Recent Met Office and ensemble forecasts indicate London overnight lows on September 18 will likely settle near 11–12 °C under clearing skies and light westerly winds after Thursday’s rain exits, enabling modest radiative cooling. Model runs show temperatures bottoming out around dawn before daytime warming to 21 °C, consistent with late-summer climatology where minimums average near 12 °C. Trader consensus at these levels reflects stable guidance with limited spread across ECMWF and GFS solutions, while lower-probability colder or warmer outcomes hinge on any late adjustments to cloud cover or wind strength ahead of the next high-pressure build.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
