**Forecast models from the Met Office and other agencies project an overnight minimum near 11–13°C for London on September 20, 2026, under clearing skies and light northwesterly winds that favor radiative cooling toward dawn.** Trader consensus clusters around 13–15°C because London's urban heat island typically adds 1–3°C above rural readings, while dew points near 9–11°C and variable cloud cover introduce uncertainty in exact cooling rates. Recent days have seen minima of 10.8–16.5°C amid a warm spell, but tonight's calmer conditions and high pressure support the lower end of expectations. Resolution hinges on official station data, with any stronger winds or residual cloud potentially lifting the low into the mid-teens.

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.
