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 20 Aug '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. 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 can not resolve until the first data point for the following date has been published on the resolution source. 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.
Official Taiwanese Central Weather Administration guidance points to a daytime high of 33–34°C for Taipei on August 20 amid mostly cloudy skies and scattered showers or thunderstorms, while global models show modest spread around that range. Frequent afternoon convection, typical of late-summer monsoon flow, can limit peak insolation and thereby cap temperatures near the lower end of the distribution; conversely, any breaks in cloud cover or delayed rain onset would favor readings at or above 34°C. High boundary-layer humidity and the urban heat-island effect of the Taipei basin add several tenths of a degree relative to surrounding rural stations. With forecast guidance still evolving through the final model runs before local midnight, traders are balancing the probability-weighted outcomes of these meteorological variables.
