**Latest ensemble forecasts and high-resolution model runs from sources like the GFS and ECMWF indicate an overnight minimum in London on September 8 most likely between 14–15°C.** A strengthening southwesterly flow ahead of an Atlantic frontal system is advecting milder maritime air while widespread cloud cover and light rain suppress radiative cooling, limiting the drop compared to clearer conditions. Dew points near 13–14°C and sustained winds around 4–5 m/s further moderate the low. Earlier runs had shown slightly cooler outcomes near 12–13°C, but recent updates have trended warmer, aligning with the near-even market split between 14°C and 15°C. The precise minimum will hinge on the timing of clearing skies after midnight and any localized variations in precipitation.

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 8 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.**Latest ensemble forecasts and high-resolution model runs from sources like the GFS and ECMWF indicate an overnight minimum in London on September 8 most likely between 14–15°C.** A strengthening southwesterly flow ahead of an Atlantic frontal system is advecting milder maritime air while widespread cloud cover and light rain suppress radiative cooling, limiting the drop compared to clearer conditions. Dew points near 13–14°C and sustained winds around 4–5 m/s further moderate the low.
