Recent Central Weather Administration forecasts indicate overnight lows in Taipei on August 31 will likely settle near 26°C under increasing cloud cover and showers tied to a developing low-pressure system and southwesterly moisture flow. This setup promotes greater radiative cooling suppression than clear summer nights, keeping minimum temperatures clustered around 25–27°C while limiting daytime peaks. Ensemble guidance shows modest divergence on exact cloud persistence and rainfall timing, which directly influences the narrow spread between the market’s top outcomes at 26°C and 27°C. Historical August baselines near 25°C provide context, yet the current pattern favors slightly milder minima than average. Updated model runs and CWA briefings over the next 48 hours will refine these thresholds ahead of market resolution.
