Traders assign the highest implied probabilities to 25°C and 26°C because official Central Weather Administration guidance and ensemble model runs project overnight lows in Taipei near that range for August 26, consistent with seasonal August averages of 24–27°C. Persistent cloud cover and scattered showers tied to a nearby tropical depression are expected to limit radiational cooling while maintaining high humidity, keeping the minimum from dropping below 24°C or rising above 27°C. Minor forecast divergences in shower timing and wind direction create the tight spread between the two leading outcomes, with resolution depending on the precise 24-hour minimum recorded at the official station.
