

Warm weather continues on during autumn with the chance of rainfall particularly low in September. Following this month, from October the Greek Islands slip back into the off-peak tourist season with reduced ferry services, fewer tourist facilities and quieter streets. As such, autumn on the islands can be much cheaper while the weather is still good for swimming. It's also a great time to explore the ancient ruins, inland olive groves and other sights away from the beaches, resorts and towns.

Average temperatures: 16 - 22 degrees Celsius.
Appropriate clothing: Light layers and a jacket or jumper for night-time.
Don’t forget: Your swimsuit.

Winter: December to February

Winter in the Greek Islands is exceptionally mild. Even at its lowest average temperature, which is around 10 degrees Celsius, the days can still be quite clear and beautiful, particularly on Rhodes and Crete. At other times however, rain is common. While the islands are at their quietest in winter, it's not completely dead. Life still goes on, on the islands and even though some of the bigger resorts tend to close, many hotels still remain open for business. If you want to enjoy the beautiful island scenery without the crowds, then winter is the perfect time to do so.

Average temperatures: 10 - 15 degrees Celsius.
Appropriate clothing: Light layers and a coat for night-time.
Don’t forget: A good book to while away any rainy periods.

Spring: March to May

By the time March hits, the air temperatures begin to warm up, wildflowers come into bloom, the green fields brighten and the Greek Islands begin to wake up. For some it's still probably a little too chilly to swim, but then again, a cold spring dip never really hurt anyone. Spring also falls around the Greek Easter period, which is a fantastic time to observe Greek culture and Orthodox traditions on the islands.

Average temperatures: 13 - 17 degrees Celsius.
Appropriate clothing: Light layers plus a jumper.
Don’t forget: Your camera.
