Trader consensus on Polymarket prices a 42% implied probability for London's highest temperature reaching 14°C on April 12, closely trailed by 15°C at 30.5% and 13°C at 19.5%, driven by the latest Met Office forecast updated this morning showing sunny intervals with a 14°C peak amid 60% afternoon shower risk, aligning with BBC Weather's 15°C high under light rain and moderate southwesterly winds. This positioning follows a sharp cooldown from the record 26.6°C heat at Kew Gardens on April 8—the UK's warmest early April day in 80 years—replaced by cooler Atlantic air and frontal systems, as evidenced by yesterday's 14.3°C maximum at Northolt. Observational data and model consensus reflect typical spring variability, with final hourly forecasts today potentially refining peak timing before resolution via official stations like Heathrow.
