Recent forecasts from multiple meteorological sources indicate Beijing's minimum temperature on September 23 will likely fall in the 17–19°C range under mostly cloudy skies with light southerly winds shifting northeast. This reflects a stable, mild late-summer pattern with no strong cold-air advection or clear-sky radiative cooling expected, keeping overnight lows well above the 14.2°C climatological average. Model consensus shows limited day-to-day variability, though minor differences in cloud cover or wind speed could shift the exact minimum by 1–2°C. The even market split between extremes highlights uncertainty around tail risks—such as an unforecasted frontal passage or enhanced radiational cooling—while the bulk of probability clusters on mid-range outcomes consistent with current observations and seasonal norms. Updated model runs from official agencies will refine these details ahead of the date.

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.
