People in Suffolk did their best to cool off from the Wednesday heat that sweated Hampton Roads with heavy humidity in the air.

Families in North Suffolk put on swimsuits and jumped into the Nansemond Swim Club pool in Eclipse, where lifeguard Reagan Nierman, 18, had already finished a few bottles of water before noon during her six-hour shift. She said the heat had been “unbearable.”

“I personally just got back from Oregon where there’s no humidity and I’m really struggling right now,” she said.

Senior lifeguard and manager Rosario Manfred, 20, had spent the morning shoveling in the dirt for maintenance on the nearby fire pit. The humidity did him no favors under nearly-clear skies.

“We’re just trying to stay in the shade and keep things cool,” Manfred said as he finished another bottle of water.

The National Weather Service issued a heat advisory on Wednesday from 11 a.m. to 8 p.m. for all of southeastern Virginia and northeastern North Carolina. Forecasters predicted temperatures in the mid-to-upper 90s, much higher than seasonal average highs recorded at Norfolk International Airport that range from 85 to 87 degrees, according to meteorologist Eswar Iyer with National Weather Service Wakefield.

Temperatures approached the 100-degree record for Aug. 8 highs that was set in 2007, Eyer said. The highest temperature on record for August was 105 degrees in 1918.

Eyer did confirm that a slow-moving cold front should reduce the humidity and temperatures in Hampton Roads for the rest of the week, but only slightly.

“The humidity isn’t going to get that much lower,” he said, describing it as a “slight lowering.” “Temperatures will be slightly lower as well, but there could still be highs around 90 on Thursday and Friday.”
