- Earlier this week, it was due to the remnants of the tropical hurricane Zeta, which drew in very hot air.

Now the warm weather is partly due to the fact that we have a low pressure that moves on northern runways and gets warm air, but also because it has been windy, says SVT's meteorologist Nils Holmqvist.

That the wind gives us milder weather than usual is due to the so-called blow-drying effect.
