It is always very chilly in Estonia during the month of Febraury. The last time I was in Tallinn during February was for the Independence Day celebrations in 2018. I remember that Saturday, it was bitterly cold outside, the temperature ranged from -12 to -20 °C that day.
Jõgeva is the coldest place in Estonia. The lowest ever temperature in Estonia (-43.5*C) was recorded here in 1940. A monument to cold weather has been erected on the Piibe Road on the outskirts of Jõgeva.
