Forecast models from agencies including the China Meteorological Administration indicate a high of 32–34°C in Chengdu on September 2 under mostly clear to partly cloudy skies and light northerly winds, supporting the market’s tight clustering around 33–35°C. Clear conditions associated with a strengthening subtropical high will promote strong solar insolation and limited cloud cover, while the Sichuan basin’s topography and urban heat island effects may add 1–2°C locally during peak afternoon heating. Low precipitation probabilities (under 10%) reduce evaporative cooling, keeping temperatures near seasonal norms for early September. Minor model differences in boundary-layer mixing and exact cloud timing explain the spread between 33°C and 35°C outcomes, with latest runs favoring the middle of that range ahead of final observations.

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=zuuu
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 which 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 can not resolve until the first data point for the following date has been published on the resolution source.
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.
