What May is like in Tokyo
Warm and increasingly humid. Late May can see early tsuyu (rainy season) moisture moving up from the south, and UV climbs fast.
These figures are long-term averages, not a forecast — for today's actual conditions and the week ahead, check the live Tokyo weather forecast. Averages are useful for planning travel, events or what to pack, but any single May can run warmer, cooler, wetter or drier than the long-term normal.
