Houston, TX, August 20, 2026 —
HOUSTON – A Heat Advisory has been issued for the Houston area, beginning Thursday at noon and extending through Friday evening. The National Weather Service is warning residents of dangerously high temperatures and humidity levels that are expected to create hazardous conditions.
During the advisory period, the heat index, which combines temperature and humidity, is forecast to reach 108°F or higher. This level of heat poses a significant risk of heat-related illnesses, particularly for individuals who are not accustomed to the heat or those who spend prolonged periods outdoors.
Officials are urging caution and advising the public to take precautions to stay safe. This includes limiting outdoor activities during the hottest parts of the day, staying hydrated by drinking plenty of fluids, and wearing lightweight, light-colored clothing.
The outlook for the region indicates a prolonged period of intensely hot weather. Following the initial Heat Advisory, the forecast suggests a continuation of triple-digit heat, with little to no significant relief anticipated through the course of the following week. This extended period of extreme heat will likely necessitate ongoing vigilance and adherence to heat safety guidelines.
Authorities recommend checking on vulnerable individuals, such as the elderly and young children, and ensuring they have access to cool environments. It is also advised to never leave children or pets unattended in vehicles, as interior temperatures can rise to dangerous levels rapidly.
