Spring Break Miami now has a buzz-killing curfew — courtesy of the coronavirus.

Officials are closing the most popular city beaches at 5 p.m. daily to keep partying college students from spreading the contagion, Miami Beach Mayor Dan Gelber and City Manager Jimmy Morales announced Saturday.

The move is one in a host of measures the city is taking to limit large gatherings.

“It would be irresponsible for us not to limit crowd sizes in these public areas. Not only for our residents and visitors, but for the health and safety of our first responders,” Gelber said in a statement.

Miami Beach has also banned restaurants and nightclubs from hosting more than 250 people at a time and has reopened sections of Ocean Drive that are typically closed to accommodate larger spring break crowds.

Police will be deployed to enforce the beach curfew between Seventh and Tenth Streets, with officers also stopping large groups from gathering at the beachfront Lummus Park.
