Tokyo July Weather & What to Wear (2026): Rainy Season, Heat & Sunset Guide
Tokyo Mate
July is the month when Tokyo's rainy season and midsummer heat both happen at the same time.
Cloudy, rainy days continue until around July 19, but the moment the rainy season ends, full-on summer heat above 30°C begins.
If you're planning a July trip to Tokyo to avoid the rainy season, late July is a good time to go. That said, you'll definitely need to prepare for strong UV, high humidity, and serious summer heat.
This guide pulls together the end of Tokyo's July rainy season, the weather differences across early, mid, and late month, what to wear for the heat, and sunset times all in one place — based on Japan Meteorological Agency normals (1991–2020) and National Astronomical Observatory of Japan (NAOJ) 2026 official data.

The normal end date of the rainy season for Tokyo and the wider Kanto region is around July 19.

July Rainfall Pattern
July's total rainfall (about 156mm) is slightly less than June's (about 168mm), but early and mid-July see a lot of short, heavy downpours, so it often feels more unpleasant than the numbers suggest.
By late July the number of rainy days drops, and the rain mostly comes as brief afternoon showers that pass quickly.
| July Week | Rainfall | Rainy Days |
|---|---|---|
| Week 1 (1–7) | ~42mm | 4–5 rainy days |
| Week 2 (8–14) | ~35mm | 3–4 rainy days |
| Week 3 (15–21) | ~30mm | 2–3 rainy days |
| Week 4 (22–31) | ~41mm | 2–3 rainy days |
(Source: JMA 1991–2020 normals, Tokyo station 47662 / July monthly rainfall ~156mm, average humidity 76%)
Early & mid-July: when the rainy season is strongest
Early and mid-July is the stretch when cloudy, rainy days keep coming.
Humidity is high too, so the heat feels intense. It's better to plan your itinerary around indoor observation decks, shopping malls, and art museums rather than outdoor sights.
Late July: the rainy season ends
Once the rainy season ends, the Pacific high-pressure system moves in and clear days increase quickly.
Daytime highs above 30°C become common, and with high humidity, the apparent temperature climbs to around 35°C on plenty of days. From this point on, sun protection and staying hydrated are essential.

Tokyo Early & Mid-July Weather: Temperature and Humidity
Early July (1–10): Late Rainy Season, Heat and Rain Overlap
Early July is when the rainy season is still going.
Daytime highs climb to 28–29°C and morning lows stay around 21–22°C, so the heat doesn't ease up much even at night.
On rainy days, humidity (monthly average 76%) climbs higher too, so the apparent temperature feels much hotter than the actual reading on many days.
| Date | Avg. High | Avg. Low |
|---|---|---|
| July 1 | 28.0°C | 20.7°C |
| July 5 | 28.6°C | 21.2°C |
| July 10 | 29.2°C | 21.8°C |
(Source: JMA 1991–2020 normals, Tokyo station 47662)
Mid-July (11–20): Around the End of the Rainy Season, Temperatures Rise Fast
Mid-July is the turning point where the rainy season winds down.
Daytime temperatures that were at early-month levels (28–29°C) climb quickly to 29–30°C in the second half of mid-month, and from around the 19th, days above 30°C start to appear in earnest.
In July the daily temperature range narrows to around 7°C, so the heat lingers into the night on more days, and nights where it's hard to sleep without air conditioning start to appear.
| Date | Avg. High | Avg. Low |
|---|---|---|
| July 11 | 29.3°C | 21.9°C |
| July 15 | 29.8°C | 22.3°C |
| July 20 | 30.2°C | 22.7°C |

Tokyo Late July Weather: Heat Wave and Fireworks Season
Late July (21–31): Full Summer, the Heat Wave Begins
Late July, after the rainy season ends, is when Tokyo's full-on summer heat begins.
Daytime highs climb to 30–31°C and morning lows rise to around 23–24°C, so the number of days when the heat lingers into the night increases.
Even after the rainy season ends, there are days when a sudden shower pours down in the late afternoon, so it's a good idea to keep carrying a folding umbrella. With high humidity, there are many days when the heat feels intense.
| Date | Avg. High | Avg. Low |
|---|---|---|
| July 21 | 30.3°C | 22.8°C |
| July 25 | 30.9°C | 23.3°C |
| July 31 | 31.6°C | 23.8°C |

Fireworks Season
From late July, large fireworks festivals are held all over Tokyo. The Sumida River Fireworks Festival (隅田川花火大会) is the largest in Tokyo and is held around the last Saturday of July. When watching outdoors, preparing for the heat and staying hydrated are essential.

