Your July weather guide
Yes, July is a good month for Italy if you want warm seas and reliably hot weather, but it is less comfortable for long days walking around cities. Country averages reach 28°C by day and 20°C at night, with the sea at 25°C. The islands suit travellers who prioritise dry weather, while northern destinations have more rainy days. Plan active time for mornings and leave room for a break from the midday heat.

16 destinations shownClimate averages, not a forecast.
Daytime highs across Italy in July run from 26.6°C (Positano) to 31.7°C (Sicily). In Sicily about 100% of July days reach 25°C. Nights average 20.3°C; the coldest 10% of nights in Positano fall to 19°C or below.
Expect around 6 rainy days (1 mm or more) in July, with Sardinia the driest (1 days) and Verona the wettest (12 days). The wettest July at Sicily between 1991 and 2020 was 2006 with 64 mm; the driest was 2001 with 0 mm.
The sea averages 25.1°C around Italy in July - warmest at Naples (25.5°C). That is comfortable for swimming.
Around 10.9 hours of sunshine a day on average, out of 14.3 hours of daylight (sunshine estimated from cloud cover).
July is the 2nd warmest month of the twelve in Italy. It is 2.8°C warmer than June and 0.2°C warmer in August. The hottest month here is August (29°C) and the coolest January (10°C).
Based on the averages: summer clothes for the day; a light waterproof for the odd shower; swimwear - the sea is 25°C.
Within 1.5°C of Italy's July daytime average: Hong Kong (30°C, sea 28°C), Playa del Carmen (30°C, sea 29°C), Cancun (30°C, sea 29°C), Chiang Mai (30°C), Koh Samui (30°C, sea 29°C). See the full ranking for July.
Sardinia and Sicily are strong choices if avoiding rain matters most. Sardinia averages 1 rainy day in July, compared with 2 in Sicily, so outdoor plans are less likely to need rearranging than in the north. The catch is the heat: Sicily is the hottest destination listed at 32°C by day, while Sardinia reaches 30°C. Their seas average 25°C and 24°C respectively, making swimming an appealing part of the day. Puglia offers a less hot daytime average of 28°C, but its 22°C nights mean evenings remain warm. Pack light clothing and make shade part of your plans rather than an afterthought.
Rome and Florence both average 30°C during the day, so July suits city travellers who are happy to start early and pause when the heat builds. Their average nights are cooler at 19°C and 18°C, making evenings a better time for being outside than the middle of the day. Both have 4 rainy days on average, so heat is the more persistent planning concern. Naples is slightly less hot by day at 29°C, though nights stay warmer at 21°C. If you want to combine time in the city with swimming, its 26°C sea average is warmer than Sardinia's.
Head north for a different balance of heat and rain, not for a reliably cool July. Milan and Verona both average 29°C by day, while Lake Garda reaches 28°C. Rain is more of a consideration here: Verona averages 12 rainy days, Lake Garda 10 and Milan 9. That makes flexible outdoor plans and a light waterproof sensible, even though summer clothing will still get plenty of use. Positano has the lowest daytime average among the destinations listed, at 27°C, but that is still warm rather than cool. If heat is your main concern, your daily schedule matters as well as your destination.

Italy averages 28°C by day in July, compared with London's 22°C. Expect a noticeably hotter holiday, particularly in Sicily at 32°C. For walking-heavy days, plan around the heat rather than assuming your usual London summer routine will feel comfortable.
July is a good choice for travellers who prefer warm water, with Italy's sea averaging 25°C. Naples reaches 26°C, while Sardinia averages 24°C. Sicily, Puglia and Taormina sit at 25°C, so swimming is a reasonable priority when choosing where to stay.
Light clothing should cover much of your trip, with nights averaging 20°C nationally. A light layer is sensible for Florence and Milan, where nights average 18°C. Sicily and Puglia stay warmer at 22°C, so breathable nightwear is useful.
