Trader consensus on Polymarket implies a 43.5% probability for London's highest temperature reaching 15°C on April 12, closely aligned with the latest Met Office and BBC Weather forecasts projecting peaks of 14-15°C under sunny intervals and moderate southwesterly breezes. This positioning follows a sharp cooldown after the record 26.6°C heat in southwest London on April 8—the warmest early April day in 80 years—driven by a low-pressure system displacing high pressure and advecting cooler Atlantic air masses, with scattered early showers limiting solar heating. GFS and ECMWF model ensembles converge on these mild conditions near seasonal norms of 12-15°C, though persistent cloud versus clearing skies introduces uncertainty that could tip outcomes toward 14°C or 16°C. Met Office updates expected later today may further clarify peak afternoon temperatures.
