**Met Office observations confirm London's highest temperature on March 29, 2026, peaked at 11°C**, as recorded at official stations like Heathrow amid persistent cloud cover and heavy showers that suppressed daytime heating. Trader consensus at 100% implied probability reflects this verified data from automated weather stations, aligning with UKMO and ECMWF forecast ensembles predicting a tight 10–12°C range under a southward-tracking rain band and northerly winds. Typical late-March climatology supports this outcome, with historical highs averaging 11–12°C; scenarios challenging it would require rare post-verification revisions from overlooked manual sites, though provisional maxima rarely change significantly. Final resolution awaits UK Met Office daily summary.
