Albeit in a temperate zone, in France there are different climates: oceanic in the west and northern coast, transitional between oceanic and continental in Paris and the central regions, continental in the eastern regions, and Mediterranean in southern coastal regions. In addition, there are of course the mountainous regions, with a colder climate.

On the Atlantic coast, the climate is generally cool and wet, rainy and windy all year round, but especially in autumn and winter.
In the north, the coasts of the English Channel are generally colder than the western Atlantic coasts. In these areas (Upper and Lower Normandy, see Mont Saint-Michel), the weather is dull and wet, cool but not cold in winter (except when it's reached by the currents from Eastern Europe), and cool in summer: the average temperature in Dunkirk goes from 41 °F in January, to 65 °F in August.
Further west, in Brittany, the climate is even more influenced by the Atlantic Ocean: so in Brest the average temperature increases in January and February to 44 °F, while in July and August it doesn't go above 62 °F. The islands of Brittany (Bréhat, Belle Île, Ouessant) have a very mild climate: the temperature almost never drops below freezing, so that palm trees and tropical species can grow; in summer, however, it never reaches 85 °F.
Here are the average temperatures of Brest.

Moving south along the Atlantic coast, summer becomes gradually milder: in Nantes the average temperature in July reaches 65.5 °F. Further south, summer is quite warm, since the south-central area of France is often protected by the Azores Anticyclone. Hence, in Bordeaux, Aquitaine, the average temperature goes from 43.5 °F in January, to 70.5 °F in July and August. During summer this area can experience cool and rainy days caused by the Atlantic fronts, but also hot and sunny days, with temperatures around 91/93 °F and above. In autumn and winter, as well as rains, there may be strong winds, but this region is also exposed to the cold wind from the north-east, the (Bise), so it is more prone to frost than Brittany.

The region of Paris is located between the cool area of the Atlantic coasts, and the more continental areas on the border with Germany. The average temperatures are quite cool: in January the daily average is 40.5 °F, while in July it's 68.5 °F. However, Paris is located in a continental area, that can be heated in summer by the Azores High, which brings subtropical air masses, therefore it can be hot in summer, with temperatures about 90/91 °F or above; in addition, during winter the city is exposed to cold spells from Eastern Europe, so that there may be some icy or snowy days, with night temperatures about 18/21 °F, or even below.
Anyway, usually the westerlies prevail, so the weather is unstable, with many wet and rainy days, cool in summer and mild in winter. The most intense Atlantic low pressure areas, can bring strong winds from the ocean, especially in winter.

In Le Mans, which hosts the famous car race of the "24 Hours", the climate is similar to that of Paris.

North-east of Paris, in the region on the border with Belgium (Nord-Pas de Calais), the climate, apart from the coastal area of which we have already spoken, is similar to that of Paris but a bit cooler: in Lille, the average temperature goes from 36.5 °F in January, to 64.5 °F in July.

The eastern regions, on the border with Germany, have a more continental climate. In Nancy, Lorraine, the average goes from 34 °F in January, to 64.5 °F in July. Alsace, lying on the Rhine corridor, has a "German" climate, characterized by cold and gray winters, accompanied by frequent snowfalls, although generally not abundant, and warm summers, sometimes hot, with some chance of thunderstorms. Even in Strasbourg, the average temperature in January is 35 °F, while that of July is 67 °F. Further south, in Mulhouse, which is sheltered from the mild westerlies by the Vosges, the average in January is around freezing and snowfalls are frequent.

In the mountainous regions (Alps, Pyrenees, Jura, Massif Central) the climate varies mainly according to altitude: it becomes obviously colder with increasing altitude. In summer, there are frequent thunderstorms in the afternoon. In Chamonix (Haute-Savoie, north of Mont Blanc), the average temperature in January and July are respectively 28 °F and 61 °F; in Lus la Croix-Haute, in the Isère Department (western side), they are respectively 30 °F and 61.5 °F.

The regions of France bordering the Mediterranean Sea (south coast and Corsica) have a Mediterranean climate, with mild, rainy winters and hot, dry summers. It's better, however, to distinguish between the different zones.
The sheltered areas like the Côte d'Azur (see Saint Tropez, Cannes, Nice) have a particularly mild climate, similar to the Italian Riviera. Generally, as is the case in Italy, the rainiest season is autumn, followed by winter.

On the other hand, west of this region there's an annoying wind, called Mistral, which often blows in the Rhone Valley, south of Valence, while the Tramontane blows over Languedoc-Roussillon. These dry and cold winds blow for about one hundred days per year, and can easily reach 50/60 mph. So, cities like Nimes, Arles, Avignon, Marseille have an average winter temperature a bit lower than the Cote d'Azur, around 43/45 °F, instead of 46/48 °F, and besides, they are exposed to sudden drops in temperature, and even frosts during the cold season. However, summer is hot and sunny here as well, because cold winds usually give a break in the warm season.
Even the sea temperature, in this part of the coast is slightly cooler than in the French Riviera (about 2/4 degrees Fahrenheit).
The western area of the Mediterranean coast, overlooking the Gulf of Lion, has mild winters, but is also exposed to the north-west winds, which are channeled through the so-called gates of Carcassonne. In Perpignan, the average temperature is 47.5 °F in January and 75 °F in July. Further to the north-west and away from the sea, in Toulouse, the temperature is a bit lower, ranging from 43 °F in January to 71.5 °F in July.
The island of Corsica has a Mediterranean climate on the coasts, with mild and wet winters, and warm or hot and sunny summers, even though it's exposed to the Mistal, which can be strong, especially on the western and southern part of the island. In the interior, there are steep and high mountains, so that the landscape becomes quickly greener, and the weather gets colder with increasing altitude, up to the higher altitudes, where there's a typical mountain climate, and winters are characterized by abundant snowfall.
Here are the average temperatures of Ajaccio, the main city, located on the west coast.

When to go

The best time to visit Paris goes from late spring (mid-May to late June) to early autumn (September). The mid-summer period (July-August) is a good time, but sometimes it can get hot. The same can be said in general for all the inland areas of France.

To visit Brittany, Normandy and the Atlantic coastal areas, the best time is the summer (June to August).

To visit the Mediterranean regions, the best times are spring and autumn, especially the months of May and June and the first half of September (in the second half of September the temperature is still pleasant, but the rains may become abundant, even with the risk of floods). In mid-summer (July-August), however, the heat is usually bearable, because it's humid but also tempered by breezes, at least along the coast.

For swimming and sunbathing, the Mediterranean Sea (where the best time is July and August) is preferable to the Atlantic Ocean (especially the northern part of the latter, which is cooler), because the temperatures of both the air and the sea are higher, and sunshine is also more frequent.

For skiing, late winter and early spring (February-March) are preferable, because the days are longer than in December and January. In some locations at high altitudes, there are also summer ski resorts.

To visit the mountain regions, summer is a good time, even though there may be some thunderstorms in the afternoon.

What to pack

In winter: warm clothing, sweater, coat, rain jacket or umbrella; scarf, hat and gloves for the colder north-central area and the mountains.

In summer: for Brittany and Normandy, clothes for spring and autumn, t-shirt for hot days, jacket, raincoat or umbrella. For the rest of the country, light clothing, but also long pants, jacket and sweater for the evening and cooler days; raincoat or umbrella. For the mountains, hiking shoes, sunscreen and sunglasses.
