Cooler-than-normal temperatures will continue into the start of the workweek before temperatures creep back up into the 80s for the remainder of the week, according to forecasters.

Overnight temperatures Sunday will dip into the high 50s to low 60s, also about 5 degrees below normal, said Carlie Buccola, meteorologist with the National Weather Service in Upton. Monday and Tuesday will be mostly sunny, with high temperatures in the mid-70s, according to the NWS.

The weather might be close to perfect for late August but gusty winds and elevated ocean waves have made coastal waters dangerous and potentially life-threatening for swimmers and surfers, the NWS said.

A rip current warning that was in effect from 8 a.m. Sunday has been extended through Monday evening as surf heights are expected to reach four to five feet near beaches with winds from the northeast making the conditions even worse, forecasters said. 

Rip currents are fast-moving water channels often occurring near jetties and piers.

“The high-risk currents can pull someone out in the deep ocean waters,” NWS meteorologist John Murray said. “The winds will gradually decrease tomorrow and be noticeably less on all ocean beaches on Long Island.”

Swimmers should stay in lifeguarded areas, Murray said.

If caught in a rip current, swimmers should relax, float and never swim against the current, the weather service advised. If possible, swim in a direction following the shoreline.

Temperatures will remain below normal Monday and Tuesday, before climbing back to the 80s by Wednesday, Buccola said. There's a 30-percent chance of showers on Wednesday night.

Overnight temperatures through Saturday are expected to be in the mid to high 60s.
