RALEIGH, N.C. — As North Carolinians prepare for Fourth of July celebrations, state health officials are urging residents to take extra precautions as a dangerous heat wave is expected to grip much of the state through the holiday weekend.
The North Carolina Department of Health and Human Services (NCDHHS) says daytime high temperatures are expected to exceed 100 degrees in many areas. Combined with high humidity, the heat index—or “feels like” temperature—could reach as high as 110 degrees.
Health officials are encouraging anyone spending time outdoors or in locations without air conditioning to stay hydrated, limit prolonged exposure to the heat, and be aware of the warning signs of heat-related illness.
According to NCDHHS, the state has already recorded more than 1,808 emergency department visits for heat-related illnesses between May 1 and June 28, 2026. That total is significantly higher than the average of 1,363 heat-related emergency department visits during the same period from 2021 through 2025.
“Heat-related illnesses can affect anyone, regardless of age or physical condition, so it’s important for everyone to stay alert when spending time outside over the holiday,” said Dr. Zack Moore, NCDHHS State Epidemiologist. “Recognizing the symptoms of heat illness early is key to preventing serious complications.”
Know the Signs
Health officials say recognizing the symptoms of heat-related illness can save lives.
Signs of heat exhaustion include:
- Dizziness
- Heavy sweating
- Nausea
Anyone experiencing these symptoms should move to a cool or air-conditioned area, sip cool water, and seek medical attention if symptoms do not improve.
If left untreated, heat exhaustion can progress to heat stroke, a life-threatening medical emergency.
Symptoms of heat stroke include:
- Confusion
- Slurred speech
- Loss of consciousness
If someone shows signs of heat stroke, officials advise calling 911 immediately, moving the person to a cooler location, loosening or removing excess clothing, and cooling the body with water, ice, or cold, wet towels while waiting for emergency responders.
Staying Safe
NCDHHS recommends taking the following precautions during the holiday weekend:
- Drink plenty of water, even if you don’t feel thirsty.
- Take frequent breaks in shaded or air-conditioned areas.
- Wear lightweight, light-colored clothing.
- Avoid strenuous outdoor activity during the hottest part of the day.
- Never leave children or pets unattended in parked vehicles.
- Check on older adults, young children, and neighbors who may be more vulnerable to extreme heat.
With thousands expected to gather for parades, cookouts, fireworks, and other Independence Day celebrations, health officials say a little preparation can help ensure a safe and enjoyable holiday weekend.
