Recent Met Office guidance points to a minimum of 14°C in London on September 22 under high pressure, clear skies, and light southwesterly winds that favor modest overnight radiative cooling. This aligns with the market’s leading outcomes at 14–15°C, as traders weigh the warm late-summer air mass against typical September lows near 11°C. Model consensus remains tight, though small differences in cloud cover or urban heat-island effects could shift the exact reading by 1°C. Updated forecasts and any last-minute changes in boundary-layer conditions will be the key near-term catalysts.

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 Met Office guidance points to a minimum of 14°C in London on September 22 under high pressure, clear skies, and light southwesterly winds that favor modest overnight radiative cooling.
