The US West Coast runs on an entirely different engine than the East. Forget the Gulf Stream. Out here, the California Current flows south from British Columbia to Baja, carrying cold, nutrient-rich water that upwells at the continental shelf edge and fuels one of the most productive marine ecosystems on Earth. The result is a seabird spectacle measured in millions: shearwaters massing in rafts that darken the horizon, phalaropes spinning in tidal lines, Black-footed Albatrosses banking over the swells within an hour of port.
The species are different too. Where East Coast pelagics chase Pterodroma petrels and Band-rumped Storm-Petrels, the West Coast delivers alcids. Rhinoceros Auklets, Cassin’s Auklets, Common Murres, Pigeon Guillemots, and Marbled Murrelets replace the Atlantic murres and Dovekies. Mix in three species of jaeger, Sabine’s Gulls, and the possibility of a Short-tailed Albatross on a good day, and you have a pelagic portfolio that rivals anything on the continent.
Here’s what you need to know about the best departures on offer.
Washington: Westport
Westport sits at the mouth of Grays Harbor on Washington’s southern coast, and the Westport Seabirds operation has been running pelagic trips from here for decades. The location is nearly perfect: the continental shelf lies close to shore, and the upwelling off the Washington coast concentrates seabirds in numbers that can overwhelm even experienced birders.
Late summer is the prime season. From July through September, Pacific shearwaters stage off the Washington coast in staggering concentrations. Sooty Shearwaters are the core species, sometimes appearing in flocks of tens of thousands. Buller’s, Pink-footed, Flesh-footed, and Short-tailed Shearwaters join them, creating a shearwater diversity unmatched elsewhere in North America. Northern Fulmar is reliable. Pomarine and Parasitic Jaegers work the flocks constantly. Fork-tailed Storm-Petrel is the default small storm-petrel here—unusual enough to be exciting on East Coast trips, routine on a Westport departure.
Alcid diversity peaks in fall and winter. Common Murre, Pigeon Guillemot, Marbled Murrelet, Rhinoceros Auklet, and Cassin’s Auklet all occur. Tufted and Horned Puffins are possible, especially on early morning departures when they’re actively commuting between colonies and feeding grounds. Ancient Murrelet turns up on fall trips.
The rarity potential is real. Black-footed Albatross occurs throughout the season; Laysan Albatross is possible in late fall. Short-tailed Albatross—once nearly extinct, now slowly recovering—has been recorded on Westport trips multiple times. This is one of the most accessible places in North America to stand a genuine chance of seeing a Short-tailed.
Oregon: Heceta Bank
Newport, Oregon, sits at the edge of something exceptional: Heceta Bank, a shallow offshore plateau that generates some of the most intense upwelling on the West Coast. Cold, nutrient-rich water wells up continuously here, driving a food chain that terminates in seabirds. Oregon Pelagic Tours operates from Newport, reaching Heceta Bank within a few hours of departure.
The shearwater numbers in summer and fall can be extraordinary. On strong upwelling years, concentrations of Sooty Shearwaters on Heceta Bank rival anything seen at Westport, with the dense waters sometimes producing bird counts in the hundreds of thousands over the course of a day. Buller’s Shearwater is regular; Pink-footed and Short-tailed are annual in small numbers. Black-footed Albatross is a near-certainty on summer and fall trips.
Oregon adds a few species that are harder to find farther south. Horned Puffin and Ancient Murrelet are regular fall targets. Flesh-footed Shearwater, uncommon on most West Coast trips, appears more reliably off Oregon and Washington than off California. The jaeger show in September and October—Pomarine, Parasitic, and Long-tailed—is among the best anywhere on the coast.
For birders who’ve covered Westport, Oregon offers a slightly different mix with comparable intensity. The two locations together give a thorough survey of the northern California Current ecosystem.
California: San Diego and Southern Waters
Southern California’s pelagic birding occupies a different ecological zone than the Pacific Northwest. The California Current weakens as it heads south, and warm-water incursions from Baja push tropical seabirds north—especially in El Niño years, when the thermocline drops and tropical species penetrate well into California waters.
