Maltas climate is strongly influenced by the sea and is typical of the Mediterranean. The Islands have a very sunny climate with a daily average of five to six hours sunshine in mid-winter to more than 12 hours in summer.Winters are mild, with the occasional short chilly period brought about by the north and north-easterly winds from central Europe. Summers are hot, dry and very sunny. Summer Temperatures ranges between 24°C in May and 32°C and more in August, which is the warmest month.
Along the coast the summer temperatures in are often cooled by cooling sea breezes, but in spring and autumn a very hot wind from Africa occasionally brings high temperatures and humidity. This is known as the Sirocco- this wind affects Greece and Italy as well; in Malta the air is generally drier because of the short sea track from the African coast. Annual rainfall is quite low, averaging 700mm a year, and the length of the dry season in summer is longer than in neighbouring Italy. Sea bathing is quite possible well in to the winter months, and the beach season can last until mid- to late October.
Lightweight cottons and linens are worn between March and September, although warmer clothes may occasionally be necessary in spring and autumn and on cooler evenings. A light raincoat is advisable for winter.
The climate of Malta is classified as Csa Climate; a warm temperated mediterranean climate with dry, warm summers and moderate, wet winters with the warmest month above 22°C over average.
