Met Office observations from key London stations, including Heathrow and central sites, confirm the highest temperature on April 20 reached exactly 13°C around 1 p.m. local time, aligning with trader consensus at 100% implied probability for this outcome. This reflects cooler post-warm-spell conditions after early April's record 26.6°C peak in Kew Gardens, driven by shifting high-pressure systems and increased cloud cover, with forecast models like the UKV accurately projecting highs near 13–14°C amid typical spring variability. While final data audits are routine, a realistic challenge would require verified evidence of an overlooked higher reading from a compliant station, though historical precedents show such revisions are rare for settled daily maxima.
