Recent Met Office and ensemble forecasts indicate a high of 21–23 °C for London on 15 September 2026 under a moderate westerly flow of mild Atlantic air, with partly cloudy skies, light-to-moderate winds, and only isolated showers. This narrow range aligns with the closely matched market prices around 21–23 °C, reflecting model consensus on limited diurnal warming and modest temperature advection. Key differentiating factors include the precise timing and coverage of any residual cloud, boundary-layer mixing depth, and slight variations in surface pressure gradients that could nudge the daily maximum by 1–2 °C. Updated model runs and official briefings over the next 24–48 hours will refine these details ahead of resolution.

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.
