Official Met Office observations from London Heathrow Airport—the standard reference for such markets—confirm the highest temperature on May 11 reached exactly 12°C, amid persistent low cloud, cool northerly winds, and an unstable polar air mass that capped daytime heating. This aligns with pre-event consensus from UKMO and ECMWF models, which forecasted subdued maxima below the mid-May climatological average of 16–17°C due to high pressure to the north blocking warmer southerly flow. Trader sentiment reflects this skin-in-the-game validation of verified data, with 100% implied probability. Realistic challenges are minimal post-event but could include rare data revisions from quality control or disputes over station selection (e.g., St. James's Park vs. Heathrow), though official reporting timelines indicate stability. Next hourly/daily summaries expected within 24 hours.
