Long summer evenings
Between May and August there is plenty of light until after 21:00! You can arrive tired from a flight in the late morning, rest a bit and still have an opportunity to go for a tour without having this feeling that your day was wasted.
Shop first, tour after
On the same note, maybe you’re the kind of tourists who prefers to go shopping or visit a museum in the morning.
Stay away from the crowds
In the evening, Berlin is more relaxed. There are less people in the streets, and people who work in the centre have gone back to their homes. There is a more relaxed atmosphere and more space to enjoy the sites.
Tour in the cool afternoon hours
I heard this Berlin joke once. It goes: summer is the most beautiful week in the year… Unfortunately, in the last few summers this joke stopped being funny, it gets warm, very warm. An evening tour when the temperatures are dropping can make your walking tour a lot more enjoyable
Best light for photography
And last, but not necessarily least, buildings simply look different in the evening when the sun is shining from a different direction.
