New York’s blistering heat ‘just the beginning’ as coming temperatures could feel over 100

The city that never sleeps continues to sizzle.

New York’s blistering temperatures are only heating up, with the most brutal stretch still on the horizon. The National Weather Service’s heat index predicts Thursday could feel like a scorching 104 degrees.

“Weak high pressure will allow for sunny to mostly sunny skies today,” the weather service tweeted Wednesday. “Hot and humid conditions continue with temperatures expected to reach the mid to upper 90s for most. Max heat index values will be in the upper 90s to low 100s.”

Tuesday kicked off what’s expected to be a historic heat wave in the city, with a high of 89 degrees recorded in Central Park and 94 degrees at JFK Airport, according to the weather service.

And Tuesday was “just the beginning,” the weather service said, noting there’s “more heat and even more humidity on the way.”

The forecast calls for temperatures exceeding 90 degrees in the city every day through Monday. The following four days also have projected highs in the high 80s or low 90s.

New York City’s longest streak of consecutive 90-degree days occurred during the summer of 1953, when 12 such days were recorded in Central Park.

Eight consecutive 90-degree days would account for one of the 10 longest stretches ever in the city. A streak of eight days or longer hasn’t occurred in New York since 2002.

“Drink plenty of fluids and stay hydrated!” the National Weather Service said.

The NWS cautioned that heat-related illnesses could occur.

Mayor Adams says 90 more city facilities will reduce energy use due to the heat wave.

Adams also encouraged New Yorkers to visit pools, beaches and the cooling centers that are open throughout the five boroughs.

The mayor also touted hydration in a video he posted to Twitter on Wednesday.

“Hey, tap into good health,” he said, after filling a water bottle at a sink. “I never head out without my New York City tap water. It’s hot outside. I urge every New Yorker to drink up. Tap water is the best.”

New Yorkers aren’t the only ones sweating it out. Heat waves are not only affecting the United States, but much of Europe as well.
