Charleston, SC – An extreme heat advisory has been issued for several counties in the Lowcountry as dangerously high temperatures are expected this weekend. Beginning Saturday morning, residents should prepare for heat index values that may soar as high as 115 degrees, contributing to increased risks for heat-related illnesses.
The counties affected by the advisory include Inland Berkeley, Coastal Colleton, Coastal Jasper, Tidal Berkeley, Dorchester, Beaufort, and Charleston. The National Weather Service (NWS) anticipates temperatures on Sunday could reach as high as 101 degrees, while 100 degrees is expected for Monday. An extreme heat watch will also be in effect from Sunday morning until Monday evening.
In light of the anticipated heat, the NWS warns that the combination of hot temperatures and high humidity can significantly increase the likelihood of heat-related conditions such as heat exhaustion and heat stroke. Residents are urged to stay hydrated by drinking plenty of water and to take frequent breaks in shaded or air-conditioned environments.
In response to the extreme temperatures, cooling centers are being opened throughout Charleston. Residents are encouraged to utilize these facilities to escape the heat. Information regarding the locations and operational hours of these cooling centers is available through local resources.
Outdoor workers are particularly vulnerable during these extreme weather conditions, and the Occupational Safety and Health Administration (OSHA) recommends that employers incorporate frequent rest breaks in shaded or air-conditioned areas. It is also critical for individuals to monitor for signs of heat-related illness in themselves and others, relocating anyone displaying symptoms to a cooler environment immediately.
As per the NWS update issued on July 25, 2025, at 7:03 PM, the heat advisory will remain effective until Sunday at 10 AM. Historically, heat poses a significant risk in the United States, being a leading factor in weather-related fatalities, with hundreds of deaths recorded annually. The most vulnerable populations include individuals without air conditioning, small children, and the elderly, making it vital to check on these groups during periods of extreme heat.
Moreover, the NWS emphasizes that it is dangerously unsafe to leave children, pets, or anyone else in vehicles during extreme temperatures, even for short periods. The potential for heat stress in enclosed spaces escalates rapidly. The NWS has also distributed resources focused on public safety and health concerning excessive heat events.
To further enhance public safety regarding heat conditions, the CodeRED emergency notification system has been launched in Bulloch County. This system will provide timely alerts for emergencies, including extreme weather conditions, to keep residents informed and safe.
