Official observations from the Japan Meteorological Agency confirm a daily maximum of 22°C in Tokyo on October 5, 2026, with hourly readings peaking at that level around midday under mostly cloudy skies, light northwesterly winds, and minimal precipitation. This aligns precisely with trader consensus at 100% implied probability, reflecting the reliability of surface station data and model agreement on autumn cooling trends following September warmth. Historical October averages near 23–25°C provide context for the subdued reading. Revisions remain possible only if post-analysis adjustments alter the official high or if resolution criteria shift to a specific station or time window, though current verified measurements make such changes improbable.
