Comprehensive Guide to Understanding and Managing Summer Heat and Humidity in Nagoya, Japan

Nagoya, located in central Japan, experiences a hot and humid summer due to its subtropical climate. Summers in Nagoya typically last from late June to early September, with July and August being the peak months for heat and humidity. Below is a detailed guide to help you understand and navigate the summer conditions in Nagoya.

1. Typical Weather Conditions in Nagoya During Summer

  • Temperature: Average daytime highs range from 30ยฐC to 35ยฐC (86ยฐF to 95ยฐF), with occasional heatwaves pushing temperatures above 37ยฐC (98.6ยฐF). Nighttime lows hover around 24ยฐC to 27ยฐC (75ยฐF to 81ยฐF), offering little relief from the heat.
