Forecasts from multiple models indicate the lowest temperature in Taipei on September 14 will most likely fall between 24–25°C, consistent with the market-implied probabilities peaking at 25°C (32.5%) and 24°C (21.5%). Persistent northeast monsoon flow, high humidity near 80–95%, and scattered showers or cloud cover limit overnight radiative cooling, keeping minima above the September climatological low of ~24°C. Key variables include the exact timing and intensity of precipitation, which can suppress daytime highs while maintaining warmer nights, versus clearer intervals that allow greater cooling. Model consensus shows stable high pressure with light to moderate winds, reducing the chance of extremes below 21°C or above 26°C. Updated official guidance from agencies like Taiwan’s Central Weather Administration will refine these ranges ahead of resolution.
