Currently, the average temperature is 5.1 degrees, making the spring month almost four degrees colder than the new reference period from 1991 to 2020. Even in relation to the average of the years 1961 to 1990, the temperature is 2.3 degrees Celsius lower. Such a negative monthly deviation last occurred almost ten years ago. If the month were the end of the month, we would have had the coldest April since 1973.
