Bo Sandström is with the fire brigade in southern Älvsborg, a region around Borås in western Sweden. He tells Radio Sweden that some fires in the area started from people burning grass and yard waste during the Easter holiday.
Sandström say this happens annually only now, it is too dry to do so.
"It is usually very dry on the surface of the ground, but now it has gone down through the layers in the soil and it is really, really dry deep down in the ground, and that makes it worse for us," Sandström says.
According to the Civil Contingencies agency MSB, it is unusually early for dry conditions to be causing problems in Sweden.
