Weather, and climate
The Mid-Atlantic Inventory and Monitoring Network tracks weather and climate as one of the park's ecosystem "vital signs." Weather is what happens in the atmosphere from minutes to months — the rain or sun outside right now. Climate is what you expect from patterns over 30 years or more: climate is the hot summer you expect, weather the warm rainy day you get. The figures are county-scale data from NOAA's Climate at a Glance program, compared with the 1895–2022 averages.
Temperature
The year averaged 58.1°F, 2.5°F above normal. Nine months were warmer than usual; winter and fall stood out.

| Month | Total (in.) | Departure (in.) |
|---|---|---|
| January | 3.45 | +0.14 |
| February | 3.33 | +0.31 |
| March | 1.35 | −2.32 |
| April | 5.27 | +1.89 |

| October | 1.43 | −1.88 |
| November | 2.31 | −0.68 |
| December | 5.59 | +2.31 |
The long view
Since 1895, the county's average annual temperature has risen about 0.1°F per decade and its annual precipitation about 0.33 inches per decade. NPS scientists project that by 2100 the park's average temperature will rise 2.9–8.6°F, from the best-case to the worst-case scenario, and annual precipitation 8–14 percent.
