Santorini Yearly Weather Summary

The climate in Santorini is typical of the Mediterranean climate: generally extended periods of sunshine throughout most of the year, relatively warm and dry summers and mild and rainy winters.

The year can be broadly subdivided into two main seasons: the warm and dry season lasting from April until October and the cold and rainy season lasting from November until the end of March.

Long periods of consecutive rainy days are not common in Santorini, even during the winter, and the sky does not remain cloudy for more than a few days in a row, as it does in other regions of the world.

During the warm and dry season the weather is usually stable, the sky is clear, the sun is bright and there is generally no rainfall. A sweater/jacket is advised, especially in April and October, as evenings often bring cooler temperatures.
