Recent forecast guidance from regional models points to overnight lows in Chongqing on September 9 clustering near 27–28°C, reflecting the tight clustering of market-implied odds. Partly cloudy skies and light southeasterly flow are expected to limit radiative cooling after a hot day with highs near 34–36°C, while scattered showers or elevated humidity may enhance downward mixing and nudge minima slightly lower. Urban heat-island effects and basin topography further compress the range of possible outcomes, keeping 26°C and 30°C probabilities competitive. Updated runs from the China Meteorological Administration and verification of evening observations will refine the final 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.
