What to Wear in Tokyo in July
Packing for Tokyo in July means dressing for 28°C days and 22°C evenings. A light cotton tee with a casual overshirt works well at 28°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 22°C, a modest 6°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 13 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. For temple and religious site visits, carry a lightweight scarf or sarong to cover shoulders and knees, required at most major sites across the region.
Local tip: Temple and religious site visits require covered shoulders and knees in most of Tokyo's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.

Why is Tokyo warm in July?
Tokyo's July heat is driven by the Asian summer monsoon system, as the low-pressure cell that forms over the heated landmass draws warm, humid air from the oceans. The result is temperatures averaging 28°C with high moisture in the air. Overnight temperatures remain elevated at 22°C, as clouds and humidity prevent the earth from radiating heat away after sunset. Climate data: Open-Meteo ERA5 (1991–2020).
