Malta’s summers are long and very hot with practically no rainfall. June to September experience average daily highs of around 28-32°C. These high temperatures are often relieved by cooling sea breezes. However, the island can see temperatures soaring up into the 40s when the sirocco wind blows from Africa. This hot dry wind blows in from the African continent bringing stifling and uncomfortable temperatures. Summer nights are very warm too, with temperatures in July and August rarely falling below the 27-28°C. This makes air-conditioning very desirable!
