Forecasts from the Japan Meteorological Agency and ensemble models indicate an overnight low near 26°C in Tokyo on August 1, 2026, reflecting a persistent warm, humid air mass with limited nocturnal cooling under partly cloudy skies. This above-normal warmth, exceeding the historical August average of 24–25°C, underpins the 97.5% market-implied probability for exactly 26°C as the daily minimum recorded at official stations. Traders weigh the consistency of current guidance against the possibility of stronger radiative cooling from clearer skies or an unexpected frontal passage, which could produce a 25°C or lower reading, though such shifts remain unlikely before resolution.
