“We have made this decision because we wanted to make a contribution to the reduction of gas imports”, said a spokesperson for Berliner Bäder-Betriebe, Europe’s largest communal pool operator.

Berlin’s outdoor swimming pools will be two degrees chillier this summer than in previous years, in what the state operator says is its contribution towards reducing German reliance on Russian gas, reports the Guardian.

Water at the German capital’s 16 gas-heated Sommerbäder, or lidos, which start to open this week, will be kept below the weather-dependent standard temperature throughout the summer season.

Three pools heated by solar power, in the districts of Gropiusstadt, Mariendorf and Pankow, will remain as warm as usual. Last summer the average water temperature in Berlin’s outdoor swimming pools was between 22C and 24C.
