Fall this year may be record mild, with several heat records measured across the country. But snow and cold Arctic air with more normal temperatures are on the way.
– It has been an unusually mild autumn, we are hitting a record. We will soon see how the past colder days have affected the average temperature, says Jon Jörpeland, a meteorologist at SMHI.
September and October were certainly warmer than normal. But it is November that stands out. Especially the first half, when many heat records were recorded in the country.
Tangled record
On November 6, for example, Gladhammar in Småland broke the Swedish November record of 18.4 degrees, measured at Ugerup in Skåne in 1968.
– We got very mild air from the mainland at that time, which meant we were approaching summer temperatures, says Jörpeland.
The highest temperature surplus of the season has been observed in the upper north, which can also be seen on the snow depth map. On the first Advent, all of Norrland is usually covered in snow.
– Now the snow line passes roughly in Jämtland-Härjedalen and obliquely upwards over Västerbotten. The Norrland coastline still lacks depth of snow. Even in the inland parts of Jämtland, the Storsjö area around Östersund, there is not much snow.

TT: What has contributed to the mild autumn?
– We have had recurring low pressures and southwesterly winds that brought smooth air from the continent. As a result, cold Arctic air has not been able to descend. Only in the last week has the colder air from the north begun to sweep across Scandinavia.
Also in the coming week, more normal November weather is expected, with temperatures around zero in the south and minus degrees in the north. On Monday, most of the rain is expected, but also snowfall from Dalarna and the north.
– We can probably expect periods in the future with some precipitation to pass, says Jon Jörpeland.
