Wednesday was another hot summer day across Long Island, the National Weather Service said.

Near 90-degree heat continued Wednesday and also is expected Thursday, the service’s Upton office said.

At least swimmers and beachgoers will have extra time to beat the heat at some Long Island state parks both days, Gov. Andrew M. Cuomo said.

Ocean beaches at Jones Beach, Robert Moses, Sunken Meadow and Hither Hills State Parks, and the swimming pool at Jones Beach, will stay open until 8:15 p.m., according to Cuomo’s office.

During the week, some beaches at Jones Beach close about 7 p.m., for example.

News 12 Long Island meteorologist Matt Hammer called Wednesday’s summer conditions “nice with tolerable humidity and sunshine mixing with some clouds at times.”

The sunshine could be interrupted on Thursday afternoon, when there’s a “small chance of showers,” Hammer said.

The best chance for rain, he said, is Friday with scattered showers and storms.

“There could be a few pop-up, typical summer storms this weekend with a bit more humidity, but it’s not a complete washout.”

Hammer said clear skies Wednesday continue into the overnight hours, with lows in the 70s.

Thursday opens to sunshine but clouds develop throughout the day. Daily highs again threaten to reach 90. The high Wednesday, as of 4:15 p.m., was 89 degrees at Long Island MacArthur Airport.
