Official Met Office observations from key Greater London stations, such as Heathrow Airport, confirmed a maximum temperature of 12°C on April 2, anchoring trader consensus at a 100% implied probability for that outcome as real-time data feeds resolved the market. This matched pre-event forecast models from the Met Office and BBC Weather, which projected highs around 11-12°C amid light cloud, gentle northerly breezes, and the trailing influence of Storm Dave ushering cooler Atlantic air, suppressing intensification potential. Early April climatology typically sees London averages of 12-13°C, rendering this unremarkable. Realistic challenges are minimal but could include rare data revisions from quality control processes identifying sensor anomalies or overlooked peaks at secondary sites, though verification protocols make shifts improbable.
