**Latest forecast models for Taipei on September 2 point to a daytime high in the low-to-mid 30s Celsius, shaped by persistent subtropical moisture, easterly flow, and high humidity that limits radiative heating.** Multiple short-range guidance runs show highs clustered near 29–32 °C under partly cloudy to overcast skies with scattered showers or thunderstorms, consistent with the climatological pattern of September’s monsoon trough and frequent convective activity. Urban heat-island effects in the Taipei basin can add 1–2 °C locally during peak insolation, while any reduction in cloud cover or rainfall would allow temperatures to edge toward 33–35 °C. Current model consensus favors the lower end of that range because of elevated precipitable water and easterly winds that promote marine-layer moderation. Traders appear to be weighting the upper tail of ensemble spreads and recent warm anomalies, producing the observed market concentration on 33–35 °C outcomes. The next official Central Weather Administration (CWA) guidance updates and real-time observational trends through the evening of September 1 will be the key near-term catalysts.
