Current forecasts from the Japan Meteorological Agency and seasonal models indicate an overnight low near 24–25°C for Tokyo on August 10, consistent with August climatology where average minima reach about 24°C amid persistent Pacific high pressure and high humidity that limits nocturnal radiative cooling. Urban heat island effects and potential cloud cover further moderate temperature drops, while above-normal summer 2026 outlooks introduce slight upward bias without altering the tight distribution. Trader consensus at 54.5% for 24°C and 37% for 25°C captures model consensus around these thresholds, with lower probabilities for outliers reflecting limited scope for significant cooling or heat advection in the short term before resolution.
