SOUTH CAROLINA – The heat is cranking up again across the South Carolina Lowcountry, and inland Berkeley County is under a Heat Advisory from 11 a.m. to 7 p.m. Thursday as dangerous heat and humidity settle into the area. The National Weather Service expects afternoon temperatures to reach the mid- to upper 90s, with heat index values soaring to 112 degrees, creating conditions that can quickly lead to heat-related illnesses.
The steamy weather isn’t going anywhere just yet. Friday is expected to bring another hot day with a high near 98 degrees and heat index values as high as 106 degrees before scattered afternoon thunderstorms develop.
Temperatures will climb to around 99 degrees Saturday, with another chance for afternoon storms, before a better chance of showers and thunderstorms arrives Sunday and nudges highs down into the lower 90s. Even with the rain, it’ll still feel hot and humid across Berkeley County.
The extreme heat isn’t just uncomfortable—it can be deadly.

Earlier this summer, Berkeley County recorded its first heat-related death of 2026, underscoring how quickly prolonged exposure to high temperatures can become life-threatening.
The National Weather Service says young children, older adults, pregnant women and people with chronic health conditions are especially vulnerable to heat-related illness. Officials also remind residents never to leave children, pets or disabled adults inside a vehicle, even for a few minutes. A parked vehicle can become deadly in as little as 10 minutes.
Whether you’re heading to the lake, working outdoors, grilling out or simply trying to survive another sweltering afternoon, these products can help you stay safer and more comfortable.
1. Cooling Towels
A cooling towel is one of the easiest and most affordable ways to lower your body temperature. Simply soak it in water, wring it out and drape it around your neck. The evaporative cooling effect can provide relief while mowing the lawn, attending ball games or watching fireworks.
2. Rechargeable Neck Fans
Hands-free neck fans have become increasingly popular in South Carolina’s summer heat. They continuously circulate air around your face and neck, making outdoor festivals, youth sports and yard work much more bearable.
3. Insulated Stainless Steel Water Bottles
Hydration is one of the most important defenses against heat illness. An insulated stainless steel bottle helps keep water cold for hours—even when left in a hot vehicle or sitting in the sun during a day at Lake Moultrie or the beach.
4. Portable Misting Fans
For outdoor gatherings, camping trips or youth sporting events, a rechargeable misting fan combines cool airflow with a fine mist to lower skin temperature quickly.
5. Cooling Vests
If you spend long hours working outdoors or attending all-day events, evaporative cooling vests can help regulate your body temperature by keeping your core cooler.
6. UPF 50+ Wide-Brim Sun Hats
A wide-brim hat provides shade for your face, ears and neck—areas commonly missed with sunscreen. Look for hats with UPF 50+ protection and breathable fabrics.
7. Electrolyte Drink Mixes
When you’re sweating heavily, water alone isn’t always enough. Electrolyte packets can help replace sodium and other minerals lost during prolonged time outside.
8. Portable Personal Air Coolers
If you’re working in a garage, workshop or covered porch, a compact evaporative cooler can make small spaces noticeably more comfortable.
9. Cooling Seat Cushions
Whether you’re commuting, driving a tractor or spending hours at the ballfield, cooling gel seat cushions can reduce heat buildup and improve comfort.
10. SPF 50 Sunscreen
Preventing sunburn also helps your body regulate its temperature more effectively. Dermatologists recommend broad-spectrum sunscreen with SPF 30 or higher, especially during prolonged outdoor activities.
Heat Safety Tips
Before heading outdoors this holiday weekend, remember these heat safety tips:
- Drink plenty of water throughout the day, even if you don’t feel thirsty.
