Latest Japan Meteorological Agency forecasts for August 22 indicate a high near 32–33°C under cloudy skies with scattered showers possible later, aligning with ensemble model guidance and supporting the tight market clustering around 31–32°C. Differentiation between these thresholds hinges on afternoon cloud thickness and shower timing, which can suppress peak solar insolation by 1–2°C, alongside Tokyo’s urban heat island amplification and prevailing southeasterly flow. Historical August baselines average 31°C, but recent above-normal seasonal outlooks and minimal typhoon influence keep trader focus on short-term model runs expected from JMA and global centers before resolution.
