Sea temperature in Italy

Live water temperatures and swimming conditions across 301 beaches on the Italy coast.

Best time to swim in Italy

The sea in Italy peaks in August, when the water averages around 26°C.

The main swimming season runs from June – October, when surface temperatures stay comfortable for extended sessions.

On average, 5 months a year sit above 20°C — the threshold most swimmers describe as pleasant without a wetsuit.

Shoulder months like May and November are noticeably cooler but often quieter, with fewer crowds and steadier weather.

Outside peak season the water drops toward 16°C, so a 3/2mm shorty or full wetsuit makes long swims much more comfortable.

The coldest month is typically February at around 13°C, when cold-water swimmers dominate the coast.
