Marseille weather is mild in winter - the average temperature in February are usually from 4 to 14 degrees Celsius (39 to 57 F). What makes a day really cold sometimes is the wind called the Mistral. It is a very cold, strong wind that comes from up north and travels down the Rhone Valley. Although it is cold and very strong, it is the wind that clears the sky and bring sunny weather. It is very strong everywhere around the Rhone delta (Arles, Salon de Provence), down to Marseille. But all this is true all year round, the Mistral has no favorite season, it blows all year round. Of course February is a winter month, so don't expect very warm and sunny weather throughout the month. This winter people say December and January will be colder, and February milder...
