Seasonal Climate Variations / When to Go

Many people choose to holiday in Thessaloniki when the climate is at its most favourable, in late spring / early summer, or at the very beginning of the fall. Both May and September are especially appealling, with temperatures averaging 25°C / 77°F, and the nights feeling less humid than those in the peak of summer.

If you choose to holiday in Thessaloniki during the summer weather, as many thousands of tourists do, then sunbathing on the beaches becomes the main draw card at this time of the year. Swimming in the sea and heading into the mountains offer excellent ways to cool down during the Greek summer.
