Current forecast models from Chinese meteorological agencies point to a Jinan minimum near 20°C on September 18 under persistent high-pressure ridging and “autumn tiger” warming from recent large-scale circulation shifts. Large diurnal ranges of 10–12°C, light variable winds, and limited overnight cloud cover support this range, while urban heat-island effects and exact station siting introduce 1–2°C uncertainty among 16–21°C outcomes. Official China Meteorological Administration observations will determine resolution, with any late-model cooling or clearer skies able to tip the lowest reading toward 17°C or below.

This market will resolve based on the lowest 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 lowest 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 lowest 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.Current forecast models from Chinese meteorological agencies point to a Jinan minimum near 20°C on September 18 under persistent high-pressure ridging and “autumn tiger” warming from recent large-scale circulation shifts.
