Just to provide some counterpoint to this: I regularly go with my kids in the winter weekends, and aside from the Wellenbad ("wave pool") in Görlitzer Park, which had a plumbing problem once when I went, I've never run across randomly closed pools. We didn't go much last winter since they'd lowered the temperatures because of the war in Ukraine and rationing of gas, but we went a lot the year before and a couple times already this year. They've never been painfully crowded -- in fact, usually the opposite, usually pretty empty. We've gone in Kreuzberg, Neukölln, Lichtenberg and Schöneberg.
