**Current forecasts from multiple models converge on a daily maximum of 30–32°C for Taipei on September 21, 2026, aligning with the market’s leading probabilities of 32°C (48.5%), 33°C (23.5%), and 31°C (20.0%).** Northeast monsoon flow, combined with partly cloudy to clear skies and light winds, supports moderate daytime heating while limiting extreme warmth. Relative humidity around 60% and minimal precipitation risk (under 10%) favor efficient surface warming without significant cloud cover or rain cooling. September’s climatological average high near 31°C provides context, with the current setup reflecting a typical seasonal transition rather than anomalous conditions. Official resolution will rely on Central Weather Administration station observations, with any late-model shifts in steering flow or cloud development able to nudge the peak by 1–2°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 21 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.**Current forecasts from multiple models converge on a daily maximum of 30–32°C for Taipei on September 21, 2026, aligning with the market’s leading probabilities of 32°C (48.5%), 33°C (23.5%), and 31°C (20.0%).** Northeast monsoon flow, combined with partly cloudy to clear skies and light winds, supports moderate daytime heating while limiting extreme warmth.
