Official Met Office forecasts for London on August 23, 2026, project a minimum of 14°C under clear skies and light winds, driving the market's overwhelming 99.5% implied probability for that outcome. Radiative cooling overnight, aided by dew points near 10°C and minimal cloud cover, favors an exact low in the 13–14°C range, consistent with model consensus and seasonal norms for late August. Milder southwesterly flow has kept overnight values near or slightly above historical averages around 14°C, with low precipitation risk limiting further drops. Traders price this stable setup heavily ahead of final readings. Unexpected increases in cloud cover, stronger winds, or a shift in air mass could realistically push the minimum outside this narrow band.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the London City Airport Station in degrees Celsius on 23 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the London City Airport Station, available here: https://www.wunderground.com/history/daily/gb/london/EGLC.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
