I just checked the weather forecast for Helsinki next week.
The weather has been around 0 degrees recently, but just as I arrive, the forecast says the skies will be blue and the temperature will be -10 degrees or lower.
The coat I was planning to take is ok for around -3, but I might have to take something a bit warmer, because I have to get from the airport to my hotel in Helsinki before I can buy warm clothes there.
