Temperatures could reach as high as 34C this week, forecasters say heat wave We were all hoping it might be just around the corner.
Pressure builds up during the week which will lead to this weather getting warmer, they say met office.
The increasing pressure will create stable conditions that will allow temperatures to build up from day to day, becoming hot or even very hot in parts England and Wales.
So when exactly will it be heat wave start, how long will it take and which areas of the country will be the warmest?
Here’s everything you need to know.
When does a heat wave come?
Temperatures are expected to continue to rise throughout the week, with temperatures set to be “well above average” through Friday 17 June.
The average high temperature in June for the whole of the UK is 18°C.
Temperatures in many parts of the UK will exceed 30C and can even reach as high as 34C in some areas.
It is still relatively uncommon for the temperature to reach the mid 30sC in June.
The highest June temperature recorded in Britain was recorded in 1976, when 35.6 °C was reached on 28 June 1976 in Southampton’s Mayflower Park.
How long does the heat wave last?
Unfortunately, the heat wave will not last.
The Met Office says it’s set to get cooler over the weekend.
There may even be heavy rain in the south, which can be heavy or thunderstormy at times, but the north is expected to be dry and dry and light.
This changeable weather is likely to continue into next week, with rain set to begin in most areas of the UK, particularly the north and north west.
Temperatures will normalize for the time of year, perhaps slightly cooler in the north with a chance of stronger winds at times.
What did the Met Office say?
The Met Office’s deputy chief meteorologist Dan Rudman said: “Temperatures will continue to rise throughout the week and will be well above average by Friday, when many parts of the southern half of the UK are likely to exceed 30C and in some places even will reach 34°C.”
“This is the first hot spell this year and it is unusual for the temperature to exceed these levels in June.
“Many areas will also experience some warm nights with minimum temperatures in the high teens or even low 20C overnight.
“The heat is the result of a mix of domestic daytime warming due to high pressure, plus a southerly airflow bringing some of the warm air from the continent to UK shores.”
Has a severe weather warning been issued?
A Level 2 Heat Health Alert has been issued for much of southern and central England, with northern England on a Level 1 alert.
A heat health alert is issued when there are periods of high temperatures that can affect public health.
Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency, said: “Temperatures are expected to hit 30C in some parts of the south on Friday and we want everyone to be sure to enjoy the hot weather when it does arrives and are aware of good health advice for dealing with warmer conditions.
“In hot weather, it’s particularly important to keep an eye on those most at risk, such as the elderly and those with heart or lung problems.
“Watch for signs of heat exhaustion and follow our simple health tips to beat the heat.”
When does hot weather become a heat wave?
A UK heatwave occurs when a given location records a period of at least three consecutive days with daily high temperatures that meet or exceed the heatwave temperature threshold.
This threshold varies by UK county.
