Latest ensemble forecasts from multiple models highlight persistent cloud cover and scattered showers over Chengdu on September 23 as the main factor capping highs near 24–27°C, aligning with the closely matched market-implied odds across those outcomes. Reduced solar insolation from overcast skies and evaporative cooling from precipitation limit daytime warming in the Sichuan basin during this transitional autumn period. Model differences in cloud thickness, wind patterns, and any late-day clearing introduce the 1–2°C spread separating the leading probabilities, while historical September maxima average around 25°C. Updated runs from major agencies and official monitoring briefings in the next 24–48 hours represent the key data points that could shift trader consensus.

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.
