Recent forecasts indicate a cooling trend for Tokyo on August 29 driven by increased cloud cover, scattered showers, and a shift to northeasterly winds associated with a frontal boundary and approaching low-pressure system. Official guidance from the Japan Meteorological Agency and ensemble models shows highs likely peaking near 28–29°C under mostly overcast skies, with reduced insolation and evaporative cooling from rain limiting afternoon warming compared to clearer prior days. This aligns with late-August climatology as the Pacific high weakens and northerly flow advects slightly cooler maritime air. The tight market spread between 27°C and 28°C reflects model uncertainty in exact timing of cloud breaks and precipitation intensity, which could shift the daily maximum by 1–2°C depending on the final steering pattern. Updated model runs and JMA briefings on frontal progression will refine these probabilities ahead of resolution.
