Trader consensus has converged on a 27°C high for Beijing on September 9 due to real-time official observations from meteorological stations aligning precisely with that threshold under clear skies and light southwesterly flow. This outcome sits near the long-term September 9 average high of 27.6°C, with current conditions featuring comfortable afternoon temperatures around 25–26°C and minimal diurnal variation that prevented further rise. Model consensus from regional forecasts showed limited upside potential once the midday peak passed, locking in the result. Only an unexpected post-hoc data revision from primary monitoring agencies could alter resolution, though such adjustments remain rare for surface temperature records.

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=zbaa
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.
