Recent Met Office guidance highlights sunny conditions and a warming trend across southern England, positioning London for a daytime maximum near 32°C on August 9, with overnight lows around 18°C. This aligns closely with ensemble model consensus showing modest high pressure and southerly flow, though slight variations in cloud cover or boundary-layer mixing could cap the peak at 31°C or push localized readings slightly higher. Historical August averages near 22°C underscore the current anomaly, while urban heat-island effects at official stations add minor upward bias. Traders weigh these factors against forecast uncertainty ranges typical 24–48 hours ahead, with the next model updates likely refining resolution criteria for the recorded high.

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 9 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.
