The weather station near the Swinging Bridge reported 4.47 inches of precipitation in July 2022. Observations recorded near the park’s Wilson Center for Nature Discovery saw 4.82 inches. Precipitation is also measured at the latter location, as high winds can make it difficult to record accurate observations at the top.
The mountain’s rainiest July was recorded in 2013, when 23.91 inches were observed near the bridge. The driest July on record was observed in 1977, when 1.74 inches were recorded.

The Grandfather Mountain Stewardship Foundation records and reports data in two different ways:
- The park maintains an automated weather station at the top of the Mile High Swinging Bridge. The N.C. State Climate Office assists the foundation in calibrating the machines and ensuring overall accuracy of data.
- Grandfather Mountain has been an active member of the National Oceanic and Atmospheric Administration’s (NOAA) Cooperative Observer Program since 1955 by reporting weather data from locations near the Mile High Swinging Bridge and the Nature Museum (now the Wilson Center for Nature Discovery).
