I was stationed not far from Hamburg in the late 80's while in the army. While it might work in the "warm" sunny season, in Hamburg that would be about mid-late May through August, with anything over 85 beingvery hot. The rest of the year is partly cloudy at best, but usually overcast with a lot of rain. It became 2nd nature to carry your rain gear, and light drizzle (which happened a lot) didn't even phase us. Think Seattle but farther north, meaning even shorter days in the winter. The shortest days the sun didn't come up untilafter 8 and it was dark again by 5. BTW, I'm not whining about it, I actually liked it there and had a great experience.
