Japan Tokyo Weather in July — Climate Guide
July in Tokyo is Mixed
July is Mixed for Tokyo.
July in Tokyo is hot and humid. Honestly, it's not pleasant sightseeing weather — average highs of 30°C with 76% humidity push the heat index above 35°C / 95°F. But there are July-only experiences worth enduring the heat for.
July's headline is hanabi (fireworks). The Sumida River Fireworks Festival on the last Saturday of July is Tokyo's biggest, with about 20,000 fireworks lighting the sky behind Skytree. Crowds reach 900,000 — arrive before 3 PM for a good viewing spot. Renting a yukata (summer kimono) for $20-35 / ¥3,000-5,000 from Asakusa rental shops is a memorable touch.

Tokyo in July — Full Picture
July in Tokyo is hot and humid. Honestly, it's not pleasant sightseeing weather — average highs of 30°C with 76% humidity push the heat index above 35°C / 95°F. But there are July-only experiences worth enduring the heat for.
July's headline is hanabi (fireworks). The Sumida River Fireworks Festival on the last Saturday of July is Tokyo's biggest, with about 20,000 fireworks lighting the sky behind Skytree. Crowds reach 900,000 — arrive before 3 PM for a good viewing spot. Renting a yukata (summer kimono) for $20-35 / ¥3,000-5,000 from Asakusa rental shops is a memorable touch.
Practical heat tips: do outdoor activities before 10 AM or after 4 PM, and use indoor venues (shopping malls, museums) during midday. Convenience stores sell cooling sprays (hiyashi spray, $2-3 / ¥300-500) and cooling sheets that travelers swear by. By mid-July, rainy season ends and proper summer arrives, so late July sees fewer rain disruptions.
What to Wear & What to Pack
T-shirts and shorts are baseline. Sunscreen, sunglasses, and a hat are essential. Indoor AC is brutally cold — always carry a light cardigan. Linen and cotton breathe well. Pack extra T-shirts; you'll sweat through them.
