**Official station observations from Jinan on September 5 confirmed a daily minimum of 16°C under clear skies and light winds that promoted strong nocturnal radiative cooling.** This aligns with early-September climatology for the North China Plain, where daytime highs near 30–32°C often yield nighttime drops of 10–14°C in the absence of cloud cover or strong advection. Trader consensus at 99.5% for the 16°C outcome reflects high confidence in China Meteorological Administration data, with minimal model divergence or station discrepancies noted in post-event verification. A realistic challenge would require an official data revision or alternative station reading falling outside the 16°C bin, though current evidence indicates low probability of such an adjustment.

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 5 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.
