August is the year's hottest month and the peak of Korean summer travel. 32°C / 90°F highs, felt-temperature 100°F+ / 38°C+ with humidity 73%. The signature event is Hakata Bay fireworks (early August, Marizon waterfront). Obon holidays (Aug 13-15) close some restaurants, drive Japanese domestic travel up, and overlap with Korean Liberation Day (Aug 15) — fare spike week. Indoor cooling refuges are essential: Canal City + Hakata Station depachika + Tenjin Underground Arcade. Late August (post-Aug 20) is the summer-tail value recovery — fares drop 20-30%, weather still hot but humidity drops.
