Cooler weather to follow warm spell
Britain will enjoy one more day of unseasonably warm weather before temperatures plunge back into the low teens by Tuesday, forecasters warn.
Sun-lovers made the most of the last of the "barbecue weekend" heat on Sunday, taking to parks and beaches across the country.
Opposite ends of the UK experienced the warmest weather by Sunday afternoon, with Southampton and Aboyne in Aberdeen recording the highest temperatures at 23C.
The Algarve and Rome only managed 21C.
Meteorologists said temperatures were up to 8C warmer than the April average in some places following a protracted dry spell.
Monday's forecast looks dry and bright for London and the south, with highs of 20C. However, Scotland is unlikely to break 11C.
Julian Mayes, senior forecaster for MeteoGroup, the weather division of Press Association, warned of unsettled weather on Wednesday, with possible showers as the cool air moves eastwards.
He said: "Most of the country will have a one-day grace (on Monday) before a fairly large drop. Come Tuesday, there will be a sharp reminder that this is only April.
"The rain will be a welcome break for farmers, who have experienced unusually long dry periods for this time of year," he said.
"While we were seeing similar temperatures to the Mediterranean all weekend, we will drop back down as they keep their spring-like weather."
