The average temperature this past winter (December through February) was 4.3 degrees. That ranks as the 16th coldest winter of the 133 winters on record in Fargo Moorhead (records began on January 1, 1881, therefore the first winter has incomplete data, meaning the first winter of record was the winter of 1881-1882).
The last colder winter in Fargo Moorhead was back in 1981-1982 when the average temperature was 3.3 degrees. Other fairly recent colder winters were in the late 1970s. The winter of 1978-1979 the average temperature was 0.6 degrees and the winter of 1977-1978 the average was 2.8 degrees. Those were the two coldest back to back winters since the 1880s. Even with such a cold winter being recorded, no record lows were set. Of interest, the coldest temperature of winter was just -25 degrees on January 2 which is 3 degrees above the average coldest temperature recorded in a year locally.
There have been colder winters, but if you are under 30, it was the coldest winter in your lifetime.
