This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section. This market will resolve to the temperature range that contains the highest temperature recorded at the Taipei Songshan Airport Station in degrees Celsius on 5 Sep '26. The resolution source for this market will be information from Wunderground, specifically the highest 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.
Persistent cloud cover, widespread showers, and northwest winds associated with the East Asian monsoon are capping daytime heating in Taipei ahead of September 5, keeping most official guidance centered on highs of 28–30 °C. Model consensus shows only modest afternoon breaks in precipitation that could briefly allow temperatures to reach 31–32 °C if insolation increases, while stronger or more persistent rain would hold readings near 29 °C. High dew points near 25 °C and elevated humidity further compress the diurnal range, consistent with September climatology of roughly 30 °C average highs. Traders appear to weigh these variables evenly, producing closely matched probabilities for 30–32 °C outcomes. Updated short-range model runs and Central Weather Administration forecasts on September 5 will provide the key resolution data.
