Trader consensus on Polymarket assigns a 100% implied probability to 21°C as London's highest temperature on April 27, reflecting official Met Office observations from London City Airport—the market's resolution source—which recorded a maximum of 21°C amid mostly sunny conditions and a high-pressure system. This outcome aligns with post-heatwave cooling after early April records near 26°C in Kew Gardens, returning temperatures to mild late-spring norms (seasonal Heathrow average ~15°C) under light southerly winds and low cloud cover. Model forecasts from ECMWF and UKMO had converged on 20-22°C peaks pre-event, with minimal divergence. Realistic challenges are negligible, as provisional data rarely revises post-quality control, barring sensor anomalies confirmed within days.
