Recent Met Office and ensemble forecasts indicate London's overnight minimum on September 17 will likely settle near 11–14 °C, driven by a mild southwesterly flow off the Atlantic, moderate wind speeds that limit radiative cooling, and patchy cloud cover reducing heat loss after daytime highs around 20–21 °C. These conditions align with typical mid-September climatology for the region, where clear spells overnight can produce brief dips but Atlantic advection keeps values from falling below the seasonal average. Updated model runs show little divergence on the overnight low, supporting trader consensus around the 13–15 °C outcomes while leaving limited room for colder surprises unless skies clear more than anticipated.

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.
