Charleston's heat index climbed into dangerous triple digits last week, prompting safety changes that affected tourists, businesses and outdoor attractions.
One of South Carolina’s most popular summer destinations, Charleston, is known for amazing outdoor activities such as historic walking tours, horse-drawn carriage rides and waterfront attractions. But last week changed what sightseeing and outdoor activities looked like.
An Extreme Heat Warning remained in effect for Charleston and surrounding areas through the evening of July 10 after the National Weather Service forecasted the heat index values between 116 and 121 degrees. The warning covered Charleston and coastal Berkeley counties, where hot temperatures combined with tropical humidity created dangerous conditions for prolonged outdoor activities.
Visitors who would normally spend hours outside instead sought air-conditioned restaurants, museums and shops while limiting sightseeing during the hottest part of the day. Businesses also adjusted schedules to reduce the risk of heat-related illness.
The extreme temperatures also affected Charleston's animals. Horse-drawn carriage tours, one of the city's signature attractions, suspended operations beginning at 12:30 p.m. to protect horses from heat stress.
Officials continue to recommend drinking plenty of water, taking frequent breaks in air-conditioned spaces, wearing lightweight clothing and avoiding strenuous outdoor activities. Visitors should also watch for signs of heat-related illness and never leave children or pets in parked vehicles.
