CHARLESTON, S.C. – The Lowcountry is about to face one of the hottest stretches of the summer, with forecasters warning of dangerous heat from Saturday through the middle of next week. With temperatures nearing 100°F and heat index values soaring up to 115°F, residents are being urged to stay cool, stay hydrated, and stay safe.
Record-Breaking Temperatures Expected
According to Storm Team 2 Meteorologist Brant Beckman, the heat is about to ramp up quickly.
“We are heading into the hottest part of the summer, with temps potentially reaching 100 degrees on Sunday. If we hit 100, it will set a new daily record,” Beckman said.
Here’s what to expect over the next few days:
Friday: Highs in the mid-90s, with a heat advisory from 11 a.m. to 8 p.m. for Georgetown and Williamsburg counties.
Saturday: Temperatures rise to the upper 90s.
Sunday: Forecasts show highs reaching 100°F, with heat index levels potentially as high as 115°F.
Why It’s So Hot: The Heat Dome Effect
A heat dome of high pressure is settling over the Southeast, pushing temperatures upward while also limiting rainfall.
“With this dome in place, the risk of rain is low for the weekend,” Beckman explained. “If we do get isolated thunderstorms, they’ll likely be fueled by intense heat and moisture. Expect heavy rainfall, lightning, and possibly strong winds if storms form.”
Heat Safety Tips
As temperatures climb, here are a few important heat safety guidelines to follow:
Drink plenty of water—don’t wait until you’re thirsty.
Avoid outdoor activity during peak heat hours (typically 11 a.m. to 4 p.m.).
Apply sunscreen every two hours and wear light, loose-fitting clothing.
Never leave children or pets in a parked car.
Take frequent breaks if working or exercising outdoors.
Extreme heat can lead to heat exhaustion or even heatstroke, which can be life-threatening. Symptoms include nausea, dizziness, headache, excessive sweating, and confusion. Seek immediate medical attention if any of these signs appear.
Stay Informed and Be Prepared
As heat-related advisories are likely to expand in the coming days, residents are encouraged to download the Storm Team 2 weather app to keep up with real-time updates on temperature, heat index, and severe weather alerts.
With low rain chances, the focus remains on protecting yourself and loved ones from the heat. Local officials may open cooling centers if temperatures continue to rise, so keep an eye on local announcements and social media alerts.
As Charleston and surrounding counties prepare for record-breaking heat, staying alert and making smart choices will be key to getting through this hot spell safely. From limiting time in the sun to staying hydrated and checking on vulnerable neighbors, small steps can make a big difference.
