Weather in Santorini

The weather in Santorini is varied, as can be said about the rest of the fellow Cyclades Islands. A typical Mediterranean climate for the most part, this dramatic volcanic island experiences warm summers with extended periods of sunshine, followed by mild, windy, and rainy winters.

The geographic location around the ancient volcano in the southern Aegean Sea plays a role with the unique weather Santorini is known for. 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 – the colder and windier months being January and February. In the primary tourist season between May and September, the weather is generally pleasant and warm with the occasional exception. The best weather in Santorini can be enjoyed from June through September when the sun shines in all its glory, baking sun worshippers as they lay about the island’s volcanic beaches and numerous Santorini hotels. During this period, the waters of the Aegean offer ideal temperatures for swimming; at its warmest levels during August and the first part of September. The summer days are truly glorious and on select occasions, the weather is so clear that it is possible to see over 70 nautical miles ahead to the island of Crete.

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.
