Corsica Climate and Weather
Corsica features a Mediterranean climate that is characterised by hot, dry summers and mild, wet winters. The north of the island is hotter than the south, and the east wetter than the west. The weather is influenced by the winds and the temperature is moderated by the mountains. Average summer daytime temperatures reach around 77F (25C) and can climb to as high as 95F (35C) in July and August. The inland mountainous areas are much colder in the winter than the coast and, although frost is rare on the coast, it is fairly common inland, as is snow. For this reason, some of the hiking trails are only open in the summer months. In spring and autumn there can be strong winds. Between November and May the sea is generally considered too cold for swimming.
The best time to visit Corsica is in the warmer months between June and September, as it would be a pity to miss out on the beautiful beaches and some of the famous hiking trails. However, as with most of France, Corsica can get crowded in August, which is the hottest month and the time when the French have their national holiday.
