Official Met Office guidance for London on September 6 points to a maximum of 26°C under southerly flow and partial cloud, aligning with the market's 50% implied probability for that exact outcome. Ensemble models show modest spread driven by variable high pressure and limited moisture, keeping the 25–27°C band collectively above 90% probability while capping upside risk from stronger warming. Recent model runs have stabilized around these values with minimal overnight revisions, though final afternoon observations could still shift within the narrow uncertainty range typical for short-range UK temperature forecasts.

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.
