Summer lingers along the coasts of southern Sweden and on Gotland. Fall has not arrived this late since temperatures began to be recorded.
– It is abnormally late at a lot of measuring stations, says meteorologist Emma Härenstam at SMHI.
In autumn, it happens when the average temperature has been below ten degrees for five consecutive days. In the same way, SMHI determines that it is meteorological winter when the average temperature has been zero or lower for five consecutive days.
Summer also in Falun
Emma Härenstam lists places like Visby and Hoburg on Gotland. SMHI has measured the temperatures there since 1859 and 1879 respectively, and never before has summer lingered for a week into November. Neither in Torup in Skåne, in Landsort in Stockholm’s archipelago or in Borås has autumn been as late as this year.
– It is also interesting that summer stays at Lugnet in Falun. We don’t have as long a series of measurements there, but normally autumn usually arrives there at the end of September, she says.
Late winter in the north
Emma Härenstam notes that mild and moist air from more southern parts of Europe is behind the lingering summer in southern Sweden.
– When I look ahead, it looks like a continued setback for the autumn. At the beginning of the week, we can get temperatures above 14 degrees in parts of Halland and Skåne and up to Kalmar on the east coast.
Winter started a couple of weeks ago in the mountain world of Norrbotten and Västerbotten. It took a big step east around October 20th, but has since been pretty quiet. However, meteorological winter prevails in, for example, Gällivare and at Kiruna airport.
– But even in the north it is warmer than normal, says Emma Härenstam.
