After the winter solstice, it turns. December 21 is the longest night of the year, but then expect more light, even if it is slow at first.
More light awaits around the corner. This is how the length of days changes during the year.
Looking for bright spots in the winter darkness? Soon, you can at least wait longer days.
At 11:02 a.m. on Monday, December 21, the dark season ends.
– At the winter solstice, the Earth’s axis is mostly tilted away from the sun. That’s when we have the shortest day and the longest night, that is, the darkest day of the year, says Linnea Rehn, a meteorologist at SMHI.
– But after this he turns around and the days gradually lengthen.
However, the light does not rush.
– At first, it’s just a few extra minutes a day. Then the curve increases exponentially and, at most, during the spring, the length of the day increases by more than ten minutes per day, says Linnea Rehn.
By the new year, the length of the day has increased by about five minutes in Svealand and Götaland, and roughly double in Östersund. Higher up in the country, however, it takes longer before the power returns.
– The polar night will prevail until January 10, says Linnea Rehn.
On the other hand, the rise is faster once it starts.
– In the north it goes from the polar night to the other extreme which is the midnight sun. Immediately after the winter solstice, there is not much difference, but during the spring, Norrland turns and flees, says Linnea Rehn.
In southern Sweden, November offered fewer hours of sunshine than normal and the dark trend has continued into December. Longer days certainly don’t guarantee beautiful weather, but the chances of the sun shining increase at least as darkness now slowly recedes.
Light and dark during the year
Solstices occur twice a year and are the times when the earth’s axis leans the most toward or away from the sun.
The winter solstice marks the day when the day is shortest and night is longest.
Around the winter solstice, the sun does not rise at all over the horizon north of the Arctic Circle, which is called polar night. But total darkness does not prevail throughout the day, during the day it is a little brighter.
At the summer solstice, the night never really turns black anywhere in Sweden. During the night there is a twilight that immediately turns into dawn. From the Arctic Circle and north, the sun does not set at all, which is called the midnight sun or polar day.
