London's maximum temperature on September 7, 2026, has aligned with official Met Office forecasts and observational data showing a daytime high of 25°C under mostly cloudy skies with light westerly winds. Multiple real-time reports, including station readings near 21–23°C by evening and model consensus from sources like the UK Met Office, confirm this peak under stable atmospheric conditions typical for early September in the region, where average highs hover around 21°C. Traders have placed near-certain weight on this outcome given the tight alignment between forecasts and live measurements, with resolution hinging on verified daily maxima rather than models. Minor shifts could arise only from post-day data revisions or localized microclimate variations at monitoring sites, though current evidence leaves little room for deviation.

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 7 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.London's maximum temperature on September 7, 2026, has aligned with official Met Office forecasts and observational data showing a daytime high of 25°C under mostly cloudy skies with light westerly winds.
