Latest Met Office guidance and ensemble consensus, including ECMWF runs, drive the tight clustering around 25–26°C by forecasting a maximum of 25°C for London on July 26 under persistent high pressure. Light winds, limited cloud, and subsidence warming support afternoon peaks near this range, while modest Atlantic influences, possible thin high cloud, and urban heat-island effects create the narrow spread between 24°C and 27°C outcomes. Historical July variability and typical 1–2°C model uncertainty at 48-hour lead times keep probabilities closely matched, with fresh model updates expected to refine the distribution before 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 26 Jul '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.Latest Met Office guidance and ensemble consensus, including ECMWF runs, drive the tight clustering around 25–26°C by forecasting a maximum of 25°C for London on July 26 under persistent high pressure.
