Sardinia Weather in May

destination intro image

What’s the weather like in Sardinia in May? 

Sardinia has a typical Mediterranean climate and is located in the Tyrrhenian Sea, off the west coast of Italy. This means the second largest island in the Mediterranean has long hot summers that start to take off in May. If you’re going at this time, you’ll have plenty of warm and sunny weather with not much rain. There’s differences in weather across Sardinia as it’s quite hilly. You’ll be driest in the south, while the wetlands that surround the capital of Cagliari in the south east, have mild and humid weather. Sea breezes and winds from the Alps will help to keep you cool, although things can get really hot when the Sahara Desert sends warm winds over.


The average high in Sardinia is 22ºC in May, which drops to quite a cool 12ºC at night. The sea temperature is 17ºC, while humidity’s low. There’s 19mm of rain over nine days, and you can expect 14 hours of daylight with nine hours of sunshine each day. Make sure you bring plenty of sun cream as UV levels will be very high. The sun goes down at around 8.30pm for much of the month.
