Recent forecasts from multiple models indicate a minimum temperature in Wuhan on September 9 likely between 19–21°C, driven by northeasterly winds advecting cooler, drier air from higher latitudes and increased cloud cover reducing overnight radiative cooling. This follows several days of warmer minima near 23–25°C under clearer, more humid conditions. Scientific factors differentiating the closely matched 20–23°C outcomes include variations in boundary-layer mixing from wind speeds of 10–15 km/h, dew point depressions around 5–8°C, and subtle differences in model handling of urban heat island effects versus regional advection. Traders appear to weight ensemble consensus from agencies like the China Meteorological Administration alongside historical September climatology (average low ~22°C), with resolution hinging on official overnight observations.

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 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.
