The northeast monsoon currently influencing northern Taiwan is the dominant factor capping Taipei's maximum temperature on September 11, with official Central Weather Administration forecasts indicating a high of 24–29 °C amid widespread cloud cover, elevated humidity, and scattered showers. Persistent northeasterly flow advects cooler, moist air that reduces solar insolation and promotes evaporative cooling, keeping the daily peak near or below 29 °C according to consensus model guidance. Trader consensus clustering around 28–30 °C reflects uncertainty in the precise timing of any brief clearing or localized heating, while probabilities for 31 °C or higher remain low given the expected rain-cooled boundary layer. Updated model runs and CWA briefings over the next 48 hours will refine the exact threshold.

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.The northeast monsoon currently influencing northern Taiwan is the dominant factor capping Taipei's maximum temperature on September 11, with official Central Weather Administration forecasts indicating a high of 24–29 °C amid widespread cloud cover, elevated humidity, and scattered showers.
