This weekend’s weather — the last weekend of summer — should be sunny and mild, according the National Weather Service.

Despite a chilly start to Saturday, highs are expected to reach the mid-70s across the Island, around average for this time of year, said Faye Barthold, a meteorologist with the service’s Upton office.

“We start off the weekend with gorgeous weather,” said Matt Hammer, a meteorologist with News 12 Long Island. “We’ll see sunshine today, at times more of that filtered sun look this afternoon with high, thin clouds.”

The weather service also noted there is a moderate risk of rip currents developing along the South Shore’s ocean beaches through Saturday night.

Overnight temperature will dip into the upper 60s, but not drop much lower, Barthold said.

Sunday will be more of the same temperature-wise, with a chance for rain. Hammer said the air may start to feel a bit muggy, too.

“Tomorrow looks a little bit more interesting, weather-wise,” Barthold said.

Highs are expected in the upper 70s on Sunday, although Barthold said that will vary out on the East End. A slight chance for rain will develop as the day goes on, with showers most likely around 10 p.m., she said.

The chance for rain continues into Monday morning, with morning temperatures around 70 degrees.
