Recent Central Weather Administration forecasts and ensemble model runs indicate a highest temperature in Taipei on September 18 most likely between 28–32 °C, driven by persistent northeast monsoon flow and moderate cloud cover that limit daytime heating. Current conditions feature ENE winds of 5–7 m/s, relative humidity near 65–80 %, and only isolated drizzle chances, which cap surface temperatures below peak summer values. Historical September baselines average around 31 °C, and the absence of strong subsidence or clear-sky amplification in the latest model guidance supports trader emphasis on 31 °C as the modal outcome. Updated model runs and any shifts in steering patterns over the next 48 hours remain the key variables that could adjust these market-implied probabilities.

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 18 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.Recent Central Weather Administration forecasts and ensemble model runs indicate a highest temperature in Taipei on September 18 most likely between 28–32 °C, driven by persistent northeast monsoon flow and moderate cloud cover that limit daytime heating.
