Beach events set for South Florida's Memorial Day weekend amid environmental concerns and increase in sargassum

High-flying stunts and shoreline celebrations are set to draw crowds across South Florida this Memorial Day weekend, with major events planned in Miami Beach and Fort Lauderdale. Despite the festive atmosphere, beachgoers may encounter an unwelcome presence: large amounts of sargassum seaweed washing ashore across the region.

Miami Beach Air & Sea Show

The Hyundai Air & Sea Show returns to Miami Beach on Saturday and Sunday, featuring military demonstrations along the coast. Pilots and parachute teams are expected to perform from 11:30 a.m. to 4:30 p.m. each day, showcasing aircraft and special operations capabilities.

"We train year-round, and we are excited to bring the show to you all this weekend," said Staff Sgt. Johnathan Pemberton of the US Army Golden Knights.

Spectators can expect a range of aerial maneuvers, including high-speed flyovers and slower demonstration passes, according to Major Connor Sherin of the F-35 Demo Team. "Point blank, you are going to see us go real fast, you are going to see us go real slow," Sherin said.

Admission to the beach viewing area is free. Interactive displays will also be available at Lummus Park through 6 p.m. both days.

Fort Lauderdale Beach Party

Up the coast in Fort Lauderdale, the city will host its annual Great American Beach Party near Las Olas Oceanside Park from noon to 6 p.m. Saturday. The event honors veterans and is expected to attract families for an afternoon of live entertainment and activities.

Seaweed and Closures Limit Beach Options

Beachgoers across the region are encountering large amounts of sargassum seaweed washing ashore.

"So many people are coming to enjoy, and I don't know if I had little kids, I don't want my kids going in that," said Miami resident Nelson Palacio.

The algae buildup comes alongside environmental concerns elsewhere. Officials have closed the north beach at Crandon Park in Key Biscayne due to elevated bacteria levels, further limiting options for swimmers.

Visitors expressed disappointment at the conditions. "We came all the way down here for that? Gross. Definitely gross," said Brittany Foreman, who was visiting from out of town.

Still, some beachgoers say they plan to adjust rather than cancel their plans. "I just want to get a tan," said visitor Davette Nutridge. "I probably am not going to get in the water. I might get my feet wet a little bit".

With large crowds expected, officials encourage attendees to plan ahead and be mindful of beach conditions as South Florida marks the holiday weekend.
