NYC Agencies Warn of Extreme Heat, Urge Precautions as Heat Index Nears 105°F Friday

New York City is bracing for a severe heatwave on Friday, with the heat index expected to reach a scorching 105°F. Alongside the intense temperatures, an Air Quality Health Alert has been issued, indicating an “Unhealthy for Sensitive Groups” Air Quality Index of 101. City officials are urgently advising New Yorkers to take immediate precautions to stay safe during this dual threat.

Mayor Eric Adams assured residents that the city is “deploying every tool and resource available to keep New Yorkers safe,” including opening cooling centers and coordinating emergency responses. He stressed the importance of individual preparedness, urging everyone to “make a plan to stay cool and hydrated, limit outdoor activity during peak heat hours, conserve energy where possible, and look out for one another.”

NYC Emergency Management (NYCEM) Commissioner Zach Iscol echoed these warnings, emphasizing the seriousness of this fourth heat emergency of the season. He implored New Yorkers to “take the heat seriously” by staying hydrated, avoiding strenuous outdoor activities, and seeking out cool places in their neighborhoods.

Dr. Michelle Morse, Acting Commissioner of the Department of Health and Mental Hygiene (DOHMH), highlighted the silent danger of extreme heat, noting that “Each year, over 500 lives are lost to extreme heat.” She strongly recommended that residents without home air conditioning utilize cooling centers, libraries, or shopping malls to escape the heat. Dr. Morse also urged people to check in on vulnerable neighbors and loved ones, especially older adults, as a quick call or visit could save a life.

In response to these escalating conditions, NYCEM has activated the city’s Heat Emergency Plan. This comprehensive, multi-agency effort aims to protect New Yorkers from heat-related risks. Key actions include the widespread opening of Cooling Centers across all five boroughs, enhanced outreach to the homeless population, and intensified public information campaigns. Agencies are actively monitoring health impacts in real-time and identifying at-risk individuals – such as older adults and those with chronic health conditions – through coordinated outreach and targeted alerts.

Finding relief from the heat is made easier with various city resources. Cooling centers will be open throughout the five boroughs, and their locations, including accessible and pet-friendly facilities, can be found by calling 311 or visiting the city’s Cool Options Map. This map also highlights other “Cool Options,” which are free, air-conditioned public spaces. Additionally, New Yorkers can access outdoor cooling options like spray showers and drinking fountains through Cool It! NYC, and public outdoor pools, including those in State Parks, remain open.

The New York City Department of Homeless Services (DHS) is intensifying its round-the-clock efforts to engage individuals experiencing homelessness, providing water and essentials, and encouraging them to seek shelter and cooler environments. If you see someone you believe to be experiencing homelessness and in need of assistance, please contact 311.

To safeguard your health and well-being during this heatwave, remember these vital tips: seek air-conditioned locations even for a few hours, limit strenuous outdoor activity especially between 11:00 AM and 4:00 PM, and stay hydrated by drinking water every 15 minutes, even if you don’t feel thirsty (avoid alcohol and caffeine). Dress in lightweight, light-colored clothing and check on vulnerable individuals. Never leave children or pets in a vehicle, even for a few minutes.

For those working outdoors, employers must provide water, rest, and shade. Use the buddy system to monitor for signs of heat illness in yourself and coworkers, and take regular breaks in shaded or cool areas. Immediately call 911 if you or someone you know experiences hot dry skin, trouble breathing, rapid heartbeat, confusion, disorientation, dizziness, nausea, or vomiting.

Pet owners should ensure their pets have plenty of fresh water and walk dogs during the cooler morning and evening hours, as hot asphalt can quickly burn sensitive paw pads. Be aware of signs of overheating in pets, such as excessive panting, drooling, or weakness.

To help prevent brownouts and electrical disruptions during this period of high energy demand, New Yorkers are urged to conserve energy. This includes setting air conditioners to 78°F or the highest comfortable temperature, running appliances like ovens and dishwashers in the early morning or late at night, and keeping shades, blinds, and curtains closed to block unwanted heat. Remember to turn off AC and lights when not at home, and inform your utility provider if anyone in your household depends on electricity for medical equipment.

Beyond the heat, scattered severe thunderstorms are possible Friday afternoon through Friday night, with a primary threat of damaging wind gusts. There’s also a minor risk of localized flash flooding. The city continues to monitor regional air quality, including potential impacts from Canadian wildfires. During periods of poor air quality, limit outdoor activities, consider wearing a mask, and check AirNow.gov for current readings.
