Traders assign the highest probability (48.5%) to a 24°C minimum in Tokyo on August 14, followed by 23°C (24%), reflecting consensus around the long-term August climatological average low of roughly 24°C. Official forecasts from sources such as the Japan Meteorological Agency and global models show nighttime temperatures settling near 23–24°C under typical late-summer conditions: a strong Pacific high maintaining warm, humid air with scattered showers or thunderstorms that can limit radiative cooling. No major cold fronts, typhoons, or anomalous blocking patterns are indicated in the latest runs, keeping the distribution tightly centered on 23–25°C. Higher probabilities for 25°C or above would require clearer skies and stronger subsidence, while sub-23°C outcomes remain unlikely absent an unexpected northerly surge. Updated model guidance and official minimum readings the morning of August 14 will serve as the primary near-term catalysts.
