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 5 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.
Persistent northeasterly flow and outer bands from a nearby tropical system are expected to sustain cloud cover and scattered showers across northern Taiwan on September 5, moderating daytime heating and keeping maximum temperatures near the seasonal norm of 30–32 °C. Official Central Weather Administration guidance lists a 26–31 °C range for Taipei, while ensemble guidance and local models show modest spread around 29–32 °C depending on the timing and intensity of precipitation. High humidity and reduced insolation under overcast skies limit the potential for stronger surface warming, whereas any temporary breaks in cloud cover could allow brief excursions toward 32 °C. Market-implied probabilities clustered at 30–32 °C reflect this narrow uncertainty band ahead of the next model runs and afternoon observations.
