Recent official forecasts from Taiwan's Central Weather Administration indicate a daytime high near 34°C for Taipei on August 28, with ranges typically spanning 27–34°C amid mostly cloudy conditions and a chance of afternoon showers or thunderstorms. This uncertainty stems from variable steering patterns, high humidity fueling convective activity, and differences among numerical weather prediction models regarding the timing and intensity of peak heating versus cooling from precipitation. Historical late-August climatology shows average highs around 32–33°C, with occasional spikes above 34°C under clearer skies, while any earlier or stronger storms could cap the maximum lower. The balanced market-implied odds across temperature thresholds capture traders' weighting of these atmospheric variables and upcoming model updates ahead of the date.
