Knoxville Braces for Significant Increase in Extreme Heat Days
knoxville is projected to experience a considerable rise in days with temperatures reaching 90 degrees Fahrenheit or higher, according to climate prediction data. Between 2036 and 2065, the city could see 60 to 90 such days annually, more than double the current average. This trend is consistent with the faster rate of global temperature increase, a pattern expected to persist based on climate models.
While east Tennessee is anticipated to remain slightly cooler than other regions of the state, West and Middle Tennessee could face an even more intense heat wave, with 90 to 120 days per year exceeding 90 degrees. Cities like Nashville and Memphis, which are typically hotter and more humid than Knoxville, have average July highs between 91 and 92 degrees. Knoxville’s higher altitude contributes to its slightly cooler summer temperatures compared to lower-lying areas.
The National Weather Service identifies heat as a leading weather-related cause of fatalities in the United states, with hundreds of deaths occurring each year. While heat-related illnesses can affect anyone, young children and older adults are especially vulnerable.
Experts advise that the heat index, which accounts for temperature and humidity in the shade, does not fully capture the danger of extreme heat. Direct sunlight can substantially increase temperatures, especially in the early afternoon. Urban areas with extensive pavement can also experience localized higher temperatures due to heat absorption and retention.
To stay safe during periods of excessive heat, the following precautions are recommended:
Hydration: Drink plenty of water.
Shade: Take frequent breaks in shaded areas when outdoors.
Activity Timing: Schedule outdoor work or strenuous activities for cooler parts of the day, such as early morning or late evening.
Clothing: Wear lightweight clothing.
Cooling: Utilize air conditioners and fans.
Community Care: Check on vulnerable individuals, including the elderly and those with illnesses.
Vehicle Safety: Never leave children or pets unattended in vehicles.
Stay Informed: Monitor weather forecasts for updates.
