Attica’s climate is typical of the Aegean region of the Mediterranean. The hottest, and driest, time of the year is, of course, summer with July and August being the hottest months, and when daytime temperatures can soar into the upper 90s. As with many parts of Greece, the region has some amazing beaches, and these are packed in the summer heat. But even in the hottest days of summer you’ll find plenty of places to sit in the shade, while you cool off at a cafe.
April and May, as well as September and October are considered the most ideal times to visit as you still get warm and sunny days, and warm nights with pleasant breezes coming off the Aegean.
The winters are cool and mild, with temperatures often in the upper 50s and low 60s during the day, and a bit cooler at night. This can be the rainy season as well, and in the mountains there is some snowfall, but never in abundance. The beaches, and resorts along the Aegean are shut down, but there is always an abundance of things to see around Attica, and even in the winter there is still plenty to do. The museums, shops, restaurants and hotels are open throughout the year.
