Trader consensus on Polymarket prices a razor-thin contest between 15°C (36%) and 16°C (34.5%) as London's highest temperature at City Airport on May 7, reflecting Met Office's latest forecast update overnight (May 6), which projects sunny intervals with daytime highs of 16–17°C amid light northerly winds capping heating potential. This positioning stems from yesterday's model runs showing consensus for partial cloud impeding full insolation, following cooler May 6 readings around 14°C; historical early-May averages hover near 17°C, but current high-pressure ridge introduces variability in peak afternoon warmth. Key differentiators include exact cloud evolution and urban heat effects at the eastern City Airport site versus Heathrow's slightly warmer 17°C guidance. Evening forecast refreshes from the Met Office could tip trader sentiment before resolution.
