Recent Met Office guidance and ensemble model outputs indicate overnight radiative cooling under mostly clear to partly cloudy skies will likely produce a London minimum of 13–14°C on August 23, explaining the near-even market split (14°C at 32.5 %, 13°C at 29 %). Light winds and limited cloud cover favor the lower end of guidance, while any increase in low-level moisture or urban heat retention could lift readings toward 15°C. These values sit close to the long-term August climatological minimum, with short-range forecast uncertainty centered on precise timing of any weak frontal feature and local sheltering effects rather than large-scale circulation changes. Updated model runs tonight and tomorrow morning represent the next key data points for traders.

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.
