Summer-like Heat Grips South Carolina with Highs in the 90s
US · Published May 18, 2026
South Carolina is experiencing unseasonably warm temperatures more typical of late June than mid-May.
According to South Carolina Public Radio, a ridge of high pressure, known as the Bermuda ridge, is driving this heat wave, with temperatures expected to reach the 90s across much of the state.
Coastal areas will see slightly cooler highs in the 80s due to the Atlantic Ocean's moderating influence.

Why It's Important?

The heat wave poses risks for residents not yet acclimated to summer-like conditions. Prolonged exposure to high temperatures can lead to dehydration, heat exhaustion, or heat stroke, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. Outdoor workers and individuals engaging in physical activities during peak heat hours are also at risk. The UV Index in the 'very high' range increases the likelihood of sunburn and other skin damage without proper protection. While the heat is not expected to break records, it serves as a reminder of the importance of heat safety measures.
