**Forecast consensus from Central Weather Administration and multiple models points to a minimum temperature in Taipei on September 20 near 23–24°C, supporting the closely matched market-implied odds for 24°C and 25°C.** A northeasterly wind flow continues to moderate conditions across northern Taiwan, limiting nocturnal radiative cooling while maintaining humidity levels that favor overnight lows in the low-to-mid 20s. Partly cloudy skies and a modest 20% chance of light showers or drizzle could further reduce temperature drops by trapping heat, with model spreads reflecting minor variations in wind speed and cloud timing. Historical September baselines show typical minima around 23–24°C, and absent any strong frontal systems or typhoon influences, the tight clustering of probabilities around 24–25°C captures genuine uncertainty in the precise overnight minimum ahead of final model runs.
