Oslo is 5 deg celsius colder in winter than Amsterdam. You sometimes have sub-0, for them it's a norm.

There is a big difference between 5C-10C and 0C (a Warsaw-native here, which is closer in terms of temperatures to Oslo)

Why would this be downvoted? Is absolutely correct. For example average sub zero temperatures mean that snow eventually turns to ice rather than melting.
