PARIS (AP) 鈥 Cries of 鈥淚t is warm!鈥 rang out across the Seine on Saturday morning as Parisians jumped into the river 鈥 legally 鈥 for the first time in more than 100 years.

Public swimming was , including two newly built wooden decks near the Eiffel Tower and the 脦le Saint-Louis in central Paris. Before sunrise, a municipal officer skimmed away the last few patches of algae with a fishnet. Soon after, a line of eager Parisians formed, towels in hand, waiting for their chance to jump in.

Woos and cries of joy echoed across the riverbanks as the first swimmers entered the emerald-green water.

Every swimmer wore a bright yellow lifebuoy tied around their waist, part of strict safety measures enforced by a dozen lifeguards in high-visibility vests. The current was weak, just enough to tug gently at their limbs 鈥 a reminder that this is still a living, urban river.

鈥淚t鈥檚 so nice to swim in the heart of the city, especially with the high temperatures we鈥檝e been having lately,鈥 said Amine Hocini, a 25-year-old construction worker from Paris. 鈥淚鈥檓 surprised because I thought it was going to be cooler and in fact, it鈥檚 much warmer than I thought.鈥

Swimming in the Seine had been illegal since 1923, with a few exceptions, due to pollution and risks posed by river navigation. Taking a dip outside bathing areas is still banned for safety reasons.

From the deck, tourists and morning joggers stopped to watch. Some applauded as swimmers climbed up the steel ladders, grinning and dripping. Others, like Fran莽ois Fournier, remained skeptical.

鈥淚 won鈥檛 risk it quite frankly,鈥 said Fournier, who lives atop the riverbanks and observed the scene from a bridge above. 鈥淚鈥檝e seen things you can鈥檛 imagine floating in the Seine, so I鈥檒l wait for it to be really squeaky clean.鈥

Floating debris still bobbed here and there 鈥 a stray leaf, a plastic wrapper 鈥 but the smell was barely noticeable: no strong sewage odor, just an earthy, river-like scent.

鈥淭his is so chic, to swim in the Seine, next to 脦le Saint-Louis,鈥 said Lucile Woodward, 43, a resident. 鈥淭here are some apprehensions, of course, any time you go to swim somewhere, but I think this is one of the most tested areas in the whole world now. I don鈥檛 think the town hall can allow herself to have any problems.鈥

She added with a laugh: 鈥淢y skin is OK.鈥
