How Elevation Shapes Weather
Weather Changes with Altitude
When you head to Great Smoky Mountains National Park, the weather’s got a mind of its own, thanks to the park’s varying elevations. From a low of about 875 feet (267 meters) to a high of 6,643 feet (2,025 meters), the climate shifts as you climb.
| Elevation | Temperature Range (°F) | Average Annual Rainfall (inches) |
|---|---|---|
| Low Elevations (875 feet) | 50-80 | 50 |
| Mid Elevations (3,000 feet) | 40-70 | 60 |
| High Elevations (6,643 feet) | 30-60 | 85 |
Down low, expect warmer temps and less rain. As you go up, it cools off and gets wetter. Up top, it’s chillier and snowier in winter. So, pack smart and be ready for anything. For a closer look at the park’s layout, check out the Great Smoky Mountains National Park map.
Man-Made Weather Woes
Humans have left their mark on the weather in Great Smoky Mountains National Park. Since 1948, visibility in the southern Appalachians has tanked down 40% in winter and a whopping 80% in summer, all thanks to pollution. What used to be a clear 93-mile view is now often just 25 miles, sometimes dropping to less than a mile during heavy haze.
Blame it on power plants, cars, and factories. Sulfate levels shot up by 27% from 1984-1999, mainly from power plants, making the air hazier.
Ozone pollution is another headache. Ozone levels over the park’s ridges are double what you’d find in nearby cities like Knoxville and Atlanta. This pollution comes from power plants, cars, and factories outside the park. High ozone levels can mess with your lungs and harm the park’s trees and plants.
