Long Island is in for a pleasant but cool weekend, meteorologists said.

Both Saturday and Sunday will be dry and clear with highs in the low 70s. Western Nassau County could see slightly warmer temperatures, said Joe Pollina, a meteorologist with the National Weather Service’s office in Upton.

Pollina said lows overnight into Sunday will drop into the 50s for the entire Island. The pine barrens may even see temperatures in the upper 40s.

Sunday’s lows into Monday will look similar, said News 12 Long Island meteorologist Matt Hammer.

Such temperatures are a few degrees below the average, Pollina said. This time of year usually sees a high of 76 at Islip.

“At least high-wise, we’ll be slightly below normal,” he said. “The low for Islip is about 60, so we’re below normal there, too.”

As Hurricane Irma makes landfall in Florida, Long Islanders should watch out for dangerous water conditions, the weather service said. In a coastal hazard message put out by the service, meteorologists warned of high rip current risk along the South Shore due to hurricane activity in the Atlantic. The storm could cause rough surf and rip currents on the Island through Sunday.

George Gorman, Long Island deputy regional director for the state parks department, noted that the rough surf conditions on Long Island beaches will not abate for at least a few days because Hurricane Irma will be succeeded by Hurricane Jose.

“Right now, it’s the effects of Irma . . . we’re also, right behind it, going to see the effects of Hurricane Jose,” Gorman said. “These storm systems are Category 3 and 4 hurricanes, and they are extremely large and intense and massive.”

Hurricane Irma forced lifeguards to close swimming at Hither Hills State Park in Montauk due to severe riptides and waves as high as 8 feet, the parks department said Saturday.

At Jones Beach in Wantagh, the hurricane was creating medium to severe riptides, with 5- to 7-foot waves, and the high tide is halfway up the beachfront, the department said. There were no riptides at Robert Moses State Park in Babylon, but the waves were as high as 6 feet.

Lifeguards were keeping any swimmers close to the shore at both Jones Beach and Robert Moses, the department said.

Monday should bring more seasonable weather, with highs expected in the mid-70s. Pollina said the start to the week should also be mostly sunny.

“Monday looks great and a few degrees warmer,” Hammer said.
