Where I live we usually have that for at least two weeks during winter, and the rest of the time hovering around -10C (for two to three months). We don't have much snow though, and little wind, so it's really not that bad if you are dressed properly.

Man oh man you wouldn't enjoy eastern Europe in the 90s.

Aside from the general post-communism, we had -30C cold snaps.

But yeah, snot freezes at around -18C - I consider this the point at which things become universally unpleasant regardless how prepared you are.

That being said during a cold snap of -22C I saw my neighbours struggle to start their ICE cars while my hybrid just brutally kicked the engine into action.
