South Heat Wave to Break Records with Triple-Digit Temperatures
US · Published Aug 21, 2026
A persistent heat wave is gripping the southern United States, with temperatures soaring into the triple digits in states like Texas and Oklahoma.
According to The Weather Company (2026-08-20), a heat dome is causing extreme heat and humidity, pushing heat indices above 105°F (40.5°C) and even 110°F (43.3°C) in areas such as southern Georgia, coastal South Carolina, the Florida Panhandle, and the mid-South region around Memphis.

Impact & Risks

The ongoing heat wave poses significant risks, particularly in the Southern Plains and Southeast Coast, where daily record highs are expected. The combination of extreme heat and high humidity is especially dangerous for vulnerable populations, including the elderly, individuals with chronic illnesses, and those without access to air conditioning. Urban areas are at heightened risk due to the heat island effect, which can exacerbate nighttime temperatures. Prolonged exposure to these conditions increases the likelihood of heat-related illnesses such as heat exhaustion and heat stroke. Residents are urged to take precautions to stay safe during this period of extreme weather.
