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 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 forecasts from Taiwan’s Central Weather Administration (CWA) indicate a daytime high of 34–35°C in Taipei on August 18 under mostly clear to partly cloudy skies with afternoon thundershowers. This pattern aligns with typical late-summer conditions driven by southwesterly monsoon flow, which brings heat and humidity while scattered convection often prevents temperatures from exceeding model guidance. Historical August averages for Taipei hover near 32–33°C, but recent days with similar clear morning conditions have reached 35–36°C before showers develop. Market-implied odds cluster tightly around 35°C (43%) and 34–36°C combined (over 90%), reflecting trader assessment of CWA guidance and ensemble model consensus. Afternoon convection and urban heat-island moderation introduce minor downside risk to the peak reading, while any delay in shower initiation could allow a brief spike toward 36°C. No significant tropical systems or unusual synoptic shifts are currently indicated that would alter this range before resolution.
