Beaufort County, S.C. – As late July temperatures soar, this weekend is expected to bring extreme heat to Beaufort County, with temperatures climbing into the dangerous 100-degree range. Saturday’s highs will stay in the low 90s, but Sunday and Monday will push temperatures past the 100-degree mark, with some areas reaching as high as 110°F.
Heat Index: What It Really Feels Like
While actual air temperatures are high, the heat index – which factors in both humidity and temperature – will make it feel even hotter. Starting Friday, the heat index will climb into triple digits for much of the Lowcountry, continuing throughout the weekend. According to the National Weather Service, this will create an especially dangerous heat wave, with heat index values upwards of 103°F, putting people at risk of heat cramps, exhaustion, and heat stroke, particularly during physical activity or prolonged exposure to the heat.
Why Humidity Makes It Feel Worse
Humidity plays a crucial role in how hot it actually feels. The body cools itself by sweating, but in high humidity, the evaporation of sweat slows down, making it harder for the body to regulate its temperature. As a result, people may feel much warmer than the actual temperature, increasing the risk of heat-related illnesses.
Dangerous Heat Expected Through Wednesday
The National Weather Service has labeled this a “dangerous heat wave,” with the worst conditions expected from Saturday through Monday. Savannah will see triple-digit temperatures starting Friday, while Beaufort is expected to reach 100°F by the weekend. Monday will be the hottest day, with Beaufort hitting 110°F and Savannah reaching 114°F. Though temperatures will drop slightly after Monday, they are still expected to remain in the triple digits through Wednesday.
Lack of Cooling Shelters in Beaufort County
Hannah Nichols, the Public Information Officer for Beaufort County, confirmed that there are no designated cooling shelters in the area. Residents are urged to take precautions to stay cool, including staying indoors during the hottest parts of the day, staying hydrated, and limiting strenuous activities.
Boating Forecast: Dangerous Heat on the Water
For those considering spending time on the water, the boating forecast shows that the heat risk remains high. Winds will be light, with a western breeze at 5-10 knots, shifting to a southwestern flow by the afternoon. Ocean temperatures will be in the mid-80s, with seas calm at 1-2 feet. Despite the relatively mild conditions on the water, the heat risk remains the same as being on the beach. The combination of hot air and water temperatures makes outdoor activities potentially hazardous.
