Extreme heat is one of New Jersey’s most dangerous and deadly weather-related hazards. It occurs when high temperatures and humidity persist for several days, making it harder for the body to cool itself and increasing the risk of heat-related illnesses. Older adults, infants and young children, people with chronic health conditions, outdoor workers and those without air conditioning are especially vulnerable.

Heat-related illnesses can include heat rash, sunburn, heat cramps, heat exhaustion and heat stroke. Knowing the warning signs and taking preventive measures can help keep you, your family and your community safe.

With the heat wave hitting New Jersey this holiday weekend, the NJ Office of Emergency Management (NJOEM) and the NJ Department of Health (DOH) have shared the following resources and information:

Before Extreme Heat

Take steps to prepare before temperatures rise:

• Learn the signs and symptoms of heat-related illness. Call 9-1-1 if symptoms become severe.
• Check heat alerts and forecasts from the National Weather Service or trusted weather apps. Learn the difference between heat outlooks, watches, warnings and advisories.
• Install and test air conditioners and fans before hot weather arrives.
• Make simple home improvements to keep cool air inside, such as closing blinds and curtains, using weather-stripping around doors and windows and running attic fans if available.
• Plan for potential power outages.
• Use Chill Out NJ to find places where you can stay cool anytime.
• Identify local cooling centers and other air-conditioned locations in advance.
• Reschedule outdoor activities or events when possible.
• Consider joining or organizing a neighborhood check-in system to help vulnerable residents during heat emergencies.
• Review available state and local resources that may help reduce energy costs.

During Extreme Heat

Follow these safety tips to reduce your risk of heat-related illness:

• Drink plenty of water and stay hydrated.
• Wear loose-fitting, lightweight, light-colored clothing.
• Limit strenuous outdoor activities, especially during the hottest part of the day.
• Seek shade when outdoors, wear a wide-brimmed hat and apply sunscreen regularly.
• Use air conditioning whenever possible. If air conditioning is unavailable, take cool showers or baths and seek out cooling centers or other air-conditioned locations.
• Avoid using ovens and other appliances that generate heat.
• Limit alcohol and avoid heavy, fatty, or sugary foods.
• Check on family members, neighbors, and friends, especially older adults and others at higher risk. Be a “Cool Buddy” and help ensure they are safe.
• Watch for signs of heat cramps, heat exhaustion and heat stroke.
• During heat emergencies, call or text 2-1-1 for information about official cooling centers.

Child and Pet Safety

• Never leave children, older adults, people with disabilities, or pets in a parked vehicle, even for a short time. Temperatures inside a vehicle can become dangerous within minutes.
• Avoid walking pets on hot asphalt or pavement, which can burn their paws. Walk pets during the early morning or evening when temperatures are cooler.

Cooling Centers and Resources

Local cooling centers may open during periods of extreme heat to provide a safe, air-conditioned environment. Visit the New Jersey Cooling Centers page or contact your local Office of Emergency Management to find a cooling center near you. Extreme heat can also increase the likelihood of power outages. Visit the Power Outages page for information on preparing for and responding to outages during severe weather.
