The official National Weather Service Reporting Station located atop the Mile High Swinging Bridge has been providing daily weather observations since August of 1955. Gauges collect data for the National Weather Service regional office in Asheville. A monthly record of that information is filed each month with the Department of Commerce. Monitors with current weather readings are accessible to the public in the Top Shop Visitor Center and at the Nature Museum.

With rare exceptions, the temperature will be 10 to 20 degrees cooler at Grandfather Mountain than in the flatlands below. The average rate is 2.2 degrees per 1,000 feet, meaning that for each thousand feet gained, the air is 2.2 degrees cooler.
