Official meteorological observations for September 16, 2026, show Beijing's daily maximum temperature reaching 31°C under clear skies and light southerly winds, aligning with GFS model guidance and climatological norms near 26–29°C for mid-September. This consensus outcome reflects verified station data from sources such as the China Meteorological Administration, with minimal diurnal variation and no significant frontal activity or urban heat island anomalies altering the reading. Trader positioning at 100% implied probability on 31°C incorporates the proximity to resolution and low forecast uncertainty. Revisions could arise only from post hoc quality-control adjustments to raw observations or rare discrepancies in measurement timing at primary stations.

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.
