Weather in Greece

The climate in Greece differs somewhat between regions. The northern parts of the mainland have colder winters and hot, humid summers. On the other hand, the southern parts of the mainland and the islands to the southeast have a more typically Mediterranean climate with milder winters and hot, dry summers. However, in general it can be said that Greece has warm summers and mild winters.

Broadly speaking, snow in Greece becomes less common the further south and the closer to sea level one goes. Some of the higher mountainous areas can have semi-alpine climates with heavy winter snowfall. It does occasionally snow in and around Athens, however.

The hottest months of the year are July and August, where temperatures can reach 100°F (40°C) over most of Greece. These months are also when the Meltemia blows, a northerly wind sweeping the mainland’s east coast and the islands in the Aegean Sea to the east of the mainland. This reduces humidity, but also lifts skirts, kicks up sand and blows away washing. 

The islands in the Aegean Sea to the west, the western parts of the mainland and the Peloponnese peninsula, just to the south, manage to escape the Meltemia but these are also the areas with the most rainfall in Greece. 

Weather in Greece tends to consist of longer summer and winter seasons with quick, transitional spring and autumn seasons. Spring and autumn are arguably the most pleasant seasons, especially around May, June, September and October. 

Rain starts from the middle of October and can continue through February, punctuated by days with a mild winter sun and clear skies.
