As a result Nice has some nice mild weather throughout the year, with temperatures in the mid 70s in the summer and the high 50s in the winter. Thats the good news. Whilst boasting variously 200 - 250 days of sunshine a year, that still leaves at least 100 days unnaccounted for. It does rain too. November is historically the wettest month of the year, though cloudy and rainy days can confidently be forecast on some occasions all year round. Nice is especially difficult to predict because of its hills behind, so it can be cloudy inland and at the same time sunny along the coast.
