Check the National Weather Service forecast for the park. (Locations above the Fall Line, like Fort Marcy and Turkey Run Park, may be several degrees cooler.)
Winters on the parkway are generally cold, with nighttime lows frequently near freezing and occasional snowfall. Please be alert for snowplows and icy spots on roadways.
Weather during spring and fall is generally moderate, but can change quickly, especially near the Potomac River. Layers of clothing are recommended.