San Diego Offshore Pelagic trips, coordinated by Buena Vista Audubon and San Diego Field Ornithologists, depart Mission Bay aboard a large charter vessel into this transitional zone. The target list reads differently than a Westport trip: Least Storm-Petrel, Black Storm-Petrel, and Wedge-rumped Storm-Petrel are the specialties—small, dark storm-petrels that breed on offshore Mexican islands and range north to California in summer and fall. Black-vented Shearwater is the most abundant shearwater here, replacing the Sooty-dominated flocks of the north. Elegant Tern is a common sight inshore. Scripps’s Murrelet—a California endemic—is a priority species on early morning departures.
In strong El Niño years, the rarity potential spikes dramatically. Red-billed Tropicbird, Townsend’s Shearwater, and vagrant petrel species have all appeared off San Diego during warm-water events. Blue-footed Booby occasionally wanders north from Baja. The combination of accessible tropical specialties and the chance of genuine rarities makes San Diego a compelling destination for birders who’ve already done the northern California Current circuit.
Monterey Bay, further north, was historically the signature California pelagic location—Shearwater Journeys ran trips from Moss Landing for four decades, and the submarine canyon there concentrates seabirds year-round. That operation retired, but Monterey Bay remains one of the most seabird-rich stretches of California coastline, and new operations have occasionally offered trips into the canyon.
Alaska: Kenai Fjords
For sheer spectacle, nothing on the West Coast touches Alaska. Alaska Seabird Charters operates out of Seward in Kenai Fjords National Park, putting birders into some of the most biologically productive waters in the North Pacific.
Kenai Fjords is alcid country at a scale that’s difficult to convey. Horned and Tufted Puffins are measured in thousands. Common and Thick-billed Murres pack into colonies on exposed sea cliffs. Pigeon Guillemots, Marbled Murrelets, Kittlitz’s Murrelets, and Ancient Murrelets are all present. Pelagic, Brandt’s, and Double-crested Cormorants breed throughout the fjords. Black-legged Kittiwakes, Glaucous-winged Gulls, and Arctic Terns are constant companions.
The offshore waters add shearwaters and storm-petrels to the mix. Short-tailed Shearwater is the dominant species in fall, appearing in concentrations comparable to the peak years off Washington. Northern Fulmar is ubiquitous. Fork-tailed Storm-Petrel breeds here and is seen throughout the season. Pomarine Jaeger is regular; Long-tailed Jaeger—rare to uncommon farther south—is more reliably encountered in Alaskan waters.
The landscape alone justifies the trip. Calving glaciers, breaching humpback whales, Steller sea lions, and sea otters appear on almost every departure. The birding operates on a different scale up here, but the platform is also different: wildlife cruise boats in protected fjord waters are a more stable ride than a dedicated pelagic charter in open ocean.
Best Seasons by Region
The West Coast’s pelagic season runs roughly May through November, but peaks differ by region:
- Westport, WA: July through September for shearwater numbers; September and October for jaeger diversity and fall alcid movement. Winter trips target scoters and wintering alcids.
- Newport, OR: July through October for shearwaters and albatrosses; September for peak jaeger activity on Heceta Bank.
- San Diego, CA: Late summer and fall (August through October) for storm-petrels and tropical rarities; El Niño years amplify everything.
- Kenai Fjords, AK: May through September for breeding seabirds and accessible colonies; September for shearwater concentrations and fall alcid movement.

Tips for West Coast Pelagics
The swell is different out here. Pacific swells travel farther than Atlantic groundswells and arrive with a longer period. The motion is slower and more rolling than the sharp chop common on East Coast trips, but it affects some people more because it’s harder to anticipate. Take the same seasickness precautions you would anywhere else.
Dress for cold even in summer. The California Current is cold. Even in August, Westport and Oregon can produce temperatures in the low 50s Fahrenheit on the water, amplified by wind. Layers are not optional; a waterproof shell is essential.
Bring a longer lens. West Coast pelagics often have good albatross and shearwater activity at closer range than Atlantic trips, partly because the birds are more numerous and less wary of boats. But alcids flush easily and are often at distance. A 500mm equivalent gives you the flexibility to cover both scenarios.
Learn the murrelets. Marbled, Ancient, Scripps’s, Craveri’s, and Kittlitz’s Murrelets all occur depending on location and season, and separation is genuinely tricky at range. Reviewing the field marks before your trip pays dividends in the field.
Book Washington and Oregon trips early. Westport and Oregon Pelagic Tours trips fill quickly, especially peak-season departures. Both operations have email lists for trip announcements—sign up before the season opens if you want first access.
