Pankow, and Mariendorf. Such pools will remain at the normal temperature.

Regular swimmers at the city’s Prinzenbad outdoor pool say that they don’t mind. The city pool opened for the season in April, and on a crisp morning in May, Sabine Gutenmueller, an annual pass holder, took her first dip in the chilly water. The water was 68 degrees Fahrenheit, about 5 degrees higher than the air temperature.

She said it wasn’t as cold as she expected.

Selma Nielsen, another regular at the Prinzenbad, told the Associated Press that she thinks the pool's decision to lower the water temperature was overdue.

“I think it's a good thing, not just because of Ukraine but for the climate,' she said. 'As such, I think it's a step in the right direction.”
