Sweden's capital was basking in sunshine on Friday, with much of the south and centre of the country also baking in temperatures of around 25C.
“It is not impossible that we will reach up to 27 degrees,” Per Holmberg, a meteorologist at the weather institute Foreca told Sweden's Metro newspaper.
“I think it will be the hottest day so far this year in southern Sweden,” he added.
