Official observations from London City Airport—the market's resolving station via Wunderground—confirm the lowest temperature on May 1, 2026, reached exactly 10°C, anchoring trader consensus at a 100% implied probability for that outcome. This reflects verified hourly data from standard screened thermometers, consistent with mild spring conditions featuring cloud cover that limited nocturnal radiative cooling overnight. Early May climatology in London typically sees minima around 8–9°C at Heathrow, but a positive Central England Temperature anomaly of +2.23°C through April supported warmer-than-average readings. Scenarios challenging this include rare post hoc data revisions from quality control checks by the Met Office, though settled observations post-midnight make adjustments unlikely.
