**Persistent warm atmospheric conditions and model consensus for highs near 28–29°C underpin the 86% market-implied probability of 26°C or higher as Jinan’s maximum on September 21.** Recent high-pressure ridge adjustments have sustained above-average temperatures across Shandong, with September 20 observations around 28–30°C and limited cold-air intrusion expected overnight. Global and regional forecast models, including those aligned with China Meteorological Administration guidance, project mostly cloudy skies transitioning to clearer conditions, light northerly winds, and minimal precipitation that favor daytime warming without significant cooling. Historical September averages near 26°C provide context, yet current steering patterns and weak frontal activity keep cooler outcomes below 25°C at low probabilities. Official station readings the following day will resolve the market amid typical late-summer variability.

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 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.**Persistent warm atmospheric conditions and model consensus for highs near 28–29°C underpin the 86% market-implied probability of 26°C or higher as Jinan’s maximum on September 21.** Recent high-pressure ridge adjustments have sustained above-average temperatures across Shandong, with September 20 observations around 28–30°C and limited cold-air intrusion expected overnight.
