Unless I've been asleep for a long time and it's April 1, this is apparently a serious article.

The mayor’s ordinance, which runs until Aug. 31, bars people from entering or swimming at the city’s public beaches in attire that is not “respectful of good morals and secularism” and that does not respect “rules of hygiene and security.” Offenders risk a fine of 38 euros, or about $42.

Why are burkinis against the rules? “Beach attire that ostentatiously displays a religious affiliation, while France and places of worship are the target of terrorist acts, is likely to create risks to public order,” the ordinance says.
