London hourly weather

London hour-by-hour, explained

London's coastal position means conditions can shift quickly, especially when a southerly buster rolls up the coast on a hot summer afternoon. Our hourly forecast breaks the next 24 hours into individual slices so you know when the rain arrives, when the wind picks up, and when to grab a jacket.
