Recent forecasts from the Met Office and BBC project London highs of 25–26°C on July 21 under mostly sunny conditions with light northerly winds and minimal cloud cover. This narrow range underpins the closely matched market probabilities for 24–26°C outcomes, reflecting ensemble model spread in peak timing and boundary-layer warming rates. Primary drivers include persistent high pressure favoring clear skies and modest warm advection, tempered by uncertainty in exact diurnal maxima across guidance. Updated runs from major numerical weather prediction centers over the next 48 hours will further constrain resolution criteria based on official observational maxima.
