Westport Offshore Fishing

Westport is Washington State's premier offshore fishing port, located at the southern entrance to Grays Harbor on the rugged Pacific coast. The Westport Marina and the Grays Harbor jetty system provide access to the open ocean, where the continental shelf extends roughly 25 to 35 miles before dropping into deep water. This is big-water fishing — the Pacific Northwest coast is exposed to open ocean swells, strong currents, and rapidly changing conditions that demand experienced seamanship. But the rewards are significant: some of the best salmon and halibut fishing on the West Coast, a productive bottom fishery for lingcod and rockfish, and — during summer — access to the albacore tuna migration that brings these warm-water pelagics within range of the Washington coast.

Chinook salmon are the crown jewel of Westport fishing, available from May through September with peak action in July and August when fish stage on the shelf before entering the Columbia River and other coastal rivers. Coho salmon overlap from July through September. Pacific halibut fishing runs from May through September, with fish from 20 to over 100 pounds taken on the shelf at 20 to 40 fathoms. Lingcod and rockfish provide year-round bottom fishing on the reefs and pinnacles within 20 miles of the jetty. Albacore tuna arrive from late July through September, typically in the warmest water available along the outer edge of the shelf. In strong years, albacore push within 30 miles of Westport; in poor years, fish may sit 80 or more miles offshore. Dungeness crab adds a lucrative winter fishery to the port's calendar.

Westport sits at the northern end of the West Coast albacore migration corridor, and the waters here are the coldest on this list. Surface temperatures rarely exceed 60 degrees even in August, meaning albacore fishing requires finding the warmest available water along the shelf edge and beyond. On SST charts, look for the 58 to 60-degree water — albacore off Washington will feed in slightly cooler water than they tolerate off California or Oregon. The Columbia River plume, which extends south and west from the river mouth, creates a distinct fresh-water lens that influences surface temperatures and can push bait offshore. Astoria Canyon, to the south near the Oregon border, creates upwelling and current features that attract bait. For salmon and halibut, monitor temperature structure on the shelf itself — the warmest water on the shelf often concentrates bait and the salmon feeding on it.

Rigline is essential for Westport anglers chasing albacore in the cold waters of the Pacific Northwest. Our SST data shows the warmest water within range of the harbor, whether it sits 25 or 80 miles offshore, and our trend analysis reveals whether the warm-water edge is advancing or retreating. For salmon fishing, Rigline maps the subtle temperature structure on the shelf that concentrates bait and fish. Our current overlays show the Columbia River plume influence and shelf-edge currents, helping you understand why fish position where they do and how to intercept them most efficiently.
