A month-by-month planning table for Tokyo built on the Japan Meteorological Agency 1991-2020 normals recorded at Kitanomaru Park, Chiyoda — 30-year averages that tell you what a month is actually like, not what today happens to look like. Pick any month and get the typical high and low in both scales, how many days bring measurable rain, the humidity you will feel, and what to pack.
The pattern that surprises first-time visitors: Tokyo's winter is dry and mostly sunny — December averages about 6 rain days and 56% humidity — while summer is the sticky season, with July and August holding 74-76% humidity and highs near 31 C. Rain peaks in September and October (225-235 mm, typhoon and autumn-front season), not in June's famous tsuyu plum-rain front, and average annual snowfall is just 8 centimetres.
How to use
- Pick your travel month from the dropdown.
- Read the typical high/low (shown in C and F), rainy days and humidity, plus the packing line.
- Cross-check the full 12-month table below when your dates are flexible — November and late October combine mild days with the fewest rain days.
Frequently asked questions
When is the best time to visit Tokyo?
Late October to November and mid-March to April. November runs about 16.7/8.8 C (62/48 F) with only 8 rainy days and humidity back down to 64%; April is the mirror image at 19.4/9.8 C (67/50 F) before the humidity climbs. Cherry blossoms usually peak in late March through early April, autumn colours in mid-to-late November.
Does it snow in Tokyo?
Barely. The 1991-2020 average is 8 cm for the whole year, essentially all of it in January and February (about 4 cm each month). Snow rarely settles on streets for a full day — though even modest forecasts snarl trains, because the city almost never needs its snow equipment.
What is tsuyu, Tokyo's rainy season?
The plum-rain front that sits over Japan from early June into mid-July. June averages 12.8 rainy days and 168 mm with humidity at 75% — damp, grey and steamy, but rarely a full-day washout. July's total rain (156 mm) is actually slightly lower.
When is typhoon season in Tokyo?
August through October. September and October are Tokyo's wettest months (225 and 235 mm), because typhoons and the autumn rain front overlap — expect a few disrupted travel days, and build slack into any day trip to Mt Fuji or a flight connection in those months.
What should I wear in Tokyo in winter?
December through February runs 12/3.8 down to 9.8/1.2 C (54/39 to 50/34 F) — dry cold, often under blue sky. A warm coat plus layers covers it; thermals help on windy days. Indoors is heated, so pieces you can shed matter more than one huge parka.
How do these normals compare with a forecast?
Normals are 30-year averages — an individual month can run 2-3 C warmer or colder and rain days swing by several. Use this table to pick dates and build a packing list, then check a forecast about a week before you fly.
