Trader consensus on Polymarket heavily favors a lowest temperature of 11°C (39%) or 10°C (27%) in London on May 1, reflecting the latest UK Met Office and ECMWF ensemble forecasts indicating overnight minima in this range under a stable high-pressure ridge. Clear skies will enable radiative cooling after daytime highs near 17°C—climatological average for early May—but light winds and London's urban heat island effect limit deeper chills, keeping 9°C (20.5%) viable while pricing 13°C or higher at just 4.5%. Recent 24-hour model runs have converged here, downplaying sub-9°C odds below 3% amid typical spring variability; the evening Met Office update may prompt final adjustments before resolution via official Heathrow observations.
