Recent forecast guidance from Chinese meteorological sources and international models indicates a sunny to mostly cloudy day in Chengdu with highs likely peaking near 32–33°C under subtropical high pressure influence, though some runs show afternoon maxima closer to 29–30°C amid variable humidity and light northeast winds. This positions 28–30°C as the most probable resolution range for official station readings, driving the concentrated market-implied odds there while higher outcomes reflect residual uncertainty in model spread and exact peak timing. Historical September baselines near 27°C underscore the current warm anomaly, with traders weighting real-time observational updates heavily ahead of final daily verification.

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.
