Latest Met Office forecasts indicate a maximum temperature around 16-17°C for London on April 16, driving trader consensus with 17°C at 39% implied probability amid light rain and cloudy skies. This follows an early April heat spike peaking at 26.5°C in Kew Gardens on April 8—one of the hottest April days in 80 years—before a frontal system ushered cooler Atlantic air, westerly winds, and reduced insolation from persistent cloud cover. ECMWF and GFS model ensembles show tight agreement on mild conditions, above the April historical average of 14°C but capped by showers. With resolution nearing via official observations at Heathrow or central stations, minor shifts remain possible from overnight clearing or timing of precipitation.
