Trader sentiment for Chengdu's August 28 minimum temperature shows near-even odds between sub-20°C and 29°C+ outcomes because short-range ensemble forecasts from ECMWF and GFS display substantial spread in boundary-layer moisture and nocturnal cloud cover. The Sichuan basin's topography often traps humid air masses during late-summer monsoon flow, which can suppress radiative cooling and keep overnight lows near 24–26°C under partly cloudy conditions or allow sharper drops if clear skies and drier northerly advection develop. Recent model runs indicate modest differences in precipitation timing that could shift minimum readings by several degrees. Next high-resolution updates from the China Meteorological Administration and additional satellite-derived moisture profiles will likely narrow the current uncertainty.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
