Sicily has a typical Mediterranean climate with mild and wet winters and hot, dry summers with very changeable intermediate seasons.
In the deep midwinter the average temperatures on the coast should still be hovering around the 13°C mark, though on sunny days it can be warm enough in the sun to walk around in a t-shirt.
On February the days starts to get warmer and on March the winter is truly over, the days are longer and the wild flowers starts to grow everywhere to explode on April, while people start to take their first baths all over the coast thanks to the great temperatures; the array of colors is spectacular.
After a colorful and perfumed May, Sicily is inebriated with the first smells of summer while the sun is shining high in the sky. The temperatures everywhere are generally agreeable but sometimes the Scirocco wind can bring some hot days. The sea is warm but the beaches are crowded only on weekends, when locals are free from work.
During July and August months, temperatures reach their highest peaks, bringing people to the beaches or fresh mountains: it is popular to hike on the Etna to take a break from the hot cities, the crowded beaches and to cool a little beat.
While September is approaching, the summer is often interrupted by coastal storms but temperatures remain very comfortable and the beaches starts to be more relaxing but still give you summer vibes.
After this warm month, autumn is starting to approach and seasonal rainfalls contributes to develop a stunning variety of mushrooms: people starts to go out on weekends to collect as much as possible!
The real autumn arrives only in November, with temperatures that can still reach the high twenties during the day and cool in the evening. This is generally the month with the highest rainfall.
On December the cold days are breaking through the island but you can still find agreeable temperatures especially during the day time.
Snow falls in abundance above 900–1000 meters, but stronger cold waves can easily carry it in the hills and even in coastal cities, especially on the northern coast of the island. The Etna enjoys a fully mountain climate, with heavy snowfalls during winter.
Total precipitation is highly variable, generally increasing with elevation. In general, the southern and southeast coast receives the least rainfall (less than 50 cm (20 in)), and the northern and northeastern highlands the most (over 100 cm (39 in)).
