London has a reputation for rain that’s more about frequency than intensity: the city averages around 600 mm (roughly 24 inches) of precipitation a year, actually less than many other major European capitals, but it falls in frequent, often light spells spread fairly evenly through the year. Atlantic weather systems dominate, bringing a steady rotation of fronts that can shift the forecast from clear to overcast to drizzling within the same afternoon. Genuinely heavy, disruptive rainfall is less common but not rare, and when slow-moving low-pressure systems stall over the region they can bring surface water flooding to parts of the city not designed for intense short-term downpours. Because conditions can change so quickly across a single day, radar imagery is a practical way for commuters to judge whether an approaching band of rain is a passing shower or likely to linger. The UK Met Office operates the national weather radar network covering London and the surrounding region.
