Latest Met Office and BBC Weather guidance positions London's lowest temperature on April 15 around 11°C, matching the market's leading implied probability of 38.5%, as persistent overcast skies and southerly breezes of 10-16 mph from an incoming frontal system curb radiative cooling overnight into early morning. This follows a record-breaking warm early April spell exceeding 20°C averages, now yielding to unsettled patterns with light rain and gusts up to 30 mph that maintain mild minima above typical 7-8°C historical April norms at London City Airport. Ensemble model consensus supports 10-13°C range, though slight shifts in cloud breaks or wind could adjust by 1-2°C; observations throughout April 15 will confirm resolution.
