Weather in Nice in July

July is a good time to visit Nice if you want hot days and a sea warm enough for swimming. Average daytime highs are around 27°C, nights stay near 20°C and the sea averages roughly 24°C. The catch is that warm evenings offer limited relief from the daytime heat, and rain is still possible. For a UK traveller, it suits a summer holiday built around swimming and a slower pace at midday.

Expect reliable warmth, not constant extreme heat

Days reach 25°C on 85% of July days, so pack mainly for warm weather rather than hoping for an occasional hot afternoon. Around 10% of days reach 30°C, making hotter spells a possibility without that being the everyday norm. With humidity averaging 73%, the warmth can feel close, particularly when you are active. Light, loose clothing and shade breaks make more sense than a packed midday schedule. Use mornings for longer walks and leave room to slow down in the afternoon. Nights average around 20°C, so check the cooling arrangements where you stay if warm bedrooms tend to disrupt your sleep.

Plenty of sun and swimmable seas, with some showers

July brings about 9.9 hours of sunshine within 14.9 hours of daylight, giving you plenty of flexibility to spend time outdoors without doing everything at midday. Sunscreen, sunglasses and a hat deserve space in your bag, alongside a light waterproof: about 6 days have measurable rain, so a completely dry stay is not guaranteed. Keep outdoor plans flexible rather than treating every day as settled. The sea averages 23.9°C, comfortably within the swimming range, although July temperatures vary from 22°C to 26°C between years. That makes July a strong choice if swimming matters to your holiday. If you prefer cooler conditions for being on the move all day, the combination of sunshine, warmth and humidity is the main drawback.
