Generally, April continues to bring winter weather to Grandfather Mountain before more spring-like conditions arrive in May.

The weather station near the Swinging Bridge reported 2.67 inches of precipitation in April 2022, while observations recorded near the park’s Nature Museum saw 2.75 inches. Precipitation is also measured at the latter location, as high winds can make it difficult to record accurate observations at the top.

The weather station near the park’s Nature Museum recorded 0.6 inches of snow April 9 and trace amounts of winter precipitation April 10, 18 and 19.
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.
