Trader consensus on Polymarket heavily favors an 8°C minimum temperature in London at 63% implied probability, closely trailed by 9°C at 31%, reflecting the latest Met Office and BBC Weather hourly forecasts updated this afternoon (May 13, 2026). These project overnight lows stabilizing around 7-8°C after evening temperatures drop from 11-12°C amid patchy cloud, light showers, and easing northwesterly winds that have suppressed daytime highs to 12-13°C during a cool, blustery spell. Urban heat island effects and residual cloud limit radiative cooling, preventing sub-7°C dips despite the northerly airflow; genuine uncertainty persists as clearer skies could tip toward 7°C (7% odds), with fresh model runs expected overnight influencing final trader positioning ahead of official station observations.
