London month by month
Plan your visit to London by month. Compare weather, crowds, events, and prices across all twelve months with historical climate data.
London's measured year splits into three bands, not four. January averages a 7°C high with 11 rain days, and the cold holds through February at 10°C and December at 9°C. April marks the turn, when highs reach 14°C and rain days drop to 8. June, July, and August cluster between 22°C and 23°C. August records the fewest rain days of any month at 7. By October, highs fall to 16°C and rain days reach their annual peak at 13.
Each of the 12 published month guides tracks what shifts between London's periods. Temperatures rise from January's 7°C to July's 23°C, but rain days follow a different pattern. August logs 7 while October reaches 13. If your trip window falls between June and August, start with those pages to compare conditions across the 22-23°C band. For spring, open April and May side by side. April averages 14°C with 8 rain days, then May rises to 18°C with 12.
October tends to be London's wettest month at 13 rain days, and March matches May at 12. November drops to 11°C with 11 rain days, a combination that likely feels rawer than the numbers alone suggest.
August is London's most decisive month, pairing the year's joint-highest temperature at 23°C with its fewest rain days at 7.
