**Forecast models and official guidance indicate a Friday minimum around 16–17°C for London on August 28, 2026, aligning closely with the market’s leading outcomes (17°C at 39.5%, 16°C at 35.5%).** The Met Office projects a nighttime low of 17°C, with hourly guidance showing early-morning readings near 16–17°C under mostly cloudy skies and moderate southwest winds of 10–15 mph. Other ensembles place the minimum slightly lower near 15.5–16°C, reflecting minor differences in how much radiative cooling occurs overnight after Thursday’s thundery activity. Key scientific drivers include the advection of cooler maritime air behind the frontal system, increased cloud cover that limits longwave radiative loss, and sustained winds that mix the boundary layer and suppress surface cooling. Dew points in the mid-teens Celsius further constrain how low temperatures can fall. Small variations in cloud breaks or wind timing between model runs explain the tight spread between 16°C and 17°C, while lower-probability outcomes (15°C or below) would require clearer skies and lighter winds than currently expected. Updated forecast runs over the next 24–48 hours will provide the clearest signal ahead of market resolution.

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.
