Forecast models from sources including the China Meteorological Administration and international ensembles indicate a transitional pattern for Jinan on September 7, with daytime highs near 31–33 °C giving way to an overnight minimum shaped by increasing northeasterly flow and partial cloud cover that could limit radiational cooling. This setup creates tight uncertainty around the precise low, as small shifts in timing of the approaching cooler air mass or boundary-layer moisture can alter the minimum by 1–3 °C. Historical September climatology shows typical overnight lows near 18 °C, yet current guidance clusters 20–22 °C; traders therefore price nearby bins such as 17 °C and 18 °C near even money while assigning substantial implied probability to 12 °C or below, reflecting both model spread and the possibility of faster advection. Official station data released after the period will resolve the market.

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 7 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.
