Recent weather observations and forecasts for Chengdu indicate persistent cloud cover, moderate northeasterly winds, and scattered rainfall on September 9, 2026, which are moderating overnight radiative cooling and keeping minimum temperatures clustered near 18–21°C. The early onset of the Hua Xi autumn rain pattern has advected cooler, moister air into the Sichuan Basin, suppressing diurnal temperature ranges compared with climatological norms for early September. Model consensus from sources such as ECMWF and GFS shows limited spread in the overnight low, with the primary uncertainty arising from the exact timing and intensity of showers that could enhance or limit evaporative cooling. High humidity near 80–90% and light winds further stabilize the boundary layer, reducing the likelihood of either sharp drops below 18°C or sustained readings above 21°C. Traders are therefore weighting outcomes around the observed and projected minimum most heavily, as new hourly data or updated model runs could shift the recorded low by 1–2°C before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
