The closely matched market-implied probabilities for a 25–27°C high in Chengdu on September 18 reflect short-term forecast uncertainty amid the onset of Hua Xi autumn rain patterns across the Sichuan Basin. Persistent cloud cover, elevated humidity near 80%, and scattered showers limit daytime solar heating while the basin's topography traps moisture and promotes night rain, keeping maxima near or slightly below the September climatological average of 25–26°C. Official guidance from the China Meteorological Administration and ensemble model runs show minor variations in precipitation timing and coverage that could shift the peak by 1–2°C, with lighter rain favoring the upper end of the range. Updated model outputs and local observations over the next 24 hours will likely narrow trader consensus before 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=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.
