THE recent heatwave is the longest the UK has seen since 2013, according to the Met Office.
But a cool front making its way south from Scotland will see temperatures drop to the low-to-mid 20s for much of England from Tuesday, Met Office meteorologist Becky Mitchell said.
It will be particularly cool on the east coast, with temperatures forecast in the high teens to low 20s.
After one of the driest Junes on record, there is a chance of some isolated showers across England this week, Ms Mitchell said.
And added:"Temperatures are going to cool down a bit and we're going to see fresher conditions.
"It will still be very warm, less hot than recently, with the risk across the country for showers.
"A bit of rain could be quite welcome for some people, particularly across the south."
For much of England and Wales, last month was one of the top five driest Junes on record.
Some parts of south-east and central southern England saw just 6% of expected rainfall, according to Met Office provisional figures.
Water companies have urged people to use water sparingly to avoid a potential hosepipe ban as they pump billions of extra litres to meet intense demand.
