Nice in October

May through June gives you warm weather without the crowds. September and October are golden—still swimmable but less chaotic. April can be lovely but unpredictable. July and August mean peak prices, packed beaches, and 30°C+ heat. Winter surprises people with its mildness—December averages 13°C and you'll find deals on hotels. But some restaurants close, and that famous light isn't quite the same. The Carnival in February brings energy but also crowds. Spring brings the film festival crowd to nearby Cannes, which affects Nice too.
