Met Office and BBC Weather forecasts pin London's highest temperature on May 15 at 13–14°C, fueling the near-even trader split with 30.5% implied probability for 13°C and 29.5% for 14°C. Persistent northwesterly winds usher in cooler Atlantic air, while extensive cloud cover and scattered light showers—peaking at 30% chance midday—limit solar heating, keeping peaks below seasonal norms of 17–18°C. Hourly projections show a 3pm maximum around 13°C under cloudy skies, with gusts to 21 mph adding a chill. Model consensus from recent ECMWF and GFS runs reflects this, though brief sun breaks or shower timing could tip the balance; watch overnight updates for refinements ahead of observations at Heathrow or central stations.
