Recent forecasts from the Met Office and other models indicate London’s overnight low on August 27 will most likely settle between 16–19 °C, with the 18–19 °C outcomes commanding the bulk of trader volume. Persistent cloud cover, showers, and a mild southerly flow are limiting nocturnal radiative cooling, while London’s urban heat island effect further supports these elevated minimums relative to surrounding rural areas. Model consensus shows little risk of dropping below 16 °C or rising above 20 °C, consistent with the sharply declining probabilities outside the 17–19 °C band. Updated guidance through the morning will be watched for any late shifts in wind or clearing that could alter the final recorded low at the primary observing site.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 27 Aug '26.
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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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 forecasts from the Met Office and other models indicate London’s overnight low on August 27 will most likely settle between 16–19 °C, with the 18–19 °C outcomes commanding the bulk of trader volume.
