It depends. Quite often, Germanic countries are grouped with Northern Europe because many of them are located around the North Sea, Latin countries with Western Europe, Slavic countries with Eastern Europe, and Balkan countries with Southern Europe.

Southern Europeans, Italians, Spanish, Greeks also call Germany Northern Europe. It's anything where the weather is generally not as hot (well, this is changing) people are more reserved, more work-focused, or individual, less prominent communal eating, big families etc. It's a real thing that I often hear from Southern Europeans. You could also relate it to Catholic / Protestant split perhaps.
