Recent Met Office guidance and ensemble model consensus point to a mild southwesterly flow over southern England on September 14, supporting maximum temperatures clustered around 24–25 °C in London, which aligns with the closely matched market-implied odds. Variable cloud cover and timing of any residual showers from the prior frontal system remain the key variables that could nudge readings one degree higher or lower, while stronger winds or thicker stratiform cloud would cap peaks nearer 23 °C. Historical September averages near 20 °C provide context, yet current guidance shows a modest positive anomaly. Traders will watch the next high-resolution model cycles and Met Office afternoon updates for refinements ahead of the daily maximum observation window.

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 14 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.Recent Met Office guidance and ensemble model consensus point to a mild southwesterly flow over southern England on September 14, supporting maximum temperatures clustered around 24–25 °C in London, which aligns with the closely matched market-implied odds.
