Current meteorological forecasts from regional models indicate a minimum temperature of 20°C in Beijing on September 6, driven by stable high-pressure conditions and southerly flow maintaining mild overnight lows near historical September averages of 18°C. Official observations and ensemble guidance show limited diurnal cooling under partly cloudy skies with dew points supporting this threshold, aligning with the market's overwhelming 99% implied probability for 20°C. This consensus reflects real-time data assimilation rather than long-term trends. Uncertainties remain from potential model revisions in steering patterns or localized urban heat effects that could nudge readings slightly lower, though significant deviations below 19°C appear unlikely without abrupt frontal passage.

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=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.
