**Persistent warm, humid air and light southerly flow overnight have kept Tokyo temperatures elevated, supporting the market’s overwhelming 98.5% consensus on a 28°C minimum for August 25.** Official Japan Meteorological Agency guidance and regional model runs indicate overnight lows stabilizing near this threshold, consistent with recent nights where dew points remained above 24°C and minimal radiational cooling occurred under partly cloudy skies. Historical August climatology for central Tokyo shows typical minima of 23–25°C, so current conditions represent a notable departure driven by the ongoing warm advection. A sharp shift to northerly winds, increased cloud cover with rain, or stronger radiative cooling could push the minimum lower, though none of these developments appear imminent in the latest guidance.
