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.
