It's also funny how Finland has a concept of "thermic spring", which is defined by the temperature no longer dipping below 0° C, and the term doesn't exist in English because the definition wouldn't work in the climate of most of the English-speaking world.
replyThis a common thing shared with the Nordics. The English term would be “meteorological spring”.

The definition would certainly work in English countries, seeing it is just 0 to 10 degrees Celsius average over the course of a week (and after 15th of February).
