Climate and Weather


The beautiful summer weather is one of the reasons why Mykonos is such a popular holiday destination. July and August are, of course, the summer months par excellence and during these months the average temperature is around 25 to 26 °C with daytime temperatures often just above 30 °C. During heat waves, temperatures rise to 35 °C or even higher. During heat waves, the temperature rises to around 35 °C or even higher. Fortunately, in the coastal area, where most tourists stay, temperatures are tempered by a cooling sea breeze, the "meltemi". The amount of precipitation in summer is almost negligible and very infrequent. Sunshine determines the summer on Mykonos, a sun that shines on approximately 300 days of the year, including the winter period.


Autumn is an excellent time to visit Mykonos. Especially in September, it is often fantastic (summer) weather with temperatures still close to 30°C during the day and between 15 and 20°C at night. The sun still shines in this month about eleven hours a day. Even in October, it is often still quite warm with daytime temperatures between 20 and 25 °C. The chance of precipitation does however increase in October, which is also the start of the rainy season on Mykonos with an average of around 170 mm of precipitation, which fortunately often falls in short, heavy showers. Therefore, there is still plenty of room for sunshine, about eight hours a day. In November, the daytime temperatures are already much cooler, ranging between 15 and 20 °C. At night, the temperatures are lower than in the previous year. At night, the temperatures are generally just above 10 °C. As in October, November also sees a fair amount of rain.


The winter on Mykonos is best described as mild but wet. Strong winds sometimes cause stormy weather and often thunderstorms. Winter temperatures can cool down to around 5-6° during the day. It rarely gets much colder, thanks to the seawater, which never falls below 16°. Autumn/winter is the wettest period of the year, with most rain falling between October and February. Due to the constant presence of wind, it never rains for long in the winter, and the sun shines regularly and the temperature still rises to 10-13°C. On winter days, the sun shines an average of 4-5 hours a day.


Spring, like autumn, is an excellent time to visit Mykonos, as both air and sea temperatures start to rise without being too hot. The sun shines in abundance and the beaches are much less crowded than in summer. At night, however, it can still be quite chilly, so it is better to wait for the summer for the nightlife. Precipitation decreases from March onwards, although heavy rainfall cannot be ruled out. As the season progresses, temperatures rise and rainfall decreases. In May, one can enjoy plenty of sunshine, temperatures of 20-25°C and around 35 mm of precipitation practically every day.

Of the winds that affect Mykonos, two are the most common. During the winter months, strong winds often blow from the south, one of the most famous being the 'Sirocco', which brings desert sand from the Sahara every spring in the form of 'red' rain. As summer approaches, a cooling north wind, the "Meltemi", blows almost every day in the months of July and August and only decreases in strength at night. Gale force winds are not uncommon during the summer period.
