Latest Met Office forecasts peg London's highest temperature on March 25 at around 10°C, driving trader consensus with 32% implied odds for that outcome amid a cluster of 9–11°C probabilities totaling over 75%. Ensemble models from ECMWF and UKMO exhibit a tight spread, differentiated primarily by uncertainty in afternoon cloud cover and the timing of a weak northerly breeze suppressing highs below seasonal norms of 11–12°C. Recent 12Z runs refined this outlook after earlier GFS projections trended cooler, while low probabilities for extremes reflect minimal risk of Atlantic warmth or polar air outbreaks, per verified upper-air analyses. Traders eye evening updates for potential shifts.
