The road figure is the lowest estimate for the coming days, not the air temperature. On a clear night the road surface cools below the air, so there can be ice while the air is still above zero — how this forecast is calculated.

These cities have a page of their own. All 309 municipalities are on the map and in its search box — including those not listed above.

The law does not name a date, so the decision rests with the driver: what the law says about winter tyres.

This page was built from the forecast updated 12 Sep. During the forecast season the map updates twice a day; this page updates with it.
