**Mild, humid southwesterly flow and extensive cloud cover are keeping overnight radiative cooling limited across London on September 13, 2026, positioning the daily minimum near 18 °C.** Official guidance from the Met Office and GFS-based models shows early-morning temperatures bottoming out around 16–18 °C under mostly cloudy skies with light southwesterly winds and high humidity (80–95 %), conditions that suppress the typical clear-night cooling seen in historical September climatology. Recent model runs have trended slightly warmer for the overnight period, with no incoming cold front or clear slot to drive sharper drops, which aligns with the market-implied odds heavily favoring 18 °C (77 %) over 17 °C (17.5 %) or lower. Resolution will hinge on the verified 24-hour minimum from London-area stations; any unexpected clearing or wind shift could still allow a brief dip toward 16 °C, but current observational trends and forecast consensus support the leading outcome.

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.
