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.
| Typical daytime high | 19°C (66°F) |
|---|---|
| Typical night low | 9°C (48°F) |
| Day–night swing | 10°C (18°F) |
| Rain risk | High |
| Ground | Tarmac and pavement |
| Sun exposure | High, little natural shade |
Assume rain. A packable shell in your bag costs nothing to carry and saves the weekend; a "cute" jacket that soaks through ruins two days.
Everything below follows from those numbers.
