The Park Service's Mid-Atlantic Inventory and Monitoring Network tracks ecosystem "vital signs," including weather and climate, across the Mid-Atlantic region. This summary covers 2022 at Richmond National Battlefield Park, using county-level data averaged across Caroline, Chesterfield, Hanover and Henrico counties, Virginia, from NOAA's Climate at a Glance program, with records back to 1895.

Weather is the atmosphere's short-term changes, over minutes to months; climate is the pattern expected over 30 years or more — climate is what you expect, weather is what you get.

Since 1895, both temperature and precipitation have risen in the park's counties — about +0.1°F and +0.37 inches per decade.

Park Service scientists project that by 2100, the park's annual average temperature will rise 2.7–8.5°F, from best- to worst-case scenarios, and annual precipitation will increase 8%–13% (Gonzalez and others, 2018). Rapid climate change already challenges parks, altering wildlife migrations, threatening cultural resources and facilities with more destructive storms, and disrupting habitat.
