How The Month Feels
May gives Hamburg a port-city pulse, especially around the Rathaus and the Hafengeburtstag waterfront. By late afternoon, the city still feels active enough for museum time before an evening at Thalia Theater.
What To Lock In Early
Reserve Hafengeburtstag-related stays, harbor cruises, and any International Garden Show ticketing early if it is scheduled. Leave restaurant choices and daytime museum order open, but keep theater tickets fixed.
