Official Met Office data from London stations, including Heathrow, recorded a minimum temperature of 7°C on May 15, driving the market's decisive 100% consensus on this outcome. Mild Atlantic airflow and limited overnight radiative cooling under partly cloudy skies prevented colder readings, consistent with May climatology for the region. No frost or cold-air advection occurred to push values lower, and model guidance aligned closely with observations. While minor station-specific variations or post-event data revisions could theoretically shift the official figure, the broad agreement across monitoring networks makes such adjustments improbable.
