Current forecasts from multiple meteorological sources indicate a daily low near 24–25°C for Taipei on September 27, aligning with the market's leading 25°C outcome at 44% implied probability. Late-September seasonal transition brings strengthening northeast monsoon influences, drier air masses, and clearer skies that enhance nighttime radiative cooling after daytime highs reach 30–33°C. Light winds and minimal cloud cover further promote heat loss from the surface, widening the diurnal range compared to peak summer conditions. With resolution imminent, any last-minute shifts in humidity or wind patterns could nudge the minimum slightly higher or lower, though model consensus currently favors the mid-20s range over extremes.
