Weather in Cagliari in July

Prime time. If you get to pick your dates, July is the one. Highs average 27.6 °C, lows 23.4 °C, and rain falls on 1 days — nothing in the month is working against you.

July ranks 2 of 12 in Cagliari. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 4.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 32.9 °C and the coldest night fell to 19.4 °C.

July is dependably dry, and that reliability is the point: across the twenty years measured, the wettest July on record still only managed 13 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Julys brought 10 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 13.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 71%.

How July sits in the year

Temperatures hold steady either side: 24.3 °C in June, 27.6 here, 28.2 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Cagliari's year: 14.7 hours of daylight, losing 0.6 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 24.6 °C in July — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Cagliari versus nearby

If Cagliari is one option among several, the nearby comparison is worth making. Palermo is the weaker option in July — 4.6 °C warmer, 1 day more rain. Rome is the weaker option in July — 5.6 °C warmer, 3 days more rain.

So: July is effectively as good as it gets here — 1 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
