What to wear to Mardi Gras New Orleans: New Orleans sits at 19°C (66°F) by day and 9°C (48°F) at night in February, on city streets, with a high chance of rain. That means a light base with one warm layer you can carry, 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.
