Recent northerly winds and widespread light rain across Beijing have driven a sharp cooldown from prior highs near 28–29°C, with official forecasts converging on a maximum of 21–24°C under persistent cloud cover that limits solar heating. Model runs highlight subtle differences in rainfall timing and intensity as the key variables separating 23°C versus 24°C outcomes, while dew points around 14–16°C and light winds further constrain afternoon peaks. Traders' tight clustering around these values reflects the narrow uncertainty band typical of late-summer frontal passages, with resolution hinging on the precise peak recorded before evening clearing.

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.
