Recent Met Office and ensemble model guidance points to a maximum of 19–21°C in London on September 20 under building high pressure, with light northwesterly winds and variable cloud that limits strong daytime heating. A cooler air mass arriving from the northwest after Saturday’s milder southwesterlies is suppressing the upper end of the range, while partial clearing in the afternoon supports the central 20°C outcome favored by traders. Resolution hinges on the precise timing of any residual showers and the extent of insolation, both of which remain sensitive to small shifts in the latest model runs.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 20 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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 and ensemble model guidance points to a maximum of 19–21°C in London on September 20 under building high pressure, with light northwesterly winds and variable cloud that limits strong daytime heating.
