I suppose what you got there is an average of averages over multiple years. It absolutely does get that cold: For most of January 2021 the average daily temperature was below 20F in Oslo (21/31 days), dropping as low as 3F average and 0F for the lowest recorded temperature. February 2021 wasn't much warmer, only creeping above 20F in the second half. https://www.wunderground.com/history/monthly/no/gardermoen/ENGM/date/2021-1 https://www.wunderground.com/history/monthly/no/gardermoen/E... https://www.wunderground.com/history/monthly/no/gardermoen/ENGM/date/2021-2 https://www.wunderground.com/history/monthly/no/gardermoen/E...
