Trader consensus on Polymarket heavily favors a 15°C high in London on April 4, aligning with the latest BBC Weather forecast showing light cloud, moderate 17 mph south-westerly winds, and a daytime maximum of 15°C—mild for early April's climatological average of around 13°C at London City Airport station. This positioning stems from recent model runs, including ECMWF ensembles, indicating a transitional high-pressure ridge over southern UK that boosts insolation and advection of milder Atlantic air, following late March's changeable patterns with drier spells. Partial cloud and low shower risks introduce uncertainty, with 14–16°C clustered outcomes reflecting ensemble spread; Met Office updates on April 3 will provide final refinements before resolution.
