Recent official forecasts from Taiwan's Central Weather Administration indicate a likely high of 31°C for Taipei on August 25, with a range of 26–31°C amid partly cloudy skies and possible showers or thunderstorms. These conditions create tight market clustering around 29–31°C because convective cloud cover and rainfall can suppress peak heating by 1–2°C below clear-sky potential, while urban heat island effects and humidity may push readings slightly higher. Model consensus remains modest given the short lead time and typical August variability, with historical highs averaging near 31°C but fluctuating based on steering patterns and monsoon influences. Updated CWA guidance and ensemble runs over the next 48 hours represent key decision points for traders.
