One of the reasons why Santorini is so popular with tourists is its idyllic climate. It rarely rains and even in summer, temperatures are not as high as in other parts of Greece and the Mediterranean as a whole.
During spring and summer, the sky is almost always free of clouds and shines with an intense blue, while the climate is more dynamic during the months of autumn and winter.
The island of Santorini enjoys the typical moderate Mediterranean climate, with hot, sunny and dry summers, and mild and brief winters. During the summer months, average temperatures reach 34° in July, while in winter they do not fall below 9° in January.
The months with precipitation are January and February, while in months like October and March the climate remains relatively hot.
The best time to travel to Santorini is between April and June and from September to the beginning of November. In the summer months (July and August especially) it is very hot, while spring is the best time, high temperatures are avoided, visitor attendance is lower and accommodation is cheaper. Winter is usually not very rainy and autumn is unstable.
Spring is the best time to enjoy the sea, as it’s warmer, more peaceful and welcoming. The lack of haze allows the days to be bright and transparent and also make the best sunsets in the world possible. The colors of the Mediterranean paint Santorini during this part of the year. Perhaps the only disadvantage of this time of year is that the days are slightly shorter.
Summer is the mix of the previous 2, but with many visitors and higher prices. If you’re into partying and nightlife and don’t mind the heat, this might be the best season for you to visit.
The winters, from December to March, are rather cold and unpredictable. It is the ideal time for a cultural trip to go on an archaeological and scenic route of Greece and perhaps leave the sea and islands for later in the year.
Temperatures vary with a daily average of 29ºC in summer and 12ºC during winter. However, the humidity can be very high, which translates into normally cloudy horizons. In spite of this, the constant breezes of the island take away the sticky heat and make the summer days quite comfortable, even when temperatures reach over 30ºC. Winter winds can be quite cool and temperatures can become frigid at night.
