Recent official forecasts from the UK Met Office and other models indicate a mild overnight period for London on September 22, with minimum temperatures most likely reaching 14–15°C under partly cloudy skies and light southerly flow. This positioning reflects limited radiative cooling overnight amid above-average September warmth, with daytime highs near 23–25°C and no significant cold advection expected. Ensemble guidance shows tight clustering in the 14–16°C range, consistent with the market’s heavy weighting on those outcomes, while lower probabilities for 13°C or below reflect the low chance of clearer skies or a sharper northerly shift. Updated model runs and Met Office briefings over the next 12–24 hours will provide the final data for resolution.

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 22 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.Recent official forecasts from the UK Met Office and other models indicate a mild overnight period for London on September 22, with minimum temperatures most likely reaching 14–15°C under partly cloudy skies and light southerly flow.
