Forecasts from the China Meteorological Administration and global models indicate a daily maximum near 27–28°C for Beijing on September 19 under partly cloudy conditions and light southerly flow, consistent with late-summer climatology where average highs reach about 25.6°C. Recent model runs show limited afternoon warming potential amid stable high pressure and minimal moisture, keeping the distribution centered on 28–29°C while capping upside risk above 30°C. Trader consensus reflected in the market prices aligns with these official guidance updates, emphasizing the narrow range of possible outcomes given the short lead time and absence of strong synoptic drivers.

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.
