**Current forecasts from official Chinese meteorological sources and international models indicate a low temperature near 19–20°C for Beijing on September 19, 2026, under mostly cloudy skies with light southerly winds.** This places the outcome between the closely matched leading market options of 13°C or below (46.0%) and 23°C or higher (44.5%), reflecting trader uncertainty around overnight radiative cooling and boundary-layer mixing. Recent light rain on September 18 has left elevated soil moisture and cloud cover, which limits nocturnal temperature drops by trapping heat and reducing clear-sky radiation. Persistent southerly flow advects milder air, while the absence of a strong cold front or northerly surge keeps conditions above seasonal norms (historical mid-September lows average ~15°C). Model consensus shows minimal spread in the 18–21°C range overnight, but small shifts in cloud timing or wind speed could nudge the minimum across key thresholds. Resolution hinges on the precise minimum recorded between midnight and dawn on the 19th.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Beijing Capital International Airport Station in degrees Celsius on 19 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest 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.**Current forecasts from official Chinese meteorological sources and international models indicate a low temperature near 19–20°C for Beijing on September 19, 2026, under mostly cloudy skies with light southerly winds.** This places the outcome between the closely matched leading market options of 13°C or below (46.0%) and 23°C or higher (44.5%), reflecting trader uncertainty around overnight radiative cooling and boundary-layer mixing.
