Recent Met Office forecasts for London on September 19 indicate a maximum of 23°C under sunny intervals with southwesterly winds and limited cloud cover, positioning 22–23°C as the leading outcomes with combined market-implied odds near 67.5%. Persistent mild Atlantic air masses and a building high-pressure ridge are suppressing significant cooling while moderate humidity and light precipitation chances limit peak solar heating. These conditions align with typical late-September climatology, where daily highs often reach 20–23°C amid transitional autumn patterns. Updated model runs showing slightly reduced cloudiness have reinforced trader consensus around these values ahead of final observational data from official stations.

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.
