Trader consensus on Polymarket heavily favors 13°C or below at 73.5% implied probability for London's highest temperature today, driven by the latest Met Office and BBC Weather forecasts projecting a midday maximum of 13–15°C under sunny intervals following morning rain clearance. This cooler turn follows the record early April heatwave peaking at 26.6°C on April 8, as a low-pressure system ushered in Atlantic air masses, persistent cloud cover, and isolated showers—conditions that limit solar heating per standard atmospheric dynamics. Yesterday's Northolt observation of 14.3°C aligns with seasonal norms of 12–14°C, but moderate south-westerly winds (15 mph gusting higher) and shower risks temper upside potential. Hourly updates from official sites like Heathrow will refine resolution as the day progresses.
