Recent developments show a low-pressure system and strengthening southwesterly monsoon flow driving frequent showers and thundershowers across northern Taiwan through the weekend, moderating daytime maxima according to Central Weather Administration guidance. This pattern favors highs near 32–34 °C in Taipei on August 22, with cloud cover and precipitation limiting radiative heating and convective mixing that could otherwise push readings toward 35 °C or above under clearer subtropical summer conditions. Historical August baselines for the region center around 32–33 °C, while model consensus highlights uncertainty in exact rainfall timing and intensity that differentiates the closely matched 32 °C, 33 °C, and 34 °C outcomes. Updated CWA forecasts and ensemble runs ahead of the date will further refine these probabilities.
