Trader sentiment clusters tightly around 9–11°C for London's highest temperature on March 25, driven primarily by the latest UK Met Office and ECMWF ensemble forecasts implying peaks in this range amid a weak frontal system ushering cooler Atlantic air. Differentiating factors include cloud cover persistence—persistent stratus favors 9°C by suppressing insolation, while brief midday breaks could boost to 11°C via enhanced solar heating on southerly winds. Historical late-March highs average 10–11°C at Heathrow, but current 850hPa temperatures 2–3°C below seasonal norms tilt odds toward the lower end, with 00Z model updates pivotal for refinement.
