Recent rainfall and persistent cloud cover from subtropical high influences combined with weak cold air advection are the main drivers keeping Beijing's August 28 daytime heating limited, with official China Meteorological Administration and ensemble forecasts converging on a high near 22–24°C amid scattered showers. This contrasts with late-August climatological averages near 29–30°C and reflects the cooling effect of widespread precipitation earlier in the week. Model consensus supports suppressed maxima, though minor variations in timing or intensity of any clearing could shift the peak by 1–2°C and differentiate the closely matched market outcomes. Updated guidance from monitoring agencies will provide the next key inputs ahead of 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=zbaa
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
