We may say that the climate on Sicily is hot. And it is true especially as far as summer is concerned, which is the main tourist season on Sicily. It is because Sicily is situated in the southern part of the Mediterranean coast of Europe.
It is hot in Sicily in summer, the sky is blue, the temperature in the afternoon is about 36-40˚C. You should pay attention to the fact that the most popular month for the holidays in Europe is August, but it is not the best period to visit Sicily, because the Sicilians are also on holidays in August. In August you may find a lot of shops, restaurants and other places closed, because the owners of these places are on holidays and spend their free time on the beaches of Mondello and Castellamare.
If you are thinking of going to Sicily, the best months to do it are April, May, June and September.

Besides this fact, spring is a season when all the orchards are in blossom and the nature looks beautiful. May is also a month of tunny-fishing, the tradition of which is more than 500 years old and was even described by the famous French traveler Cousteau in his books.
Storms on Sicily are quite common. They happen there all the year round. A lot of them are the results of sirocco. Siroccos are the winds which blow from North Africa. They bring dry hot air of the African deserts to the provinces of Catania, Ragusa, Syracuse and Agrigento. The rate of siroccos can reach 100 km per hour. The strongest winds blow on Sicily in March and November.
