Recent forecasts from Taiwan's Central Weather Administration and international models indicate overnight lows in Taipei settling near 23–24°C on September 21 under mostly clear skies and light northeasterly winds of 3–5 m/s. These conditions promote modest radiative cooling after daytime highs near 30°C, consistent with subtropical September climatology where minimum temperatures typically range 23–25°C absent strong frontal systems or typhoon influences. Trader consensus around these thresholds reflects model agreement on stable high pressure and low precipitation risk, though minor variations in station microclimate or exact timing of the daily minimum could shift the recorded value within a narrow band. Updated observations from official monitoring will determine final resolution.
