Official hourly observations from London City Airport—the market's resolution station—confirm the highest temperature on May 7, 2026, reached 14°C (57°F) around midday to early afternoon, amid mostly cloudy skies, light easterly winds up to 14 mph, and no precipitation. This aligns with a cool air mass over southeast England, suppressing typical May highs of 17–18°C under the influence of persistent cloud cover and stable atmospheric conditions tracked by the Met Office. Trader consensus at 100% implied probability on 14°C reflects verified surface data from synoptic reports, with negligible risk of revision barring rare quality-control anomalies like sensor recalibration. Final Met Office daily summary expected soon could provide confirmatory detail.
