Climate overview
Tokyo has a humid subtropical climate (Cfa) with four clearly defined seasons. Its location on the Pacific coast of Honshu means summers are hot and humid, while winters are cool, dry and sunny thanks to winds blowing off the Asian mainland and over Japan's mountains.
Average highs range from 10°C in January to 31°C in August. Annual rainfall is high, at about 1,530 mm, and it falls mainly in two periods: the early-summer rainy season, called tsuyu, in June and July, and the typhoon season from late summer into autumn. September is often the wettest month.
Köppen classification: Cfa — humid subtropical
Tokyo through the seasons
Winter
December – FebruaryWinters are cool and bright, with highs of 10–12°C and lows of 2–4°C. Skies are often clear and dry — January humidity averages about 50%. Snow falls occasionally but rarely lasts more than a day or two in the city.
Spring
March – MaySpring warms from 14°C in March to 23°C in May. Cherry blossoms usually peak in late March or early April, one of the most celebrated moments of the year. Rain becomes more frequent through spring.
Summer
June – AugustTsuyu, the rainy season, usually runs from early June to mid-July with frequent drizzle and grey skies. Afterwards summer turns hot and very humid, with highs of 30–31°C, warm nights around 25°C and a heat index that often exceeds 35°C.
Autumn
September – NovemberSeptember is still hot and is the peak of typhoon season, with the year's highest rainfall at about 235 mm. October and November bring cooler, clearer weather, and autumn leaves typically colour the city's parks in late November.
What makes Tokyo's weather distinctive
Typhoons are Tokyo's most significant weather hazard. Most pass by between August and October, bringing strong winds and heavy rain for a day or two; trains may be suspended and flights cancelled. The Japan Meteorological Agency issues detailed warnings, and the city's infrastructure is well prepared.
Summer heat is the other main concern. Combined with high humidity, Tokyo's urban heat island makes July and August uncomfortable, and heatstroke alerts are common. Japan's dense, air-conditioned public transport and shops offer welcome relief.
Best time to visit Tokyo
March to May and October to November are the best times to visit Tokyo. Spring brings cherry blossoms and mild weather, while autumn offers clear skies, comfortable temperatures of 17–22°C and colourful foliage. Summer is hot and humid, and winter is cold but sunny and crisp — good for clear views of Mount Fuji.
What to pack
- Light, breathable clothing and a small towel for summer humidity
- A compact umbrella for tsuyu and autumn showers
- A warm coat for winter mornings and evenings
- Layers for spring and autumn, when temperatures vary through the day
- Comfortable shoes — you will walk a lot between stations
