June 2022 saw average weather – and a fairly low amount of rain – on Grandfather Mountain, according to data recorded at the park’s official weather reporting stations.
The average high temperature for June 2022 was 66.7°, with an average low of 55.1° and a mean of 60.2°.
The warmest temperature recorded last month was 77.7° on June 13, just under 5 degrees shy of the mountain’s record June high of 82°, observed June 1, 2011, and June 9, 2008. Generally, June sees spring-like weather conditions continue on Grandfather Mountain, with slightly warmer, summertime temperatures starting to arrive.
June 19 saw the coldest temperature recorded last month with 45.5°. The lowest temperature ever observed on Grandfather Mountain in the month of June (not counting wind chill) was 31° on June 1, 1966, and June 3, 1956.
On June 17, the weather station on the Mile High Swinging Bridge recorded a wind gust of 79.1 mph, along with a sustained wind speed of 69.5 mph. The station noted two days in June with wind gusts higher than 60 mph. The highest gust ever recorded on Grandfather Mountain was 124 mph, observed Feb. 25, 2019.
The weather station near the Swinging Bridge reported 1.41 inches of precipitation in June 2022, marking the fourth driest June on record in terms of total rainfall. Observations recorded near the park’s Wilson Center for Nature Discovery saw 1.58 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 June was recorded in 2019, when 15.94 inches were observed near the bridge. The driest June on record was observed in 1986, when 0.60 inches were recorded.
The park counted 12 total days of precipitation for June 2022. The rainiest day last month was June 14, when 0.45 inches were recorded at the top. The rainiest day on record for June was June 8, 1968, when the weather station observed 4.46 inches.
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).
