If you're visiting now, the Winterdom runs at the Heiligengeistfeld from 6 November to 6 December 2026. It's a large fair with free entry and individually paid rides; Wednesday is the family day, while the busiest stretch is usually the weekend evening. Santa Pauli starts on 9 November on the Spielbudenplatz, adding a distinctly adult Christmas-market option close to the Reeperbahn.
From 23 November to 23 December, the historic Rathausmarkt Christmas market gives you a very different evening: craft stalls, a carousel and the flying Santa, with no admission charge. It's an easy onward plan after a daytime visit to the Elbphilharmonie, though Saturdays are crowded. My advice is simple: pick one market, not three, and leave time to walk the harbour edge.
For music fans, GET UP Comedy is listed for 2 November at Comedy Club Hamburg on Talstraße, while the November listings also include concerts at the Laeiszhalle and venues around St. Pauli.
