Central Park in New York City hit a temperature of 100 degrees Fahrenheit on July 2, the first time since 2012 that the iconic park has reached triple digits. This marks the peak of a severe heatwave affecting the region, with temperatures expected to remain dangerously high through the July 4 holiday.
Temperatures in New York City’s Central Park reached 100°F on Thursday afternoon, according to the National Weather Service and AccuWeather. This is the first time in over a decade that the park has hit triple digits, with the last occurrence on July 18, 2012. The city is experiencing a dangerous heatwave driven by a heat dome over the East Coast and Midwest, with humidity making it feel as hot as 110°F.
Weather forecasts indicate that the heat will persist into Friday, with consecutive days of 100°F possible, a rare occurrence in recent years. The city’s previous stretches of three consecutive 100-degree days occurred only twice — in August 1948 and July 1993. The current conditions have prompted emergency measures, including a heat emergency declaration by Mayor Zohran Mamdani and the activation of cooling centers across the city.
Forecasters warn that the heat will gradually subside by early next week, with temperatures expected to return to normal by Monday, accompanied by thunderstorms and rain. The National Weather Service has issued an extreme heat watch from noon Wednesday through 9 p.m. Friday for NYC and surrounding areas.
