Recent forecasts from Taiwan's Central Weather Administration indicate mostly cloudy to overcast conditions for Taipei on August 28, with daytime highs near 34°C and overnight lows around 26–27°C, supporting trader focus on those thresholds. Cloud cover and scattered showers tied to typhoon outer bands or monsoon influences limit nighttime radiative cooling, narrowing the diurnal range and keeping minimums from dropping toward 24–25°C. Ensemble model spreads and recent adjustments in steering patterns create the tight 27–28°C contest, as clearer breaks could allow slightly more cooling while persistent moisture favors warmer readings. Updated CWA guidance and high-resolution model runs over the next 48 hours will likely refine the exact low ahead of market resolution.
