**Forecast consensus from the UK Met Office and supporting models centers on a daytime maximum of 26°C in London on August 1, 2026, under largely sunny conditions with light winds.** This aligns with the market's strongest implied probability at 66.5% for exactly 26°C, while nearby outcomes at 25°C (19.5%) and 27°C (12.5%) capture residual model spread and local urban heat-island variability. Earlier July projections of 30°C+ highs have moderated as high-pressure influences eased and Atlantic flow introduced slightly cooler air, keeping values near long-term August averages of 22–23°C but above recent daily norms. Official agencies emphasize that final recorded maxima can shift with cloud cover or timing of peak insolation, though current guidance shows limited upside risk beyond 27°C. Traders are weighting real-time observational data and ensemble runs ahead of the day's resolution.

This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 1 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.
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.**Forecast consensus from the UK Met Office and supporting models centers on a daytime maximum of 26°C in London on August 1, 2026, under largely sunny conditions with light winds.** This aligns with the market's strongest implied probability at 66.5% for exactly 26°C, while nearby outcomes at 25°C (19.5%) and 27°C (12.5%) capture residual model spread and local urban heat-island variability.
