What to wear to Notting Hill Carnival: London sits at 22°C (72°F) by day and 15°C (59°F) at night in August, on city streets, with a moderate 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.
