**Mild southwesterly flow and stable high pressure are keeping overnight lows elevated for London on September 13, 2026, with the latest Met Office and global model guidance (GFS/ECMWF) converging on a minimum of 17–19 °C.** Forecasts show the overnight low into the 13th near 18 °C under cloudy, humid conditions with light rain or showers possible, followed by daytime maxima of 22–24 °C. This places the daily minimum squarely in the narrow 17–19 °C band that dominates the market. The implied probabilities—18 °C at 58.5 % and 19 °C at 33 %—reflect strong model consensus on these values, with only limited downside risk to 17 °C if cooling is slightly stronger than expected. September climatology (average low ~11–12 °C) underscores how unusually mild the current airmass is, driven by persistent warm advection rather than any sharp frontal passage. With resolution just hours away, fresh model runs or Met Office updates will be the key near-term catalysts for any shifts in trader positioning.

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.
