I'll be in Copenhagen and Aarhus for 6 days starting this Wed (23 Aug). With hand luggage only I can take one coat/jacket. In general would a light rain coat or a warmer woolen coat (not water resistant) be more useful? Will just be doing standard city stuff and also visiting Legoland. Night time temperatures seem to be about 10-13 degrees which sounds abit chilly so I was thinking the warmer coat might be better even if not waterproof?
