Official observations from London City Airport—the market's designated station—confirm the highest temperature on May 12 reached 17°C, driving trader consensus to 100% implied probability on this outcome. This aligns with Met Office reports of mild spring conditions featuring sunny intervals, light breezes (gusts up to 13 mph), and a cool air mass limiting peaks, consistent with early May climatology where London averages 16–18°C highs. Feels-like temperatures dipped to 12°C amid evening clouds, while overnight lows hit 5°C. With data now finalized via automated meteorological sensors, revisions are highly unlikely barring rare instrument anomalies or quality-control adjustments; traders await no further updates as the market nears resolution.
