**Trader consensus on a 23°C high for Chengdu on September 19, 2026, reflects current forecast model outputs showing a maximum near that threshold under persistent cloud cover and light northeasterly winds.** Official guidance and ensemble runs indicate daytime peaks limited to around 23°C, with hourly readings expected to top out in the early afternoon before cooling under overcast skies and high humidity near 80-90%. This positioning aligns with autumnal cooling patterns in the Sichuan Basin, where reduced solar heating and regional moisture suppress temperatures below late-summer norms. A realistic challenge would require unexpected afternoon clearing or model error allowing a brief spike to 24°C or higher, though current observational trends and short-range guidance make such a shift unlikely 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.
