**Clear, sunny conditions under high pressure are positioning London's maximum temperature near 22–23°C on September 21, 2026, aligning with the market's leading implied probabilities (22°C at 56%, 23°C at 34.5%).** Official Met Office guidance and multiple forecast models indicate dry, mostly sunny skies with light winds, supporting daytime heating without significant cloud cover or precipitation to limit insolation. Early observations show temperatures climbing through the morning, with afternoon peaks expected in the low-20s Celsius range. This setup reflects typical late-September anticyclonic patterns over southern England, where subsidence and clear skies favor moderate warming above seasonal averages but without extreme heat. Minor model spreads (some guidance at 21–22°C, others near 23–24°C) create the tight clustering around the top two outcomes, while lower probabilities for 24°C+ or 21°C and below reflect the low likelihood of rapid changes on resolution day. Updated official observations and final daily maxima will determine the precise outcome.

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.
