Recent Japan Meteorological Agency forecasts indicate a minimum temperature near 25°C for Tokyo on August 26 amid persistent above-normal summer heat driven by a strong Pacific High. This setup favors warm, humid air masses that limit nocturnal radiative cooling, while Tokyo’s urban heat island effect further elevates nighttime lows compared to rural baselines. Scattered showers and cloud cover expected that day may trap additional heat, supporting market-implied probabilities peaking at 27–28°C. Traders appear to weigh these ongoing heatwave dynamics and model consensus on limited cooling against typical August climatology of 24°C lows, with any forecast revisions from updated JMA runs or local observations likely to shift sentiment quickly ahead of resolution.
