Recent forecasts from Taiwan’s Central Weather Administration indicate daytime highs in Taipei reaching 34–35°C on August 21 amid typical late-summer conditions of high humidity and scattered thunderstorms. These values align with climatological averages near 33–34°C but could shift with afternoon convection or clearer skies that allow greater insolation. Model consensus points to a steering pattern favoring localized heating rather than widespread cooling from rain, though any intensification of showers would likely suppress peak readings. Traders monitor real-time updates to apparent temperature indices and official station data, which resolve markets based on verified daily maxima. With resolution imminent, incremental forecast revisions from the next model runs represent the main catalyst for sentiment shifts.
