Recent forecasts from multiple meteorological sources indicate a high of 27–28°C in Chengdu on September 21 under mostly cloudy to overcast skies with light winds and high humidity, reflecting the typical late-September transition to cooler autumn conditions after the East Asian monsoon retreat. Trader emphasis on 28°C and 29°C stems from model consensus on modest daytime heating, where brief periods of reduced cloud cover could allow temperatures to edge higher, while persistent overcast limits peaks near 27°C. These close probabilities capture genuine uncertainty in short-term boundary-layer mixing and insolation under variable cloud regimes, with final resolution depending on official observations from the China Meteorological Administration.

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 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.
