According to SVT’s meteorologist Nils Holmqvist, the hot weather is due to a high-pressure front coming in from the south, leading to sun and perfect temperatures for swimming. 

In some areas of southern Sweden, temperatures could reach as high as 30 degrees on Thursday, with a chance of slightly cooler temperatures in coastal areas.

Across large parts of Norrland, cloudy weather is expected, with temperatures of 15-20 degrees on the coast, and lower temperatures expected further inland. In the mountains, rain is forecast.

The high-pressure front is likely to have moved over Sweden by the beginning of next week, resulting in possible thunderstorms.
