A high pressure system stationed over Long Island is bringing “tranquil” summer weather to the area on this last weekend of August, the National Weather Service said.

High temperatures for this sunny Saturday will range from 83 to 85 degrees across the Island, just a few degrees above the normal of 80 degrees for this time of year, said David Stark, meteorologist with the weather service’s Upton bureau. Humidity levels will be low this weekend, Stark said, and no precipitation is expected while sea breezes in the afternoon pick up to 10 mph.

Low temperatures on Saturday night are expected to be in the high 60s.

Matt Hammer, meteorologist with News 12 Long Island, said: “It’ll be really hard to find many clouds in the sky this weekend, if any.”

Sunday’s weather will continue on the same pattern, perhaps a degree or two cooler, Stark said. Winds will stay calm, “nothing too strong,” Stark said.

“We have a high pressure system right now that’s typically associated with tranquil weather situated over the region for the next couple of days,” Stark said. “It’ll keep the higher heat off to the south and west, keeping us mostly pleasant.”

Ocean temperatures on the South Shore are in the lower 70s off the East End beaches and in the mid-70s on western Long Island’s beaches, Stark said.

The rip current risk for Saturday is low, Stark said, but Sunday may see higher waves that could create a condition more prone to rip current development.

“It’s great beach weather, boating weather, whatever you like to do outside, this is a great weekend for it, to enjoy the last of summer if you have to go back to school,” Hammer said.

Higher temperatures and humidity will return after the system moves up the coast by the end of the weekend, Stark said, along with an increased chance of showers and thunderstorms Monday or Tuesday.

A mix of clouds is expected for Monday while the weather stays hot, Hammer said, around 87 degrees with increased humidity, possibly leading to a shower late in the day.

Tuesday looks to be sunny, Hammer said, while later Wednesday and early Thursday morning, there’s a chance for a spot shower or thunderstorm before temperatures cool back down Friday into the upper 70s.
