Recent Central Weather Administration forecasts project daytime highs of 34–36°C in Taipei on August 15 amid typical late-summer subtropical conditions, with ample solar insolation under a ridge of high pressure and weak steering winds. Afternoon thundershowers, common in the region due to diurnal heating and moisture from the East Asian monsoon, introduce the main uncertainty: early or widespread convection could suppress peaks toward 32–33°C by enhancing cloud cover and evaporative cooling, while delayed or isolated storms would favor 35–36°C readings. Historical August maxima frequently reach 34–36°C, and current model consensus shows limited spread, aligning with the market’s closely matched probabilities across the 32–36°C range. Updated CWA guidance and short-range model runs over the next 48 hours will likely refine the outcome.
