Recent JMA seasonal outlooks for summer 2026 highlight above-normal temperatures across Japan driven by a strengthened Pacific High, sustaining the typical August pattern of muggy nights with minima near 24–26°C in Tokyo. Historical climatology shows average overnight lows of 24–25°C, and short-range guidance indicates no significant frontal passages or radiative cooling episodes expected to push the August 2 minimum below 24°C or above 26°C. These factors concentrate trader consensus on 25°C as the modal outcome, with modest probability mass on adjacent values reflecting minor model spread in humidity and cloud cover that could nudge the daily minimum by 1°C.
