Trader consensus overwhelmingly favors 13°C as London's highest temperature on March 21, driven by Met Office forecasts confirming a daily maximum of 13°C at Heathrow and central London sites under persistent cloud cover and light winds. Ensemble models from ECMWF and UKMO align on this, reflecting cool Atlantic airflow with no warm anomalies, consistent with March climatology where maxima average 11-12°C. Verified observations so far match, with afternoon readings plateauing near 13°C amid overcast skies. A realistic challenge would require an unforeseen clearance of clouds for extra solar insolation, potentially nudging peaks to 14°C, though model uncertainty bands (plus/minus 2°C) make this low-probability at under 1%.
