Met Office forecasts currently indicate a peak of 30°C for London on August 12 under strengthening high pressure, promoting clear skies, light winds, and daytime heating in air masses running 2–3°C above seasonal norms. Ensemble guidance shows modest spread around this value due to variable boundary-layer mixing and possible thin high cloud, keeping the 30°C and 31°C outcomes tightly contested in trader positioning while 29°C remains a close third. Recent model runs have reinforced the warming trend through midweek, with official updates on steering patterns and insolation the next key inputs that could shift implied probabilities before resolution.

This market will resolve based on the highest 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 highest temperature recorded at the London City Airport Station in degrees Celsius on 12 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest 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.
