Recent Met Office and complementary model guidance position a 23°C high as the leading outcome for London on September 21, driven by persistent high pressure, light westerly winds, and mostly sunny conditions expected to deliver above-average warmth without significant cloud or precipitation. Official forecasts converge on a daytime maximum near 23°C, with some runs showing 22°C depending on exact timing of any afternoon cloud build-up, while historical September averages of around 20°C provide context for the mild anomaly. Traders appear to weigh the narrow spread between 22°C and 23°C outcomes most heavily, reflecting typical forecast uncertainty ranges of 1–2°C this close to the event. Updated guidance from monitoring agencies later on September 20 could refine probabilities ahead of 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 21 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.Recent Met Office and complementary model guidance position a 23°C high as the leading outcome for London on September 21, driven by persistent high pressure, light westerly winds, and mostly sunny conditions expected to deliver above-average warmth without significant cloud or precipitation.
