Recent forecasts from multiple models converge on a daytime high of 23–25°C in Chongqing for September 17, driven by persistent light rain, extensive low cloud cover, and light variable winds that limit solar heating and promote evaporative cooling. High humidity near 90% and overnight lows around 20–21°C further constrain daytime warming, consistent with the seasonal transition toward cooler autumn conditions in the Sichuan Basin. Trader emphasis on 22–24°C outcomes reflects this consensus while acknowledging minor model spread in cloud breaks or rainfall timing that could nudge the peak slightly higher or keep it suppressed. Official updates from agencies like the China Meteorological Administration will refine the exact maximum ahead of market resolution.

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.
