Persistent cloud cover, high humidity, and widespread thunderstorms forecast for September 4 are limiting radiative cooling overnight in Taipei, keeping minimum temperatures from falling below the mid-20s °C. Multiple forecast models, including those referenced by the Central Weather Administration and international services, project lows clustered between 24–26 °C under these conditions, with 26 °C emerging as the modal outcome in recent runs. Persistent moisture from upstream weather systems has maintained elevated dew points near 25 °C, reducing the diurnal temperature range compared with clearer September climatology. Traders have priced this consensus into the market, assigning the highest implied probability to 26 °C while assigning lower odds to cooler extremes that would require unexpected clearing or stronger northerly flow. Updated model guidance over the next 24–48 hours will determine whether probabilities shift toward 24–25 °C or remain anchored near 26 °C.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Taipei Songshan Airport Station in degrees Celsius on 4 Sep '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Taipei Songshan Airport Station, available here: https://www.wunderground.com/history/daily/tw/taipei/RCSS.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
