Cagliari in September
Great time to visit
September offers the best of both worlds - still warm enough for swimming but cool enough for comfortable city exploration. Prices start dropping while weather stays excellent.
Weather
September brings blessed relief with highs of 28°C and lows of 21°C. The oppressive heat breaks, but the sea stays warm at 23°C. Rain returns occasionally with about 4 wet days, usually brief afternoon showers.

All Months
May through October gives you the best weather, but each month feels different. May and June offer mild temperatures around 24°C and fewer crowds. The sea warms up enough for swimming, and restaurant terraces reopen after winter.
July and August bring heat and tourists. Temperatures hit 30°C regularly, and Poetto beach fills with Italian families on vacation. Hotels cost more, but the city buzzes with outdoor concerts and late-night dining.
September and October might be ideal. The sea stays warm from summer heating, crowds thin out, and temperatures settle around 26°C. Restaurants offer seasonal menus featuring local harvests.
Winter isn't beach weather, but it's not unpleasant either. Temperatures hover around 15°C, museums stay open, and you'll have the city mostly to yourself. Many beach restaurants close, but the historic center maintains its rhythm.
