Current forecasts from the China Meteorological Administration and international models indicate a minimum temperature near 19°C for Beijing on August 30 under clearing skies and light northwest winds following recent showers. This aligns with the historical late-August average low of about 19.6°C and typical radiative cooling overnight in stable high-pressure conditions. Key variables differentiating outcomes include the precise timing of cloud dissipation, which modulates nocturnal heat loss, versus any lingering humidity or urban heat island effects that could elevate readings above 20°C. Model consensus remains tight around 18–20°C, though small shifts in steering flow or local observations could narrow probabilities among the clustered 17–23°C bins while keeping sub-13°C scenarios improbable.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
