**Official Central Weather Administration forecasts indicate a September 11 daytime high of 24–28°C in Taipei amid strengthening northeasterly monsoon winds that deliver cooler, moist air and widespread cloud cover.** Multiple models converge on 27–28°C maxima, with 40–80% rain probabilities and showers expected to limit solar heating and suppress peaks. Recent strengthening of these seasonal winds has already cooled surface conditions relative to early September baselines. Trader preference for 29–30°C outcomes likely reflects residual model spread on exact cloud thickness and timing of any breaks, though historical September averages and current steering patterns favor the lower end of the range. Updated CWA briefings and hourly observations will clarify whether any brief clearing allows a late spike toward 29°C.

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 11 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.**Official Central Weather Administration forecasts indicate a September 11 daytime high of 24–28°C in Taipei amid strengthening northeasterly monsoon winds that deliver cooler, moist air and widespread cloud cover.** Multiple models converge on 27–28°C maxima, with 40–80% rain probabilities and showers expected to limit solar heating and suppress peaks.
