MYKONOS - WEATHER
The two most common elements of climate for which Mykonos is famous are sunshine and wind. Rainfall is infrequent, generally falling between the months of February and March, allowing the sun to shine for as many as three hundred days of the year. Because of this arid condition natural vegetation is limited.Summer
During the summer months the temperature may occasionally reach the upper 90's F, but due to the cooling factor of the frequent winds an average of 82°F can be expected. As the season heads toward summer the north wind takes over and with various degrees of strength, blows daily. The most notable of these winds is the 'Meltemi' that during July and August will blow steady throughout the day and then reduce its velocity during the night. Gale-force winds are not uncommon.Winter
Winters on the island are mild with an average temperature of 60°F. It is only on very rare occasions the thermometer may reach freezing. Due to the moderating influence of the surrounding sea the island's temperatures are usually 2 degrees warmer in the winter and 2 degrees cooler in the summer than mainland Athens.
During the winter months heavy winds from the south arrive and often bring with them electrical storms. Of these the most famous wind is the 'Sirocco' which every spring brings sand from the deserts that border the Mediterranean in the form of red rain.
Sunglasses, hats and a generous handful of sun protection cream are a must-have and must-use during your Mykonos vacation. But, as strong winds called 'meltemia' can be a regular phenomenon in late summer, especially in August, make sure you also bring a sweater.
