Official Met Office observations confirm London's highest temperature on March 26 reached exactly 10°C at Heathrow Airport, the standard reference station for the city, aligning with trader consensus at 100% market-implied probability. Cool northerly winds and widespread cloud cover suppressed daytime heating, consistent with forecast model guidance from the UK Met Office and ECMWF, which predicted highs in the 8–11°C range amid a broader pattern of below-average spring temperatures influenced by lingering Arctic air masses. While the reading is final from verified automated weather stations, rare challenges could arise from data revisions due to equipment calibration issues or supplemental manual observations from central London sites showing minor discrepancies, though historical precedent indicates such adjustments are infrequent for settled conditions.
