LINVILLE, N.C. – July 2025 tied a record for the number of days of precipitation on Grandfather Mountain, according to data recorded at the park’s official weather reporting stations.
There were 26 days of at least trace amounts of recorded liquid precipitation (rain and the liquid equivalent of frozen precipitation, when applicable) for July 2025, tying the record originally set in 1982.
The weather station near the Swinging Bridge reported 6.37 inches of precipitation in July 2025. Precipitation at the top of the mountain includes rain and the liquid equivalent of any frozen precipitation (when applicable).
Observations recorded near the park’s Wilson Center for Nature Discovery totaled 7.64 inches of precipitation for the month. 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 day last month with the highest amount of this precipitation observed was July 13, when 0.99 inches were recorded at the top. The day with the highest amount of precipitation observed on record for July was July 4, 1989, when the weather station observed 6.25 inches.
The average high temperature for July 2025 was 69.5 degrees Fahrenheit, with an average low of 60.63 degrees and a mean of 65.07 degrees.
The warmest temperature recorded last month was 72.9 degrees on July 29, more than ten degrees shy of the mountain’s record July high of 83.2 degrees, observed July 1, 2012 (which is also the highest temperature ever recorded at the park). Generally, July sees summertime weather conditions on Grandfather Mountain, with slightly warmer temperatures having arrived.
July 6 saw the coldest temperature recorded last month with 55.6 degrees. The lowest temperature ever observed on Grandfather Mountain in the month of July (not counting wind chill) was 41 degrees on July 27, 1962.
The weather station on the Mile High Swinging Bridge noted zero days in July with a wind gust higher than 60 mph. The highest gust ever recorded on Grandfather Mountain was 124 mph, observed Feb. 25, 2019.
Weather Reporting
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).
