Sicily in May experiences Mediterranean springtime conditions. Average temperatures range from comfortable lows in the mid-teens Celsius overnight to pleasant highs in the low twenties during the day. Sunshine is abundant, and rainfall is relatively low, making it an attractive time for outdoor activities. Sea temperatures are typically cool but becoming increasingly suitable for swimming towards the end of the month.
This period offers a favorable balance between pleasant weather and fewer crowds compared to the peak summer months. The milder temperatures make exploring historical sites and enjoying the natural landscapes more comfortable. Historically, May has been a time for agricultural activity in Sicily, with the land flourishing after the spring rains. This translates into a vibrant landscape and the availability of fresh, seasonal produce.
