Santorini weather is best described as dry in summer and mild in winter. This kind of climate that Santorini enjoys is due to the islands’ geographic location: Santorini sits on the southern part of the Mediterranean Sea. The fact that the islands were formed around a volcano has a lot to do with the Santorini weather as well.

The general mildness of the weather in Santorini all year round makes these islands the perfect holiday getaway anytime of the year.

Summer in Santorini, perhaps more correctly called the dry season, lasts from May to October. The weather in Santorini during the dry season is characterised by continuous bright sunshine that lasts for 12 hours throughout the day.

Temperature averages between 22.5 to 30°C when the dry season reaches its peak in July. The temperature usually drops after sundown, however, and this promises cool summer nights in Santorini.

Because it is the dry season, it is naturally to be expected that there would be no rainfall in Santorini during the summer months.
