Official forecasts from the UK Met Office and supporting models indicate a minimum temperature of 18°C for London on September 14, driven by mild southwesterly airflow, persistent cloud cover that limits overnight radiative cooling, and elevated humidity levels near 90% that moderate temperature drops. Recent model runs show consistency around 17–18°C lows, with limited overnight clearing expected to prevent sharper declines below 16°C. Trader consensus aligns with these projections, as historical September minima in the city average near 12–14°C but current synoptic patterns favor milder conditions without significant cold advection. Updated guidance later today could refine exact thresholds if any model divergence emerges.

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 14 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.Official forecasts from the UK Met Office and supporting models indicate a minimum temperature of 18°C for London on September 14, driven by mild southwesterly airflow, persistent cloud cover that limits overnight radiative cooling, and elevated humidity levels near 90% that moderate temperature drops.
