Geography & climate

Washington County's terrain follows the broader pattern of the Coastal Plain region. The Mountains region is defined by Blue Ridge ridgelines, cool summers, frost-prone shoulder seasons, and snow at elevation; the Piedmont is rolling hills with hot, humid summers and mild winters; and the Coastal Plain is flat, sandy, and hurricane-exposed in late summer and early fall. Within the Coastal Plain, the Inner Coastal Plain transitions gradually from the Piedmont, while the Outer (Tidewater) Coastal Plain — closest to the Atlantic — is most exposed to coastal storms and tidal flooding.

Hurricane and severe-weather climatology for North Carolina counties is published annually by the State Climate Office at NC State University.

No additional counties have been created in North Carolina since 1911, and none have been dissolved or merged. Historic county-formation records are maintained by the North Carolina Department of the Secretary of State and the State Archives.
