Recent Met Office and ECMWF model runs indicate a weak high-pressure ridge over southern England with light southerly flow, creating tight competition between 24–26°C outcomes for London’s July 22 maximum. Ensemble spreads remain wide due to uncertain cloud cover and the precise timing of any weak frontal passage, keeping probabilities for 25°C and 26°C nearly even at 24.5% and 27.5%. Historical July averages near 23°C provide baseline context, while traders weigh potential daytime heating under clearer spells against modest Atlantic moisture that could cap temperatures. Updated guidance expected within 24 hours will likely refine these closely matched market-implied odds.

This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 22 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.Recent Met Office and ECMWF model runs indicate a weak high-pressure ridge over southern England with light southerly flow, creating tight competition between 24–26°C outcomes for London’s July 22 maximum.
