The best time to visit Nice is in the shoulder season of September to October, or from mid-March to April. You can take advantage of the Mediterranean weather all year-round, however. Average high temperatures range from the mid-50s in the winter to the low 80s in the summer, and the city sees an average of 300 sunny days per year. However, despite the sun's warm rays, many recommend packing some extra layers of clothing, even in the summer, since winds sweeping north off the Mediterranean Sea can be slightly chilly.
