Trader sentiment clusters tightly around 9–11°C for London's highest temperature on March 25, driven by the latest Met Office forecast indicating a daytime max near 10°C under a high-pressure ridge bringing mild continental air, tempered by patchy cloud and light southerly winds. Ensemble models like ECMWF and GFS show a spread of 8–12°C, with 10°C edging ahead due to refined boundary layer predictions favoring slight insolation peaks midday. Historical late-March norms average 11°C at Heathrow, but cooler soil temperatures from recent rains add downward pressure, differentiating sub-9°C outliers from warmer tails amid 1–2°C forecast uncertainty from frontal timing shifts. Upcoming hourly updates could sway the closely matched odds.
