Met Office forecasts and supporting model runs position a 20–21°C high as the most probable outcome for London on September 18, driven by mild southwesterly flow, partly cloudy skies, and limited daytime heating under increasing afternoon cloud. Current conditions show temperatures near seasonal mid-September averages, with light rain or drizzle possible late in the day but little risk of significant warming or cooling. The 56% market-implied probability for exactly 20°C reflects tight consensus across official guidance and ensemble spreads, while the 30% share for 21°C accounts for minor upward adjustments in some short-range updates. No major forecast revisions have emerged in the past 24 hours to shift this positioning.

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 18 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.Met Office forecasts and supporting model runs position a 20–21°C high as the most probable outcome for London on September 18, driven by mild southwesterly flow, partly cloudy skies, and limited daytime heating under increasing afternoon cloud.
