Climate is a real differentiator: Luxembourg City — temperate oceanic — mild damp winters around 2–5°c, warm summers near 24°c, and a great deal of grey in between. Sofia — continental at 550 metres in a mountain basin — warm dry summers, real snow in winter, and cold still spells that trap the valley's air for days.
