Mayor Bill de Blasio on Thursday urged Big Apple residents to “keep it local” and not venture out to Long Island beaches for the upcoming Memorial Day weekend as city beaches remain closed.

“My advice to people is keep it simple. Keep it local. Less is more,” de Blasio said during his daily coronavirus press briefing when asked about city residents who may want to travel to Long Island this weekend for some fun in the sun.

De Blasio, who has repeatedly traveled 11 miles from Manhattan to Brooklyn’s Prospect Park for a stroll with first lady Chirlane McCray amid the coronavirus pandemic, added, “I’m not encouraging people to do a lot of traveling.”

“The beaches all over the region are going to come with lots of restrictions,” he said.

Hizzoner’s comments come after he said that New York City residents should be allowed on Long Island beaches following remarks by Nassau County Executive Laura Curran, who blasted as “irresponsible” the mayor’s decision to keep city beaches closed for the holiday weekend and at least until mid-June.

On Wednesday, de Blasio said he understands why Curran has to put her constituents first during the coronavirus crisis.

The mayor on Thursday expressed more of his concerns about city-goers heading to closed Big Apple beaches this weekend.

“We don’t want people gathering on the beaches,” Hizzoner said, acknowledging that “Memorial Day weekend itself will pose a particular challenge.”

There will be “plenty” of NYPD and Parks Department personnel out enforcing social distancing rules and to make sure folks are not going swimming, de Blasio said.

“We will keep both spreading people out, but if we have to send people off the beach, off the boardwalk if we have to reduce the number of people, we’ll do that,” said de Blasio.

City beaches will be closed for swimming until further notice, but walking, running and exercising on the sand and boardwalks are still permitted.

“I think it’s very important that we go slowly and carefully with the beaches,” de Blasio said. “I think we’re in the right place to say there won’t be swimming.”

State-run New York beaches will be open starting tomorrow for the Memorial Day weekend, but they will be at only 50 percent maximum capacity.

“Those beaches may reach capacity at 10, 11 o’clock in the morning, so that’s something to take into consideration,” Gov. Andrew Cuomo said during his own press briefing Thursday.

“You don’t want to take that ride and find out the beaches are already closed,” Cuomo said.
