Official Met Office observations from key London stations, including Heathrow Airport and central sites, confirm a maximum screen-height temperature of 13°C on May 6, 2026, under persistent cloud cover and a cool northerly airmass that suppressed daytime heating despite light winds. This aligns with trader consensus at 100% implied probability for 13°C, reflecting verified hourly data releases showing peaks around midday before evening cooling to 10-11°C. Compared to May climatological averages of 16-17°C highs, the cooler conditions stemmed from recent low-pressure dominance over the UK, limiting solar insolation. Scenarios challenging this include rare provisional data revisions during quality control or overlooked outlier readings from peripheral sensors, though Met Office maxima are authoritative and stable post-initial reporting; final daily extremes updates expected shortly.
