Recent forecasts from the UK Met Office and other models indicate a high of 24°C for London on September 7 under mostly cloudy to overcast skies with moderate southwesterly winds. These conditions, typical for early autumn, limit daytime warming compared to clearer September days and align with the market's strong consensus around 24°C (48.5% implied probability) and 25°C (37.5%). Ensemble guidance shows limited spread due to stable pressure patterns and no incoming warm advection, keeping odds for 23°C or lower modest while capping upside risk above 25°C absent unexpected model shifts in the final runs.

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.
