Helicopters are water-bombing the blazes in bone-dry forests.
Ljusdal and Alvdalen, roughly 330km (205 miles) from Stockholm, are among the worst-hit areas. Unexploded shells on a military range pose a risk in one of the fire zones.
Meteorologists issued extreme heat wave warning for the entire nation as one of the hottest and driest summers on record continues.
Firefighters are also battling wildfires in the southern part of Norway.
