Weather in Tokyo in July

Shoulder season. July sits in between. You will get good days and you will lose some. The heat itself is manageable at 29.5 °C, but 83% humidity is what you will actually feel.

July ranks 9 of 12 in Tokyo: past the worst of the year but short of May, which is the month to book if the dates are open.

Rain on 15 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 14 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 36.3 °C and the coldest night fell to 16 °C, and the wettest single day dropped 103 mm — roughly 68% of the month's rain in one day.

July is moderately variable: 28 mm in the driest year against 347 mm in the wettest, around an average of 152 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 8.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 25.8 °C in June, 29.5 here, 31 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Tokyo's year: 14.4 hours of daylight, losing 0.5 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 25.8 °C in July — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Tokyo versus nearby

If Tokyo is one option among several, the nearby comparison is worth making. Utsunomiya is close enough to be a coin toss — within a degree on temperature, 4 days more rain. Hamamatsu is close enough to be a coin toss — 2.9 °C cooler, 2 days more rain.

So: July works, with May the better month by 18 points if the dates can move. If they cannot, nothing here should stop you booking.
