The heatwave threshold in England generally ranges from 25C to 28C.

In order to be classed as a heatwave, the temperature must reach this average over three days – meaning June 14 could be a mini heatwave.

Widespread temperatures could reach between 26C and 27C across large parts of southern England, the Midlands and some areas of the north.

The highest temperatures are expected to be seen in London, with the mercury peaking at 30C and 31C, according to wxcharts.com.

The ‘home counties’ surrounding the capital could experience 29C, while Kent could also see the mercury rise to 30C.

In the West Midlands region, the temperature is forecasted to rise to around 26C and 27C.

But the temperature is set to be cooler in the south west of England, namely Devon and Cornwall, where it will peak at 24C and 23C respectively.

Areas of northern England could see average temperatures of 21C to 22C, although some parts could peak at 23C.

In its long range forecast from June 7 to June 16, the Met Office said: “The unsettled weather of previous days is expected to continue at least through the start of this period, with many – if not all – areas seeing showers or longer spells of rain, and occasionally strong winds.

“At first, wet weather may be focussed across the south of the UK but it looks like this focus will fairly quickly shift northwards during the first few days.

“Towards the middle of June, there is an increased chance that high pressure will become more dominant, at least in the south.

“This would result in some longer periods of drier weather, although unsettled spells remain likely.

“Following a rather cool start to this period, there is a greater chance of warmer spells towards mid-June.”
