Official forecasts from the Met Office and other models point to a peak of 21–23°C in London today under mostly clear skies, light westerly winds, and high pressure that favors daytime solar heating with minimal cloud interference. Hourly guidance shows temperatures climbing steadily through the afternoon, with the precise maximum hinging on subtle differences in boundary-layer mixing, urban heat retention, and any late-day cumulus development. The near-even market split between 22°C and 23°C captures this narrow uncertainty range in ensemble outputs, while lower-probability outcomes reflect the low chance of stronger winds or unexpected moisture reducing the high. Updated model runs and station observations will refine the final recorded peak before resolution.

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 5 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.Official forecasts from the Met Office and other models point to a peak of 21–23°C in London today under mostly clear skies, light westerly winds, and high pressure that favors daytime solar heating with minimal cloud interference.
