Recent Met Office forecasts indicate a maximum of 28°C for London on July 13, supported by ensemble model runs showing continued warm advection under high pressure before a gradual shift toward more unsettled conditions. Recent heatwave peaks near 35°C on July 9 have driven elevated baseline temperatures, but cooling signals including potential thunderstorms and a moderating Atlantic flow are compressing the distribution around 26–28°C. Trader consensus reflects this by heavily weighting 27°C and 28°C outcomes, consistent with historical July variability and the narrow window for further intensification before any frontal passage. Updated model guidance and official briefings in the next 48 hours will likely refine these implied probabilities.

This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 13 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 forecasts indicate a maximum of 28°C for London on July 13, supported by ensemble model runs showing continued warm advection under high pressure before a gradual shift toward more unsettled conditions.
