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.
