Official Met Office observations from key London weather stations, including Heathrow and St James's Park, recorded a maximum temperature of 12°C on March 27, driving near-unanimous trader consensus at 99.9% market-implied probability. This aligns with prevailing cool, unsettled conditions across southeast England, featuring cloudy skies, light showers, and northerly winds suppressing highs amid a broader pattern of below-average spring temperatures influenced by lingering Arctic air masses. Short-range forecast models from the UK Met Office and ECMWF had converged on this outcome in the preceding 48 hours, with no deviations in verified data. Scenarios challenging this—such as a late-reported outlier from a peripheral station or measurement revision—remain highly improbable given standardized recording protocols and quality controls, though final data ratification is pending.
