Current forecasts from Taiwan's Central Weather Administration and ensemble models indicate a northeasterly monsoon flow will limit daytime heating over Taipei on September 19, supporting a peak near 31–32°C with partly cloudy skies and minimal precipitation. This setup aligns with September climatology of roughly 31°C average highs, though urban heat island effects and variable cloud cover introduce uncertainty between 32°C and 33°C outcomes. Model runs differ modestly on peak insolation timing and boundary-layer mixing, while a distant tropical depression poses no direct influence. Traders' tight split between these two leading contracts reflects that narrow scientific margin, with fresher observational data expected to refine the exact maximum before resolution.

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 19 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 Taiwan's Central Weather Administration and ensemble models indicate a northeasterly monsoon flow will limit daytime heating over Taipei on September 19, supporting a peak near 31–32°C with partly cloudy skies and minimal precipitation.
