This post is also available in: Čeština Deutsch polski

The island of Mykonos has a very dry climate with high summer temperatures mitigated by the constant breath of the wind Etesian (Meltem) blowing from the north in the summer months. The sun shines on the island for about 300 days a year. The poor rains – in the island fall in average 367 mm per year – are concentrated in the winter months, those between November and January, the wettest months are December and January. In the months between April and September rains are very rare and from June to August it does not rain hardly ever.

In summer, if the wind is not blowing, temperatures can soar beyond 35 ° C, but the breath of the typical greek wind, the Etesian (Meltem), which usually blows constantly in all the Cyclades islands means that the average temperatures are around 28 ° C in the warmest month of August. The average minimum temperatures in July and August is 23 ° C. The winters have very pleasant temperatures, the average maximum temperatures are 14 ° C in January which is the coldest month, while the average minimum temperatures reach the minimum of 10 ° C in January and February. The prevailing winter wind is the Sirocco, a wind from the south that sometimes carries sand from the African desert.

The temperature of the sea in Mykonos reaches 25 ° C in August, but remained above 22 ° C between June and October.


The best time to visit the island of Mykonos are the months from April to October.
