Climate in Tokyo, Japan

Tokyo, Japan has a humid subtropical climate. The annual average temperature is about 19.5°C, with around 954 hours of sunshine; the national rainfall baseline is roughly 1500 mm across 168 rainy days a year. The warmest month is Jul (highs near 30.1°C) and the coldest is Jan (lows near 8.9°C). These are deterministic planning estimates, not a forecast or measured station data. Temperature and sunshine follow the city's latitude; rainfall and the climate zone come from a country-level baseline that every city in the country shares (refined by region in the United States, Canada and Australia), so they do not show local differences. Check current conditions with an official meteorological service before travel.

Climate zone

Köppen-style classification derived deterministically from latitude and a country-level precipitation baseline.

Climate zone

Tokyo is classified as Humid Subtropical. The classification combines the city’s own temperature range, which follows its latitude, with a rainfall pattern taken at country level for Japan — so cities in the same country usually share a zone.
