Recent Met Office forecasts project a maximum of 28°C for London on August 8 under sunny conditions with light winds, aligning closely with ensemble model consensus around 27–29°C amid a broader summer warmth anomaly. Overnight lows near 15–17°C provide a moderate baseline, while high pressure and minimal cloud cover allow daytime heating to build without significant mixing or cooling. Historical August averages near 22–23°C underscore the current elevated pattern, and the narrow spread in model outputs keeps 27°C and 29°C as viable secondary outcomes depending on exact peak timing and urban heat island effects. Traders have priced the market accordingly, assigning the highest implied probabilities to 27–28°C as resolution approaches.

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 8 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.
