Overview

• Frankfurt’s Bornheim Main‑Bad is holding a public test opening on Wednesday after earlier chlorine issues, with hygiene checks under full load to determine whether another trial on Friday and regular opening next week can proceed.
• Frankfurt’s outdoor pools drew a little over 800,000 visitors in a season the baths chief called mediocre, with several large unheated sites closing in late August due to cold water and only smaller pools remaining open on staggered September dates.
• Hesse operators report generally positive balances despite rain, including about 107,400 visitors at Rosenbad in East Hesse through August 29, plus scheduled dog‑swim events and staged closures in Hanau and Wiesbaden and a one‑week extension in Rüsselsheim to September 7.
• Security staffing remained a tool at busy sites: Neu‑Ulm’s Donaubad used guards on peak days, Weißenhorn authorized extra security but did not deploy it, and Senden brought in security with mostly minor incidents reported.
• Bochum’s Wasserwelten is shifting to indoor operations, with Linden’s last swim day on September 7, Werne open at least to September 9 with possible extension to September 14, Südfeldmark closed August 31 for modernization, and Urban Blue staying open weather‑dependent into the autumn holidays.
