**Clear skies, light northerly winds, and high pressure are driving radiative cooling overnight into September 21, positioning an 11°C minimum as the leading market outcome at 47% implied probability.** Forecasts from the Met Office and other models show temperatures falling to around 11–12°C in the early morning hours under mostly clear conditions, with some guidance dipping to 10°C. Recent observations confirm a stable anticyclonic pattern with dew points in the 8–10°C range and minimal cloud cover, favoring efficient heat loss after sunset. London’s urban heat island effect typically moderates rural lows by 1–2°C, supporting the tight clustering of probabilities around 10–12°C (collectively over 90%). Model consensus has remained steady over the past 24–48 hours with no significant shifts from incoming data, and historical September minima in London average near 11–13°C under similar setups. Key resolution will hinge on the official overnight low recorded at a designated station, with any unexpected increase in cloud or wind likely to push readings toward 12°C.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 21 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=eglc
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.**Clear skies, light northerly winds, and high pressure are driving radiative cooling overnight into September 21, positioning an 11°C minimum as the leading market outcome at 47% implied probability.**
