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 15 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. 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 guidance points to a maximum of 29°C in London on August 15 amid lingering high-pressure influence and warm advection from the south, though ensemble spreads and timing of any Atlantic moisture introduce notable uncertainty around the precise peak. Trader positioning clusters tightly on 26–27°C because model runs differ on cloud cover, boundary-layer mixing, and urban heat-island amplification at the official London City Airport site. Subtle shifts in wind direction or the arrival of a weak front could easily drop the daily high one degree, while clearer skies or stronger insolation could push it higher; these variables explain the near-even split between the two leading contracts and why probabilities remain fluid until the final 24–48 hours of observational data.
