Britain is headed for another scorcher this week with the mercury set to reach up to 34 degrees.
The warmer weather started to creep back in across south east England on Sunday with temperatures climbing to 27 degrees by 3pm.
High pressure will see peak temperatures continue to rise and could even push thermometer readings into the mid 30s once more.
Last month, the UK recorded temperatures of over 40C for the first time ever and it appears the summer heatwaves are not over yet.
The sunshine is expected to return this week with the Met Office predicting highs of 28C on Monday gradually heating up into the weekend.
By Wednesday, the south should see highs of 31C creeping up to 34C by the beginning of next week although this depends on a possible cold front which could dampen things.
Parts of the UK could see more heatwave conditions for three days or more, according to the national weather agency.
Higher than average temperatures are also expected for "many areas of the UK" with further details from the Met Office detailed below according to region.
North England
North West England is expected to remain dry and fine this week and turn increasingly warm over the coming days.
Highs of 24C are forecast on Monday heating up to 25C on Tuesday. This is set to continue with plenty of sunshine throughout the week reaching 26C by Friday.
