Perhaps basing yourself in the Norway/Sweeden/Finland part of Scandinavia from March to July. From Munich you're still looking at a bit of a trip to those places. Might be better off to focus on going to the likes of Austria, Czech Republic, Hungary, Switzerland instead when you're based in Munich, than station yourself up North to see those three countries later. From November to January, if you want to avoid winter, Greece/Italy is a good bet, should probably try to get to Dubrovnik Croatia too.
