Official forecasts from Taiwan's Central Weather Administration project a daytime maximum of 34°C in Taipei on August 29 under partly cloudy conditions with afternoon thunderstorms, consistent with late-summer climatology featuring high humidity, light winds, and typical convective suppression of peaks. Trader emphasis on 35°C as the leading outcome reflects model spread in timing of showers, recent days' observed highs near 35–36°C, and the chance that brief clearing periods allow stronger insolation before convection develops. Afternoon precipitation probability around 65% introduces downside risk to 33°C or below if storms arrive early, while weaker steering flow could permit brief excursions toward 36°C. Updated model runs and CWA briefings on August 28–29 will refine these thresholds ahead of market resolution.