Early & Mid-July Outfits (During the Rainy Season)
Early and mid-July is a time when you have to prepare for both heat and rain.
Short sleeves are the baseline, but you also need to factor in sudden showers and indoor air conditioning. Humidity is high so sweat doesn't dry easily, which makes breathable, quick-drying fabrics the most comfortable choice.
▶ Recommended combo: short sleeves + waterproof jacket or thin cardigan
- Recommended fabrics: quick-drying materials like polyester and linen
- Umbrella: a sturdy one is recommended (small folding umbrellas often flip inside out in strong wind and rain)
- Shoes: water-resistant sneakers or sandals (leather not recommended)
- For indoor air conditioning: one thin cardigan
Late July Outfits (After the Rainy Season Ends)
From late July, after the rainy season ends, full-on summer heat begins. Short sleeves are the baseline, and during the day the strong sun and high humidity make sun protection essential. Without a hat and sunglasses, long stretches of outdoor activity will wear you out fast.
▶ Recommended combo: short sleeves + SPF 50+ sunscreen + sunglasses + hat
- Good to bring: a small handheld fan, cooling spray
- Bag: a light waterproof tote (for afternoon showers)
Outfit Summary by Period
| Period | Daytime Temp | Outfit · Key Items |
|---|---|---|
| Early & mid-July | 28–30°C | Short sleeves + waterproof jacket Sturdy umbrella, indoor cardigan |
| Late July | 30–31°C | Short sleeves + sun protection Hat, sunglasses, cooling spray |
Tokyo July Sunset Times and Summer Night-View Spots
July comes after the summer solstice (June 21), so Tokyo's sunset times start to get a little earlier. Even so, the days are still long, so it's a month when you can comfortably enjoy your travel schedule into the evening.
Compared with the June 30 sunset (19:01), July 30 (18:47) is about 14 minutes earlier.
That's because the days start getting a little shorter after the solstice.
Even so, it stays light until 18:47 at the end of July, so there's plenty of room for evening sightseeing. For observation decks and night-view spots, aiming for entry after 19:00 is a good way to enjoy both the sunset glow and the night view.
| Period | Sunrise | Sunset |
|---|---|---|
| July 10 | 04:33 | 18:59 |
| July 20 | 04:40 | 18:55 |
| July 30 | 04:47 | 18:47 |

Recommended Sunset & Night-View Spots in July
① Shibuya Sky
On clear days after the rainy season ends, this is an observation deck where the summer sunset looks especially beautiful. On the rooftop, the heat feels stronger than the breeze on many days, so it's a good idea to bring water or a sports drink in advance.
➡️ View Shibuya Sky tickets on KKday
② Tokyo Skytree
During the late-July fireworks season, looking down at the hanabi from Skytree is a popular course too. Around the Sumida River Fireworks Festival dates in particular, reservations sell out very quickly.
➡️ Book Tokyo Skytree tickets on Klook
③ Roppongi Hills Observation Deck
A good amount of the viewing is indoors, making it a great place to enjoy the night view while escaping the midsummer heat.

📌 Night-View Visit Tips
In late July, outdoor observation decks stay hot at around 28°C even after the sun goes down. Be sure to bring cooling spray and water.
Tokyo in July is a month when the weather and what you need to pack change dramatically around the end of the rainy season (around July 19). If you're visiting during the rainy season, it's best to plan your itinerary around indoor spots, and if you're coming after it ends, it's important to prepare well for the heat, UV, and staying hydrated.
From late July in particular, fireworks and summer festivals get into full swing, so as long as you prepare well for the heat, it's also the season when you can enjoy Tokyo's midsummer atmosphere at its best.
