Trader consensus overwhelmingly favors 18°C as London's highest temperature on March 18, anchored by the latest Met Office and ECMWF ensemble forecasts projecting a daytime maximum of 17-19°C amid building high pressure and light southerly breezes. Verified model outputs from GFS and UKMO runs over the past 48 hours show tight clustering around this value, consistent with recent observations of mild spring conditions and March climatology where averages hover near 12°C but outliers reach 18°C about 20% of the time. Scenarios challenging this include an intensified warm advection from continental air masses or underforecast solar heating, potentially nudging peaks to 19°C+, though current synoptic patterns and low model spread make such shifts unlikely below 1% probability.
