Recent forecasts from Taiwan’s Central Weather Administration indicate daytime highs near 30–33°C for Taipei on August 23, aligning with the market’s tight clustering around 31–33°C outcomes. A low-pressure system and seasonal monsoon moisture are expected to promote scattered showers or thunderstorms, which can limit daytime heating through cloud cover and evaporative cooling while maintaining high humidity. Typical late-August conditions feature urban heat-island amplification and southerly flow, yet model spreads in precipitation timing introduce uncertainty that could shift the peak by 1–2°C. Updated CWA guidance and ensemble runs over the next 48 hours will provide the clearest signals ahead of market resolution.
