THE thermometers are set to sharply rise today as the south coast bakes in sizzling sunshine.
With temperatures expected to peak at 26C or higher, Portsmouth City Council has issued safety advice.
People are being urged to keep an eye on the vulnerable, elderly and very young people to make sure they are able to stay cool.
Dr Janet Maxwell, director of public health in Portsmouth, said: ‘It is very important to stay cool in these hot temperatures.
‘Do take a look at the tips we suggest.
‘Sun exposure can be extremely dangerous, leading to heatstroke or sunburn, so while we want you to enjoy the summer we ask that you stay safe by regularly applying sunscreen, having plenty of cold drinks, and staying in the shade as much as possible.’
The fine weather is expected to last until Thursday, with temperatures nudging into the mid-20s.
But as the air warms it could lead to some thundery downpours on Friday.
The Met Office is predicting the weekend to be a cooler affair, with temperatures averaging 21C. Cloudy weather is predicted for Saturday and Sunday could see some rain.
The sunshine is expected to return next Monday.
