Trader consensus on Polymarket has locked in 13°C as the highest temperature at London City Airport station on May 13, 2026, with 100% implied probability, backed by official Met Office and BBC Weather observations showing a midday peak of 13°C followed by persistent light showers and northwesterly winds gusting to 21 mph. These conditions—driven by a cool northerly airflow and extensive cloud cover—have suppressed afternoon heating, with current readings at 10-11°C around 19:00 BST and hourly forecasts projecting further cooling to 7-9°C overnight. While model consensus from the UK Met Office supports no rebound, an improbable late-day clearance of showers and prolonged sunshine before sunset (around 20:50 BST) could theoretically push temperatures higher, though synoptic patterns indicate ongoing instability. Final hourly observations will confirm resolution.
