Recent forecasts from the Japan Meteorological Agency and global models indicate a highest temperature near 27–28°C in Tokyo on October 6, driven by partly cloudy skies, moderate northerly winds, and residual warmth from an early-autumn pattern that has kept much of Japan above seasonal norms. Daytime heating will depend on cloud cover and wind strength, with slight model differences in these variables separating the 26°C and 29°C outcomes. Historical early-October averages hover near 24°C, but the current positive temperature anomaly supports the market’s clustering around 27°C. Updated model runs and official JMA briefings over the next 48 hours represent the key data releases likely to influence final trader positioning.
