Weather in Santorini

As with the rest of the Cyclades Islands, the weather in Santorini is varied. This guide will help you choose the best time to plan your visit to this spectacular island.

Warm summers and extended period of sunshine can be expected on Santorini, a typical Mediterranean climate. The winter months though see mild, windy and rainy days.

The geographic location around the ancient volcano in the southern Aegean plays a role with the unique weather of Santorini. The distinctive micro-climate formed around the island consists of excessive humidity, reaching up to 100% at times.

As the harsh volcanic soil is totally dry this has all led to the island’s flora evolving into plants with smaller roots and bigger leaves, so as to absorb the atmosphere’s humidity.

The year can be split into two main seasons, namely the warmer, dry months from April to October. The hottest months being July and August and the colder, rainy season which is seen in the period from November to late March. January and February are the coldest and windier months.

Not all bright sunny weather…

In the dry months, the weather generally remains stable with clear skies, bright sunshine, and very little rainfall. Even in the winter months, while there is rain it is uncommon to experience extended periods of rainy days.

Overcast skies usually break after a few days, unlike in other parts of the world. Be sure to pack a sweater and jacket when visiting Santorini in October as temperatures get cooler in the evenings.

The island is subject to strong winds, most commonly the maistros coming in from the northwest. The southerly winds, known as ostria can be stronger than the northerly gusts, while locals welcome the meltemia from the northwest.

These “strong breezes” are a Santorini weather phenomenon usually met around the islands of the Cycladic complex. The main characteristic being the sudden drop of the wind at sundown; as they usually blow between mid-July and mid-August, these winds are a much welcome relief during the hot summer days.
