The market-implied 100% probability for a high of 26°C or higher in Jinan on September 18 stems from official forecasts projecting daytime maxima near 30–31°C under partly cloudy skies. A high-pressure ridge has promoted subsidence and enhanced solar insolation, sustaining elevated temperatures consistent with recent regional warming patterns observed by Chinese meteorological services. Multiple model runs align on light winds and minimal precipitation, supporting peak readings well above the threshold. Only an unanticipated late surge of cooler air or station-specific measurement anomalies could realistically alter the outcome before resolution.

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 18 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.
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.
