Best time to visit Santorini, Greece

Our verdict

The best time to visit Santorini is May-July

While Santorini is a popular destination to visit all year round, May-July is the ideal time to go due to a number of factors such as the climate, cost of travel and accommodation, as well as avoiding peak holiday periods.

In summer, the average maximum temperature is around 26℃ (79℉), but temperatures can sometimes reach as high as 27℃ (81℉) on the hottest days of the year. The weather in the winter, especially around January, can reach a minimum of 9℃ (47℉).

The longest days between sunrise and sunset in Santorini are usually in August, so if you want to get the most out of your daytime activities, be sure to plan your visit around this time. You don’t want to get wet on your holiday, do you? Well if you’re trying to avoid the rain, then steer clear of Santorini in February.
