Recent Japan Meteorological Agency forecasts for Tokyo indicate a maximum of 33–34°C on August 26, consistent with trader emphasis on those outcomes amid the broader summer heat pattern. Persistent Pacific high pressure has driven above-normal temperatures across Honshu, with historical late-August averages near 31°C serving as the baseline. Key variables include potential scattered showers and increased cloud cover, which could limit afternoon heating and favor 33–34°C, versus clearer conditions allowing a push toward 35°C. Ensemble model spreads reflect typical short-range uncertainty in boundary-layer moisture and timing of any precipitation, keeping the 34–35°C range dominant while lower probabilities attach to extremes outside recent observational trends.
