Labor Day lands on September 7 this year, which hands Long Island one last three-day weekend before the school buses take the roads back. The Island is treating it accordingly. One of the oldest powwows in the Northeast turns 80 in Southampton, a Nassau village celebrates its hundredth birthday with fireworks over its own harbor, and the man who sings beside Billy Joel at Madison Square Garden plays a free show on the sand at Point Lookout. Here is what is worth the drive between Friday and Monday.

The Shinnecock Powwow turns 80, and it runs all four days

The 80th Annual Shinnecock Indian Powwow fills the Powwow Grounds on the Shinnecock Nation territory in Southampton from Friday, September 4 through Monday, September 7. This is the anchor event of the weekend and one of the largest Native American gatherings on the East Coast, with dancers and drum groups competing for more than $50,000 in prize money, a sunset fire lighting, and rows of food and craft vendors. Gates run Friday from 3 to 11 p.m., Saturday and Sunday from 10 a.m. to 11 p.m., and Monday from 10 a.m. to 6 p.m. The grand entries, when every dancer in regalia enters the circle at once, are the moment to build your day around: 12:30 p.m. Saturday through Monday, with evening entries at 7 p.m. Friday through Sunday. Admission is $20 for adults, $10 for children 5 to 12, seniors and military, and free under 5, with free parking. Eighty years in, it is the rare event that is both a spectacle and the real thing.

Island Park turns 100 with Andy Cooney and fireworks over the harbor

The Village of Island Park was incorporated in 1926, and it is closing out its centennial summer on Saturday, September 5 at Masone Beach. Irish-music favorite Andy Cooney and his band go on at 7:30 p.m., and the night ends with a fireworks show over Island Park Harbor. A village small enough that the beach is the civic center, throwing itself a hundredth birthday party on that beach, is about as Long Island as an evening gets. The village has asked that no drones fly over the show, so leave yours home.

Billy Joel's second voice, free on the sand at Point Lookout

The Town of Hempstead closes its summer concert season Saturday, September 5 at Town Park Point Lookout on Lido Boulevard, and the headliner is Mike DelGuidice, the Long Islander who has spent more than a decade touring with Billy Joel and singing beside him through the Madison Square Garden residency. The day starts at 3 p.m. with food and family entertainment, and DelGuidice takes the stage around 8. It is free, it is on the beach, and if you have ever paid Garden prices to hear him take a verse of an encore, this is the same voice with your toes in the sand.

Korean street food and K-pop, three days in Huntington

Korea Festa returns for Labor Day weekend, running Saturday, September 5 through Monday, September 7 from 12:30 to 7 p.m. each day at Mahanaim, 300 Nassau Road in Huntington, a five-minute walk from the Huntington LIRR station. General admission is free, with tickets sold inside for food and some activities. Expect Korean street food and desserts, live K-pop sets and dance classes, hanbok try-ons, K-beauty consultations, and a petting zoo and pony rides for the kids. Three full days means Monday, when everything else has wound down, still has somewhere to be.

Swing at The Suffolk, strings in East Hampton

Two very different rooms are worth a ticket this weekend. In Riverhead, Big Bad Voodoo Daddy brings its horn-driven swing revival to The Suffolk on Friday, September 4 at 8 p.m., and a big band in a restored 1933 art deco theater is the right pairing. Out east, the Hamptons Festival of Music opens its MainStage season Saturday, September 5 at Hoie Hall at St. Luke's Episcopal Church in East Hampton, with a full orchestra playing Brahms's Serenade No. 2, Vaughan Williams's The Lark Ascending and Mozart's Symphony No. 39. More than 40 musicians drawn from major American orchestras, in a hall that seats a fraction of what they usually play to, is the quiet luxury option of the weekend.

The beach does not close Monday

One more thing before you pack the umbrella away. Labor Day is the traditional end of beach season, but it is not the actual end: the Town of Oyster Bay has said Tobay Beach will stay open with lifeguards every weekend through September, and the ocean is warmer right now than it was in June. Whatever you do not get to this weekend, the sand will still be there next Saturday. The crowds will not, which is rather the point.
