This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 1 May '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.Trader consensus on Polymarket strongly favors a 24°C high in London on May 1 at 46% implied probability, closely tracking the latest Met Office forecast updated April 30, which projects a daytime maximum of 25°C but hourly peaks of 24°C under sunny skies turning hazy with light south-easterly winds and a low 30% late shower risk. BBC Weather aligns with a 25°C high and 0% precipitation, reflecting model consensus for above-climatological averages (17–18°C) driven by persistent upper-air blocking that suppresses cooler Atlantic influences amid April's warm trend, including recent 21°C today. Uncertainty lingers from potential evening cloud capping peak heating at 23°C (22%), with overnight forecast refinements ahead of official observations resolving the market.
