The climate in Greece allows sailing nearly all year around, The weather follows a typical Mediterranean climate pattern with hot, dry summers and mild rainy winters. The country receives a lot of sunshine, for which it is rightly famous. Mid-May to Mid-September is very dry, while July and August are unlikely to see any rainfall at all.
Spring is a delightful time of year in Greece with fine, dry weather and pleasantly warm temperatures around 20 degrees Celcius. It is the perfect season for an active holiday and to combine your sailing experience with exploring the picturesque villages of the islands, enjoying the scenic landscape sightseeing, hiking or biking. The sea will still be a little cool with an average temperature of 18 degrees Celcius. So you can still enjoy a short swim and other water activities like stand up paddle boarding (SUP), and sunbathing.
Summer weather in the islands begins in May with daily highs in the mid-20s. By July the daytime temperature is often in the 30s. July and August are the peak summer months (around 35 degrees Celsius) when the temperature will rarely drop below 20 degreesCelcius even at night. This is the perfect time for sun and sea -lovers as the water is up to 25 degrees Celcius warm!
During summer the islands are visited by the cooling “meltemi” winds – sea breezes that blow down through the Aegean. This strong northerly wind makes for challenging sailing, especially in the Cyclades in July and August. The other areas of Greece are less affected by the meltemi. It’s unusual for storms to prevent sailing in the Saronic.
In Autumn the sea is pleasantly warm with 21 degrees Celcius and often remains so until late October. Those who dislike extreme heat will find autumn temperatures comfortable during both day and night. Rain is rare until November. However, an occasional shower is possible. The meltemi wind subsides, seas are usually calm and it is an ideal period to plan a trip to the Cyclades.
