Recent forecast models from sources including the China Meteorological Administration and international ensembles converge on a daily high of 22–25°C for Chongqing on September 15, driven by northerly flow, extensive cloud cover, and light-to-moderate rain that limits daytime heating. High humidity near 85–95% and minimal solar insolation further suppress temperature rise compared with clearer September baselines. Minor model differences in timing and intensity of precipitation create the narrow spread among the leading market outcomes at 22–24°C, with traders weighting the latest runs showing peaks near 23–24°C. Updated guidance ahead of local midnight will refine the precise maximum recorded at official stations.

The resolution source for this market will be information from NOAA, specifically the highest 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.
