What to wear to Nice Carnival: Nice sits at 14°C (57°F) by day and 7°C (45°F) at night in February, on city streets, with a moderate chance of rain. That means thermal layers under a statement outer layer, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans carnival, costume and parade, so a full costume is the norm rather than the exception.
