The complete county distribution, spread across 10 Washington counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Washington’s 222 northern elephant seal records belong to salt water: Skagit County leads the list, with Jefferson, Clallam, and Grays Harbor close behind, and the tightest cluster of reports sits around the San Juan Islands National Monument and Deception Pass. This is the northern reach of a species whose real strongholds lie far to the south.

Breeds in California, rests in Washington

Northern elephant seals breed on islands and beaches off California and Baja California, then disperse north to feed in the deep waters of the North Pacific. Washington sees them mostly as single animals hauled out on beaches and rocky shores, resting between long feeding dives or shedding their coat during the annual molt. The San Juan Islands are a favored place for exactly that kind of stopover.

A spring and summer visitor

Washington records climb from March through July and thin to almost nothing by December. That rhythm fits the animal’s year: elephant seals gather on their southern rookeries to breed in winter, then spread north through spring and summer, when a molting seal sprawled on a Washington beach is at its most conspicuous.

Status in Washington

This species carries no NatureServe state rank in Washington, but it is treated as native to its mapped range here, and USGS NAS does not list it as nonindigenous. It is not specifically listed under the state’s conservation framework, and the IUCN lists it globally as Least Concern.
