Traders have converged on a 20°C high for London on September 20 with near-certainty because official forecasts from the Met Office and supporting models consistently project a maximum around 19–21°C under clear skies, light northwesterly winds, and stable high pressure. This aligns with climatological norms near the 19.5°C average high for the date, with recent observational data from stations such as Heathrow confirming readings peaking near this threshold. Minor model spreads or slight variations in urban heat-island effects could shift the exact recorded value by 1°C, but late-day verification leaves little room for deviation outside the narrow 20°C outcome.

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.Traders have converged on a 20°C high for London on September 20 with near-certainty because official forecasts from the Met Office and supporting models consistently project a maximum around 19–21°C under clear skies, light northwesterly winds, and stable high pressure.
