London's daily maximum temperature on August 14, 2026, sits near a critical threshold amid a lingering heatwave driven by a strong high-pressure ridge and southerly advection of warm, dry air. Official Met Office guidance points to a peak near 34°C under largely sunny conditions with light winds, while BBC forecasts and some model runs favor 33°C, reflecting minor differences in boundary-layer mixing, potential afternoon cloud build-up, or a weak sea-breeze influence near the Thames. Urban heat-island effects at central stations versus airport sites add further uncertainty to the exact recorded high. With the market split almost evenly between 33°C and 34°C, traders are closely watching real-time observations and any late-day convective cooling that could cap the peak.

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.
