**Met Office forecasts for London on August 14 point to a maximum of 33°C under continued high-pressure influence, following a peak near 37°C on the 13th amid the broader 2026 heatwave.** This positions 33°C as the modal outcome in trader pricing, with 32–34°C capturing over 90% of implied probability due to model consensus on modest cooling from reduced insolation and slight increases in boundary-layer mixing. Persistent anticyclonic subsidence, clear skies, and light winds favor strong daytime heating consistent with historical August maxima in southeast England, while the urban heat island effect supports readings at or above the regional average. Recent Met Office updates and amber heat warnings have reinforced expectations around this narrow range ahead of final observational data.

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 14 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.
