As in any country, weather depends on your region, but, generally, France enjoys a temperate climate with four regular seasons, little rain, and low humidity.
The oceanic climate, prevailing in the western parts of the country, is one of small temperature range. Ample rainfall, cool summers, and cool but seldom very cold winters. The western coast is similar to that of the Pacific Northwest—wet and temperate; it rains more in the Brittany region than other parts of the country.
The continental (transition) climate, found over much of eastern and central France (along its western border with the rest Europe), is known for warmer summers and colder winters than areas farther west. Expect ample rainfall and snowy winters, especially at higher elevations.
The Mediterranean climate, widespread throughout the south of France (except in the mountainous southwest), is one of cool winters, hot summers, and low rainfall.
Excluding Paris and Versailles in the Île-de-France region, expats and retirees take a special interest in the areas around the Mediterranean Coast where they find the more popular Mediterranean climate of, for example, France’s Iberian neighbors—much warmer on average. This part of France gets the highest number of sunshine days per year, and also less precipitation.
And then there’s the Cote d’Azur—the French Riviera—the nation’s resort gem. Boasting Mediterranean temperatures and crystalline seas, the South of France is where you go for beach fun, beautiful people, and breathtaking yachts.
Central France is defined by untrammeled, rolling countryside and majestic mountain ranges—which are sunny in the summer and snowy in the winter.
France is a popular destination all year round, but summer is the peak season (from June to August). During this period, it is generally sunny and warm across the whole country… but this would also be the time to avoid if you’re not fond of tourist crowds.
Recommended dress code for French weather: light, breathable clothing in Mediterranean summers, jacket or sweater for Mediterranean winters, and waterproof winter gear for the mountain side all year long.
