-15 is cold wherever you are!
But I know what you mean. In my city, temperatures can drop to -30 in the winter and that lasts for weeks, and people grumble more to themselves than out loud. In our capital, if it's -5 and 3 cm of snow falls, they consider it a natural disaster. And the distance is less than 200 km.
Simple secret is too dress warmly, then most weather is tolerable!
