Official meteorological observations from the UK Met Office confirm that London recorded a maximum temperature of 20°C on May 20, driving the market's near-certain consensus on this outcome. This aligns with typical mid-May climatological baselines for southern England, where daily highs under stable high-pressure systems often reach 18–21°C with minimal cloud cover or Atlantic moisture advection. Recent model runs from the Met Office and ECMWF showed consistent warming trends through the period, with no significant frontal systems or wind shifts to suppress peaks. While minor microclimate variations at urban stations could theoretically prompt minor revisions, historical verification processes rarely alter daily maximums by more than 1°C once finalized.
