Persistent summer warmth across Shandong province under subtropical high pressure supports the market-implied 99.4% odds for a Jinan high of 26°C or higher on August 21. Official and model consensus from sources such as the Met Office and AccuWeather project daytime maxima of 31–34°C, consistent with mid-to-late August climatology where average highs reach 31°C and extremes frequently exceed 35°C. No major cooling mechanisms, including frontal passages or widespread cloud cover, appear in current guidance. A realistic shift below 26°C would require an unforecasted cold surge or persistent heavy precipitation, both low-probability outcomes given the stable synoptic pattern and proximity to resolution.

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 21 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 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.
