Recent Met Office and UKMO model runs point to an afternoon high of 21–22°C in London on September 24 under building high pressure, southerly flow, and mostly clear to partly cloudy skies with light winds. This consensus underpins the near-even market-implied odds on those two outcomes, as traders weigh the balance between peak insolation and modest cooling from variable cloud or boundary-layer mixing. Ensemble spreads show limited potential for 23°C if mixing is weaker than expected, while stronger northeasterly influence could cap readings at 20°C. Updated model guidance and any late adjustments to cloud cover or advection ahead of the 24th will be the key near-term drivers of shifts in trader positioning.

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.
