Current forecasts from Taiwan's Central Weather Administration indicate overnight lows of 23–27°C in Taipei on September 20, with most models converging on a minimum near 25°C under partly cloudy to clear conditions and light easterly winds. This aligns with late-September climatology, where average nighttime lows typically range 24–26°C absent strong frontal systems or typhoon influences. Recent observations show stable humidity and no rapid cooling trends, supporting trader consensus around the 25°C outcome at 90% implied probability. Updated model runs and official briefings through the evening will refine exact resolution thresholds.
