Forecast models from agencies including the China Meteorological Administration and global ensembles like ECMWF show Beijing's September 13 maximum temperature centered near 30–31°C, with the tight clustering of market-implied odds reflecting remaining uncertainty in 48-hour guidance. Mid-September climatology places average highs around 27–29°C, but persistent high pressure and reduced cloud cover have supported daytime warming above seasonal norms. Key variables include afternoon boundary-layer mixing, urban heat retention, and any late-day sea-breeze influence from the Bohai Sea that could shave 1–2°C. Updated model runs and morning observations will narrow the range before resolution, with traders weighting ensemble spread and historical forecast error for similar synoptic patterns.

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.
