The south of France has a warmer climate than the rest of the country in general, particularly in the summer. This is why this region, commonly known as le Midi, attracts so many celebrities and wealthy travelers who can afford to occupy the shores of Corsica, Aquitaine and Auvergne. This climate is often described as Mediterranean, which is pretty accurate considering that this region is near Italy, Spain, the Atlantic Ocean and the Mediterranean Sea.
Summers are still somewhat warm in northern France, though the temperature is not as nice for coastal dwellers as it is in the south of France. Being that northern France is buttressed against Belgium it maintains temperatures that can still be a bit chilly, but acceptable as European summer weather goes. According to the BBC, the weather in northern France is a tad warmer than it is in southern Britain during the summer.
Central France is known for its rainfall, which is most apparent during the summer, especially in August. It tends to be warmer in central France than in many of the country's other regions during the summer. The heat, combined with the rainfall, can produce muggy, humid conditions. The temperature typically hovers around the high 60s and low 70s during the summer.
France has a lot of mountains and mountain ranges, including the Pyrenees, Vosges and the Alps. Naturally, these regions typically comprise colder, windier weather, even in the summertime. They are also predisposed to rain and thunderstorms, though these will usually be complemented by colder climates.
Aside from central France and a few of the mountain regions, France tends to be a relatively dry country during the summer months. Many areas, such as Bordeaux, Nice and Montpellier, experience their driest times during July, while others, such as Paris and Strasbourg, typically receive their heaviest rains during this time.
