Enjoy the long holiday weekend with parades, performances, flicks, fried food and lots more

IT’S time to pack up the beach towels and take your final sips of rosé, because Labor Day weekend has arrived, marking the unofficial end of summer. Luckily, there’s plenty going on in the city to help you send off the season in style. From outdoor concerts to art exhibits to rollicking cultural celebrations, here are the happenings that are sure to keep thoughts of autumn away — at least for the next three days.

Nights at the opera

Class up your weekend by taking in a little opera with free screenings of filmed performances at Lincoln Center Plaza — thanks to the Metropolitan Opera’s Summer

HD Festival (1). Arrive in time, and you can claim one of the nearly 3,000 seats provided. On the schedule: “Un Ballo in Maschera,” Saturday at 8 p.m.; “Der Rosenkavalier,” Sunday at 7:15 p.m.; and “Madama Butterfly,” Monday at 8 p.m. Free. Lincoln Center Plaza at Columbus Ave.; MetOpera.org

Keepin’ it wheel

Test out your balance on one of the many onewheeled vehicles provided at the ninth annual NYC Unicy

cle Festival (2) on Saturday and Sunday. For those who’ve already learned the basics, there’s also a jump-rope contest (as in jumping while on the unicycle) and sumo wrestling (you guessed it — also while on a unicycle).

“It’s very much using skill more so than muscle,” says event director Keith Nelson of the wrestling. “Because we’ve seen a 9-year-old

girl throwing off a 25-year-old

fella!” Free. Noon to 5 p.m. Near Castle Williams on Governors Island; NYCUniFest.com

All’s fair

The classic county fair at Historic Richmond Town, Staten Island’s old-timey museum complex, offers all types of family fun through Monday. Among the highlights are unlimited carnival rides, a petting zoo, pieeating contests, and fried food galore. New additions this year include “Food Truck Alley,” down Richmond Road, a beer garden and a display from the Staten Island Car Club. Plus, pony rides have returned (for an additional $5).

“What better way to view our beautiful historic village than by horseback?” says the fair’s organizer, Melissa Perez. $16 for adults, $11 for kids and seniors, free for kids under 30 inches tall. 11 a.m. to 6 p.m. Historic Richmond Town, 441 Clarke Ave., Staten Island; HistoricRichmondTown.org

Still in style
