Weather in Palermo in July
Italy · 20-year averages, July
A good month. July is a solid month to be in Palermo. Highs average 32.2 °C, lows 22.9 °C, and rain falls on 2 days — nothing in the month is working against you.
July ranks 7 of 12 in Palermo: past the worst of the year but short of May, which is the month to book if the dates are open.
Rain falls on only 2 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 32.2 °C days and 22.9 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 5 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest July day reached 39.5 °C and the coldest night fell to 17.7 °C.
July is dependably dry, and that reliability is the point: across the twenty years measured, the wettest July on record still only managed 21 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 15 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.
Wind is light at 9.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 60%.
How July sits in the year
Temperatures hold steady either side: 28.9 °C in June, 32.2 here, 32.6 in August. Nothing about the timing within the month matters much.
Daylight in July
July is at or near the longest days of Palermo's year: 14.6 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 26.5 °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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Palermo versus nearby
If Palermo is one option among several, the nearby comparison is worth making. Catania is the weaker option in July — 4.3 °C warmer, the same number of rain days. Taormina is close enough to be a coin toss — within a degree on temperature, 1 day more rain.
So: July is a compromise. May is 19 points better and is what Palermo is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
