Forecast models from multiple agencies currently converge on overnight lows of 21–22°C for Chongqing on September 13, driven by light winds, high humidity near 70–90%, and variable cloud cover that moderates radiative cooling after daytime highs around 27–28°C. This aligns with late-summer climatology, where September minima typically range 20–23°C amid the transition from monsoon influences. Recent surface observations on September 12 show similar conditions persisting without strong frontal passages or unusual moisture surges that might alter the range. Traders assign the highest implied probabilities to these central outcomes, reflecting model agreement on stable steering patterns and limited diurnal temperature swings, though fresh evening radiosonde data or updated runs could refine the exact minimum before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zuck
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
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 "Switch to Metric Units" button until the relevant table displays °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.
