Weather in London
London weather is a personality. The grey isn't sad — it's constant. The rare sunny day is an event. Locals dress in layers regardless of the forecast, carry a jacket from June through September, and treat any temperature above 20° as a heatwave. The city has its own relationship with drizzle: not quite rain, not quite dry, entirely London.
Best time to visit
May to September for warmth. October for crisp, clear days. December for atmosphere.
What to know
London rain rarely arrives in heavy downpours — it's persistent, light, and often invisible on a radar. Wind chill makes mild days feel cold. Always check feels-like, not just temperature.
"The most useful London weather question isn't 'will it rain?' — it's 'when is my window?' There's almost always one."
