Ahead of the July 4 weekend, kids took to Vinmont Veteran Park to enjoy the cool relief of the site’s sprinklers. New York City Emergency Management recommends when outdoors, avoid strenuous physical activity, stay hydrated, stay out of direct sun, wear light clothes, use a hat or sunscreen, and avoid drinks with alcohol, caffeine or sugar.

Other than Riverdale Neighborhood House, pictured, residents can also visit Van Cortlandt Park pool at 242nd St. and Broadway, which is open for free from 11 a.m. to 7 p.m., with a break for cleaning between 3 p.m. and 4 p.m., according to the New York City Department of Parks and Recreation.

Families visited Riverdale Neighborhood House’s pool to immerse themselves in the cool, blue water and the company of neighbors during the heat wave. Every Thursday, the Riverdale Neighborhood House offers limited day passes for any community member to purchase a day at the pool. Aside from the neighborhood house, the New York City Mayor’s Office said in its June 29 plan that the city’s outdoor pools are free and open daily from 11 a.m. to 7 p.m. Public beaches are free and open daily with lifeguards on duty between 10 a.m. and 6 p.m., the mayor’s office added.

People gather inside RSS, which serves as a cooling center. Stark stressed the importance of residents staying hydrated, staying indoors and checking on pets and the elderly when temperatures spike.

Of greater Riverdale’s activated cooling centers, Petco Kingsbridge was perhaps one of the less expected. But, it is a comfortable refuge for pets and humans alike during a heatwave. Former Petco Chief Veterinarian Dr. Whitney Miller said in a 2023 press release it is critical for pet owners to prioritize hydration, recognize the signs of overheating in their furry friends — panting, drooling, weakness, vomiting, disorientation and deep or rapid breathing — and adjust a walking routine for cooler times in the day.

Residents endured sweltering temperatures over the July 4 weekend, reaching up to 100 degrees — the highest temperature the city has seen in more than a decade.

Mayor Zohran Mamdani activated a Heat Emergency Plan June 29, calling the plan unprecedented. This included cooling vans that also provided supplies and wellness checks, more than 2,200 LinkNYC kiosks showing walking directions to cooling centers, and numerous pop-up cooling centers.

The term “heat dome” started floating around social media and news outlets to describe the phenomenon, but David Stark, a longtime meteorologist at the National Weather Service’s New York office, said the temperature increase was more accurately described as a “dangerous heat wave.”

Stark said the earth’s jet streams — winds that circle the globe — created an area of high pressure, both at the surface and in the upper atmosphere. Conditions were made even warmer because of a lack of clouds to cool the air as it sank, and the northeast U.S. being at its typical peak of summer.

Stark said while a heat wave reaching 100 degrees isn’t common, citing that the city hasn’t seen that temperature since 2012, it is a relatively usual occurrence at least once in a summer to have a prolonged heat wave. In this instance, the moisture levels in the air were quite high, and combined with high temperatures made the heat feel worse to the body, impacting its ability to cool, according to Stark.

When the body can’t compensate for how hot and humid it is, that’s when heat stress and heat stroke occurs, Stark said. Call 911 immediately in that situation, Stark said.

New York City Emergency Management said symptoms of heat stroke to look out for this summer are hot and dry skin, loss of consciousness or being unresponsive, nausea or vomiting, trouble breathing, fast and strong pulse, weakness, dizziness, confusion, hallucinations and disorientation.
