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 Jinan Yaoqiang International Airport Station in degrees Celsius on 1 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 Jinan Yaoqiang International Airport Station, available here: https://www.wunderground.com/history/daily/cn/jinan/ZSJN. 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.
Traders assign a 99.5% implied probability to a daily maximum of 26°C or higher in Jinan on September 1 because long-term climatology places average early-September highs near 27–29°C, with historical observations on that date frequently reaching 28–35°C under typical subtropical high-pressure influence. Current model guidance and short-term forecasts reinforce this pattern, projecting mostly sunny skies, light northeasterly flow, and afternoon peaks of 28–30°C with minimal cloud interference or precipitation. The market therefore reflects robust scientific consensus on seasonal persistence of summer warmth rather than any anomalous event. Only an unexpected late-season cold surge or prolonged overcast conditions—rare for the region at this time—could realistically push the maximum below the threshold.
