Sunny Nice
The weather in southern France, Provence, and the French Riviera is some of the best in Europe. Mild and Mediterranean, the climate in the region is ideal for those that like it hot.
Average temperatures on the French Riviera hover around 15°C (59°F). In the winter, southern France rarely gets colder than 5°C (41°F), and in the summer temperatures can reach a high of 40°C (104°F).
Winters in southern France are mild, although rain and wind can be persistent in some years. Summers are hot, and the weather can often be sweltering.
If you want a more balanced climate for your visit, consider traveling in the late spring or early autumn. April, May, September, and October are great months in Provence, and the crowds are much lower than in the summer months.
