Recent forecasts from the Central Weather Administration and global models indicate a stable easterly flow over northern Taiwan, with mostly cloudy to overcast skies, light drizzle potential, and moderate humidity suppressing peak heating on September 17. This setup favors daytime maxima near 28–29°C, consistent with recent days under similar northeast winds. Trader emphasis on 31–32°C outcomes likely reflects uncertainty in afternoon cloud breaks or model spread on boundary-layer mixing, which could allow brief warming above the baseline. Historical September averages for Taipei hover around 30–32°C, but persistent marine influence and 60–80% cloud cover this period tilt probabilities toward the lower end of the range. Updated CWA guidance and ensemble runs ahead of resolution will clarify any intensification in solar insolation or wind shifts.
