Recent forecasts from Chinese and international models converge on overnight lows of 21–23°C for Wuhan on September 2, driven by increasing northerly flow, partial cloud cover, and light rain chances that limit radiative cooling overnight. Trader sentiment remains balanced across the 20–27°C range because ensemble spreads show sensitivity to exact cloud timing and boundary-layer mixing; clearer intervals could push minima toward 20°C while persistent overcast or showers would hold them near 23°C. Historical September climatology places typical lows near 22°C, providing context for why sub-19°C outcomes trade at single-digit implied odds. Updated model runs and local observations the evening of September 1 will refine the precise minimum before market 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=zhhh
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 which 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 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.
