What to wear to Cologne Carnival: Cologne sits at 7°C (45°F) by day and 2°C (36°F) at night in February, on city streets, with a high 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.
| Typical daytime high | 7°C (45°F) |
|---|---|
| Typical night low | 2°C (36°F) |
| Day–night swing | 5°C (9°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.
