Traders have converged on 21°C as the near-certain outcome for London's highest temperature on September 11, 2026, reflecting real-time Met Office observations and forecast models showing a daytime maximum near that threshold under partly cloudy skies with light southwesterly winds. This aligns closely with the 1991–2020 climatological average high of 20.6°C for the date at London Heathrow, with current conditions featuring stable high pressure, minimal cloud cover during peak heating hours, and no significant frontal systems to alter the thermal profile. Official hourly data indicate temperatures climbing through the late morning and afternoon before moderating, consistent with the market-implied consensus. A realistic challenge could arise from unexpected model revisions, such as prolonged clear skies boosting insolation or a shift in wind direction that reduces mixing and allows localized warming above 22°C at the resolution station.

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.
