Nice Weather in September

September by the sea

September still feels warm in Nice, with daytime highs around 23°C and mild evenings. The sea and beach days remain appealing, while cooler conditions make walks through Vieux Nice and up Castle Hill more comfortable than in August. There's about eight hours of sun a day, but rain falls on around seven days, so a shower may interrupt an outdoor plan.

August is hotter and drier, with highs of 26°C and less rain. September's extra showers are worth keeping in mind if you're planning a long coastal walk. For couples who prefer exploring without peak summer heat, this is a comfortable month for the Promenade des Anglais and old-town strolls.

Events and local life

The European Heritage Days usually take place in September. They open historic sites and buildings across France, and Nice is a good place to look for local visits and special access. The exact dates and programme change each year.

French school holidays have ended, so family crowds tend to thin after the summer rush. Nice is still in its main visitor season, though, and the beaches and central streets can remain busy. Prices often ease from August, but don't expect the quieter, cheaper feel of the low season.

A good time to explore

September sits among Nice's best months, but it's not reliably dry. October brings more rain and cooler days, while September's mix of sun and showers suits museum visits as well as time outside. If rain arrives, the Marc Chagall National Museum offers an easy change of pace from the seafront.

For a local food stop, try socca, a thin chickpea-flour pancake often served in Vieux Nice. Eat it fresh from the oven; it's less satisfying once it cools. Then take the tram back towards the Promenade if your feet are ready for a break.
