Stay Cool, NYC! Extreme Heatwave Forecasted: July 27-29, 2023, Temps Up to 105°F

New York City residents are being urged to take immediate precautions as a severe heatwave is set to grip the city from Thursday, July 27, through Saturday, July 29. The National Weather Service has issued an Excessive Heat Warning, predicting dangerously hot conditions with heat index values expected to reach up to 105 degrees. The advisory will be in effect from 11 AM Thursday to 9 PM EDT Friday.

City officials, including the NYC Emergency Management Department and the Health Department, are advising New Yorkers to “Beat the Heat” by being prepared and vigilant during this period of intense heat and high humidity. The potential health risks from heat illnesses are a significant concern, and residents are encouraged to take necessary steps to stay safe.

New York City Mayor, Eric Adams, emphasized the importance of taking the heat seriously, stating, “Let’s not underestimate the effects severe heat can have on us and our neighbors.” He urged residents to utilize the city’s cooling centers, which will be open across the boroughs starting Thursday, July 27. To find the nearest location and its operating hours, residents can call 311 or visit the City’s Cooling Center Finder.

The estimated heat index values are expected to be particularly intense, reaching 102 degrees on Thursday, escalating to 103 degrees on Friday, and slightly cooler at 99 degrees on Saturday. The city is prepared to extend the operation hours of outdoor pools until 8 p.m. on Thursday, Friday, and Saturday in response to the heat advisory.

To ensure the safety of all residents during the extreme heat, New York City has taken measures to make cooling centers accessible for pets as well. Cooling centers that welcome pets can be found throughout the city, and service animals are always allowed at these centers.

City officials also highlighted the importance of air conditioning during the heatwave. Air conditioning is the most effective way to stay safe and healthy in high temperatures. However, it is acknowledged that some people at risk of heat illnesses may not have access to air conditioning. In such cases, it is crucial to take advantage of public cooling options and follow safety guidelines.

To protect themselves and others during the heatwave, New Yorkers are advised to stay hydrated, limit outdoor activities during peak hours (11 a.m. to 4 p.m.), wear lightweight and light-colored clothing, and avoid prolonged exposure to the sun. The Department of Social Services will be providing shelter and designated cooling areas for those experiencing homelessness during extreme heat conditions.

Furthermore, energy-saving tips are being promoted to help reduce the strain on the electrical grid during periods of high demand. Residents are encouraged to set their air conditioners to 78°F or “low,” and run energy-intensive appliances during cooler hours.

Officials emphasized the importance of recognizing warning signs of heat illness, which include hot dry skin, trouble breathing, rapid heartbeat, confusion, disorientation, dizziness, and nausea. If any of these symptoms are observed, it is crucial to seek medical attention immediately.

New Yorkers are urged to stay informed and sign up for Notify NYC, the City’s emergency communications program, to receive free emergency alerts and updates during the heatwave. Additionally, residents can visit for more information and health tips to stay safe during this extreme weather event.
