Recent forecasts from multiple models project a high of 30–32°C for Jinan on September 18 under mostly cloudy to partly sunny conditions with light southerly or variable winds and minimal precipitation risk. This aligns with late-summer warmth persisting across the North China Plain, where daytime heating remains elevated relative to the September climatological average of roughly 27°C. Consensus across sources such as AccuWeather and regional outlooks shows no significant frontal passage or increased cloud cover sufficient to suppress maxima below 26°C. With resolution hinging on official station observations, traders have placed strong weight on the 26°C-or-higher outcome at 88% implied probability, reflecting the narrow uncertainty band around the expected peak.

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 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.Recent forecasts from multiple models project a high of 30–32°C for Jinan on September 18 under mostly cloudy to partly sunny conditions with light southerly or variable winds and minimal precipitation risk.
