Overview

• Bochum counted about 163,000 swimmers, an 8% drop from last year, and Münster logged 215,000, down by 15,000.
• Bonn reported 340,000 visits, 30,000 fewer than 2024, yet officials called the season very good because only four of five pools were open during renovations.
• Düsseldorf recorded 255,000 guests, up by 5,000, which officials attribute to renovations and new attractions such as a fitness park in Benrath.
• Sportwelt Dortmund described the summer as average with roughly 120,000 visitors, in line with the previous year.
• Many cities, including Düsseldorf, close their outdoor pools on Sunday, as operators also note June heat boosted turnout before weaker July and August weather and Thuringia sites reported around 20% declines with some swimmers shifting to indoor pools.
