Recent Met Office and ensemble model guidance indicate high pressure and light southerly flow will bring mostly sunny conditions to London on September 22, supporting maximum temperatures near 24–25 °C. These forecasts have driven the close market-implied odds between those two outcomes, with modest probability on 23 °C reflecting possible timing of any afternoon cloud or slight cooling from variable winds. Historical September maxima average around 19–20 °C, so the current warm anomaly stems from persistent anticyclonic setup rather than typical seasonal patterns. Updated model runs and official briefings over the next 48 hours will refine exact peak readings ahead of market 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.
