This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 11 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Met Office's midday forecast update pegs London's highest temperature today at 14°C around 3-4pm under sunny intervals and moderate south-westerly breezes, driving trader consensus to 61.5% implied probability for that outcome. This follows the breakdown of a high-pressure system after an extraordinary early April heatwave, with peaks over 26°C on April 8 near Kew Gardens—well above the 12-15°C seasonal norm—now replaced by cooler Atlantic air and low-level clouds limiting insolation. Yesterday's regional high of 14.3°C at Northolt sets a recent benchmark, while 28% odds on 13°C or below account for shower risks and model uncertainty in boundary layer mixing. Hourly observations from Heathrow and City Airport will determine the official peak before market close.
