I can't really recall when there was snow in Oslo for half a year. Some years were nearly snowless. Officially, the winter period in Oslo is 119 days. And well north of the city/further from the sea you can feel proper winter better, sure. Even so close as Lillestrøm it's crisper. But again, nothing unusual by North/central European standards.
