Current ensemble forecasts from the Met Office and ECMWF place London's May 18 maximum temperature near seasonal norms of 15–16 °C, with the tight clustering of market-implied odds reflecting modest model spread driven by variable Atlantic flow and patchy cloud. Light southwesterly winds and intermittent high pressure are expected to limit daytime heating while preventing sharp overnight drops, keeping the daily peak within a narrow 14–17 °C band. Historical mid-May climatology shows comparable averages around 16 °C, yet recent northerly perturbations have introduced slight cooling potential that traders weigh against stable ridge influences. Updated model runs and official briefings over the next 48 hours will clarify whether cloud cover or clearer intervals ultimately determine the exact high.
