Trader consensus locks in 13°C as London's highest temperature on March 24, driven by official Met Office observations from Heathrow and central stations, which recorded peaks no higher than 13.2°C amid cloudy, cool conditions with light winds and scattered showers suppressing daytime heating. Historical March norms around 11-12°C align with this mild but unremarkable day, per long-term data from the UK Climate Division. Scenarios challenging this include rare post hoc data revisions from secondary stations or microclimate anomalies in unmonitored urban pockets, though resolution criteria prioritize verified airport readings, rendering shifts improbable as final datasets solidify.
