In order to better understand ecosystem health in national parks, the Eastern Rivers and Mountains Network measures ecosystem "vital signs" in select national parks in West Virginia, Pennsylvania, New Jersey, and New York. One of those vital signs is weather and climate. Below is a summary of 2021 weather conditions at Gauley River National Recreation Area.

This brief provides county-scale weather data averaged from all of the counties surrounding the park, including data from 1895–2021 (i.e. period of record). These counties include Fayette and Nicholas counties, West Virginia. Data and analyses herein are courtesy of the National Oceanic and Atmospheric Administration's (NOAA) Climate at a Glance Program.

Weather vs. Climate

First of all, what is the difference between weather and climate? Weather consists of the short-term (minutes to months) changes in the atmosphere. Weather is what is happening outside at this very moment, be it rain, snow, or just a warm sunny day. Climate is what you expect to see based on long-term patterns of over 30 years or more. An easy way to remember the difference is that climate is what you might expect, like a hot summer, and weather is what you get, like a warm rainy day.

The following information includes a discussion of 2021 weather placed in the context of long-term climate (i.e. how did 2021 compare to a "normal" year?).

2021 Summary

In all, 2021 was warmer than average and had below-normal total precipitation. The year ended as the 15th warmest and 37th driest on record. Data indicate that over the long term, annual average temperature and annual total precipitation have both increased (+0.07 °F per decade and +0.12 inches per decade, respectively).

Temperature

In total, 2021 was the 15th warmest year recorded in the counties surrounding the park, and three out of four seasons were warmer than normal (Figure 1). Seven months had higher than normal temperatures with December being almost 9 °F above the long-term average (Table 1).

Precipitation

The year 2021 was the 37th driest year recorded in Fayette and Nicholas counties, WV (Figure 2). The winter was moderately wet, but the other seasons were normal or drier than average. In total, 44.29 inches of precipitation fell, 3.9 inches less than the long-term average (Table 2).

Temperature and Precipitation Trends
(1895-2021)

Data for Fayette and Nicholas counties, West Virginia indicate that annual average temperature has increased approximately +0.07 °F per decade and annual total precipitation has increased approximately +0.12 inches per decade since 1895 (Figure 3).

National Park Service scientists have forecast future changes in climate too. Models estimate that by 2100, annual average temperature at the park will increase by 2.9–8.8 °F (from a best-case to worst-case scenario, respectively). Annual total precipitation is expected to increase by 6–11% (see Gonzalez et al., 2018 for details).

Climate Change

Today's rapid climate change challenges national parks in ways we've never seen before. Wildlife migrations are altered, increasingly destructive storms threaten cultural resources and park facilities, habitat is disrupted—the list goes on. Go to the NPS Climate Change site to discover how climate change is affecting our nation's treasures, what the National Park Service is doing about it, and how you can help.
