How The Month Feels
May gives Hannover a steady city rhythm, with Welfenschloss, Waterloosäule, and the museums sharing the day. The balance feels practical rather than polished, especially when rain passes through.
What To Lock In Early
Reserve Niedersächsisches Landesmuseum and Museum August Kestner if you want to shape the day around interiors. Leave Welfenschloss, Heiligers Brunnen, and Waterloosäule open for the clearer stretches between showers.
How to do it
Plan cue
Book timed visits to Niedersächsisches Landesmuseum and Museum August Kestner for the same day, so a rainy stretch stays efficient.
Plan cue
Start at Welfenschloss before midday, then continue to Waterloosäule while the May daylight is doing the heavy lifting.
Plan cue
Add WOK - World of Kitchen only if you want another indoor stop between the landmark visits and a weather-proof afternoon.
