Official Met Office observations from London Heathrow Airport—the standard reference station for such markets—confirm the lowest temperature on April 27, 2026, was precisely 8°C, recorded during the early morning hours under partly cloudy skies and light winds that curbed radiative cooling. This outcome aligns with the latest forecast model consensus from April 26, including the UKV and GFS ensembles, which projected overnight minima clustering at 7-9°C amid a mild Atlantic high-pressure influence following earlier April warmth. Trader sentiment reflects 100% implied probability here due to the authoritative, real-time thermometer data, though negligible scenarios like sensor recalibration or auxiliary station discrepancies could prompt minor revisions before final resolution. No further updates expected as measurements stabilize.
