Best time to visit Cagliari

June is the best month in Cagliari, scoring 97 out of 100, with February the weakest at 64. The 33-point spread means timing is worth planning around without being decisive. The good window runs May to October — 6 months within ten points of the best.

August is the warmest month at 28.2 °C and February the coolest at 13.8 °C — a 14.4 °C spread across the year.

There is a real wet season here. January, November and December carry the rain — up to 12 wet days in a month — while June to August drop as low as 1. That 11-day gap is the biggest single difference between a good month and a bad one in Cagliari, and it moves further than the temperature does.

The sea is comfortable for swimming in June to October — 25.7 °C at its warmest against 14.1 °C at its coldest. The water peaks a month or two after the air does, so the best swimming falls later in the year than the best weather. Daylight runs from 9.4 hours in winter to 14.9 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are June, July, May. The one to think twice about is February. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
