Northeast monsoon winds currently dominate northern Taiwan, introducing cooler maritime air and persistent cloud cover that limit daytime heating while promoting radiational cooling overnight, creating the tight split in market-implied odds between sub-20°C and 30°C+ outcomes for Taipei’s September 11 low. Official Central Weather Administration guidance and ensemble models show expected minima near 23–25°C amid light rain and northeasterly flow at 10–15 km/h, consistent with climatological September baselines yet sensitive to small shifts in monsoon strength or timing of showers. Any weakening of the flow or clearer skies could push readings higher, while stronger winds or heavier precipitation would favor the cooler tail; updated model runs and overnight observations will provide the next key signals before resolution.

This market will resolve based on the lowest 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 lowest 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 lowest 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.
