Paris gets about 650 mm (roughly 26 inches) of rain a year, fairly evenly spread across the seasons, with no single month standing out as dramatically wetter than the rest. Weather here is dominated by a rotating series of Atlantic fronts, which tend to bring light-to-moderate rain rather than intense downpours, though summer can occasionally produce sharp thunderstorms after stretches of hot, humid weather. The Seine has periodically flooded parts of the city during unusually wet, prolonged winters, most notably in 1910 and more recently in 2016 and 2018, when sustained rain upstream raised river levels over several days rather than hours. Because Parisian weather can shift from clear to wet within the same day, radar imagery is a genuinely practical tool for deciding whether to carry an umbrella or wait out a passing shower. Météo-France operates the national weather radar network covering the greater Paris region.
