Climate and Average Weather in Greece

The biggest part of Greece enjoys a Mediterranean climate that is characterized by mild winters and dry hot summers. In the higher parts of Greece you can experience pretty cold periods during winter. In some parts of Greece it is even possible to ski.

Snowfall during the winter months is not only possible on the mainland and mountains, even the island of Crete sometimes has to deal with a layer of snow. The capital Athens is even regularly paralysed by heavy snowfall during the winter months. The weather however can turn very quickly, with temperatures rising above 10 degrees Celsius (50°F) within 24 hours and all the snow disappearing as quickly as it came. On the islands the weather in winter is often mild and temperatures are usually between 5 and 15 degrees Celsius (41 - 59°F).

Most of Greece enjoys warm weather caused by its Mediterranean climate. As a result, Greece has quite long and warm summers in which it sometimes does not rain for weeks. The best time to visit Greece and the Greek Islands begins in May, when the mean temperature is 21 degrees Celsius (69° Fahrenheit) and rainfall is less than 1.5 cm (0.59 inch).

The summer sun season continues until October, although in that month on some islands it can get colder, windier or wetter. July has monthly average temperatures of 28° C (82° Fahrenheit) and rainfall less than 0.5 cm (0.19 inch). Especially the months of July and August are sun-drenched on the Greek islands.

September, with an average temperature of 24° C (76° Fahrenheit) and less than 1 cm (0.39 inch) of rain is a great month to visit. Also the first two weeks of June have perfect, sunny and warm weather, with little clouds or rain. Most rain falls between November and February.
