Sophia Antipolis - Climate
The French Riviera has an exceptional micro-climate. This area is protected from the bad weather by the Massif Estérel and the Alps.
This area is famous for its long, hot summers and mild winters. In January, the temperatures usually fall between 6 and 13 degrees Celsius (43 and 55 degrees Fahrenheit), while in August they range from 20 to 30 degrees Celsius (68 and 84 degrees Fahrenheit). On the coast, sea breezes keep the temperature cool enough to need a light jacket on spring evenings.
Be careful when it rains in November and March! It is said that the annual quantity of rain in Nice and Britanny is the same, but in Nice all the rain comes in less than a week!
So congratulations for choosing this idyllic place with such a delightful climate!
The only times you can have an “extreme climate” in the South of France, is in April. If you decide to go skiing in the Alps (one hour from Valbonne) in the morning, you have to take warm clothes. But then you can go swimming in the Mediterranean sea in the afternoon and it's warm!
