The intense and unusually early heat wave that has blanketed much of the Northeast for the past week continued on Sunday to scorch New Jersey, where excessive heat warnings or heat advisories were in effect in most of the state, according to the National Weather Service.
Temperatures throughout the region were more than 10 degrees above average on Sunday, according to Joe DeSilva, a meteorologist with the Weather Service. Trenton, the state capital, reached 98 degrees — just two degrees shy of the city’s hottest recorded temperature, last logged in 1952, he said.
The worst of the sweltering heat should be over by Sunday evening, Mr. DeSilva said, though temperatures were expected to remain in the 80s in the coming week.
Officials in numerous communities urged residents — especially older people, homeless people and those with chronic health conditions — to prevent heat-related illness by staying hydrated, using air-conditioning, limiting strenuous physical activity and wearing loose, light-colored clothing. Pet owners should also monitor their animals for signs of overheating, such as excessive panting, drooling and lethargy, officials said.
The state’s Department of Environmental Protection encouraged New Jerseyans to take advantage of the Chill Out NJ tool, an online map of public places where people can find air-conditioning, pools, splash pads, beaches or shady parks.
The lengthy heat wave also prompted officials in some places, including Pennsville Township, Moorestown and Vineland in South Jersey, and Ridgewood, Denville and Butler in North Jersey, to announce mandatory or optional water restrictions, asking residents to refrain from washing their cars or watering their lawns. And at Red Bull Arena in Harrison, a National Women’s Soccer League game between Gotham F.C. and the Washington Spirit on Sunday was moved to 6 p.m. from 1:30 p.m. because of the heat.
