Latest forecast models indicate a high near 34°C in Wuhan on September 8 under partly cloudy skies, light northeast winds, and negligible precipitation risk, consistent with the market's heavy weighting toward 34°C and 35°C outcomes. Regional high-pressure patterns and seasonal warmth support this range, exceeding the historical September average of roughly 28°C while falling short of peak summer extremes. Model consensus shows limited spread, with some sources projecting up to 35–36°C under stronger insolation and others closer to 33°C if cloud cover increases. Official station readings, which resolve the market, will incorporate local urban effects, and any late-day revisions from updated guidance could shift probabilities 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=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.
