A dorsal fin cuts the surface off Point Defiance, or maybe it's from a dock on the Key Peninsula, and the text goes out to everyone: the orcas are back. It's a genuine thrill, the kind that stops a dinner conversation mid-sentence. But if you've lived here long enough to remember when that sighting meant something specific, the math has quietly shifted under your feet. The whale gliding past your shoreline this August is now more likely to be a very different animal than the one your parents pointed out from the same spot thirty years ago.
Two Whales, One Word
Puget Sound residents have always used "orca" as a catchall, but there are really two distinct populations sharing these waters, and they don't behave alike, eat alike, or travel alike. The Southern Residents, organized into J, K, and L pods, eat fish, primarily Chinook salmon, and their movements track the runs. The other group, known as Bigg's or transient killer whales, hunts seals, sea lions, and other marine mammals, which lets them roam more widely and unpredictably. As one longtime West Seattle chronicler put it, the mammal-eating transient orcas behave nothing like the fish-focused residents most people picture.
The tell is often in the pacing. Southern Residents tend to be leisurely, sometimes stalling in one spot for a while as they work a school of fish. Bigg's whales move fast and cover ground, which is why volunteer trackers with the Orca Conservancy have described being caught off guard mid-chase, expecting the slower travel patterns of residents and instead watching a large group of transients blow past a ferry route in a fraction of the time they'd planned for.
What Forty-Seven Years of Sightings Actually Show
This isn't a hunch. University of Washington researchers pulled sighting reports from the Whale Museum's archive stretching from 1978 to 2022, nearly half a century of citizen observation, and modeled the migration patterns. The finding, published in a 2026 analysis, is that Southern Resident killer whales are spending less time in inland waters like Puget Sound overall, while Bigg's whales are showing up more. J pod remains a relatively steady presence, but K and L pods are visiting less often than they used to.
One of the researchers summed up what long-time observers had already suspected: the data confirms things people have been noticing on the water for years. The Southern Resident population itself is small enough that every shift matters. As of the 2026 study, roughly 74 individuals remain across all three pods, a number that has hovered in the low seventies for years and leaves little room for error in how the population is managed.
None of this means orcas are scarce around here. It means the orca boom many residents have noticed over the past several summers is disproportionately a Bigg's story, not a Southern Resident one.
Why August, Specifically
August earns its reputation as the best month for sightings for practical reasons: calmer seas, more daylight hours, and salmon runs that draw fish-eating whales toward the same channels boaters and shoreline walkers already use. But the underlying motive is worth remembering whenever a pod shows up somewhere unexpected. When more than two dozen Southern Residents made a surprise circuit around Vashon Island one September, the executive director of Sound Action watched from shore and put it simply.
They came for salmon, not the scenery.
That's true in August too. The whales aren't drawn by the view from Colvos Passage or the quiet of Minter Bay. They're following fish, and the same currents and baitfish patterns that make certain passages good salmon habitat also make them reliable places to watch from land.
Where Locals Are Actually Seeing Them This Month
Puget Sound's shape works in a resident's favor here. Whales tend to funnel through the same narrow passages rather than spreading evenly across open water, which means a handful of specific shorelines do most of the producing.
- Colvos Passage, the channel between Vashon Island and the Kitsap Peninsula, sees regular traffic from both Southern Residents and Bigg's whales moving north and south between Tacoma and central Puget Sound.
- Point Defiance Park in Tacoma, particularly the Dalco Passage overlook and Owen Beach, has produced enough sightings over the years that South Sound Talk once noted that Tacoma residents rarely think of their own waterfront as whale territory, even though dozens of sightings happen there annually.
- Point Robinson, on the northeast corner of Maury Island, sits at a natural pinch point between Vashon and the mainland where both ecotypes have been documented passing close to shore.
- Kopachuck State Park, Cutts Island, and Minter Bay, all within a short drive of Gig Harbor and the Key Peninsula, show up repeatedly in shore-based sighting reports as whales work the waters around the South Sound's quieter inlets.
- Elliott Bay, tracked closely by West Seattle Blog's ongoing coverage, has become a surprisingly consistent spot for Bigg's whales hunting close to the downtown waterfront.
Washington State Ferries crews are also a quiet but reliable part of this network. Vessel captains routinely radio in sightings from routes like the Fauntleroy-Vashon-Southworth triangle, which is part of why so many confirmed reports reference a specific ferry by name.
How to Track a Sighting Without Guessing
The organized side of this hobby is more accessible than most people realize. Orca Network runs a volunteer-driven Whale Sighting Network that collects and shares real-time reports from shore-based watchers, boaters, and ferry crews. The Center for Whale Research offers a free companion tool, the Whale Track app, with real-time updates and pod identification. The Orca Behavior Institute compiles its own monthly sightings maps covering the entire Salish Sea, useful for spotting patterns over a season rather than a single day.
For anyone on the water rather than watching from shore, distance matters. Federal guidelines require staying at least 100 yards from any orca and 200 yards from humpback whales, rules that exist because vessel noise and proximity measurably affect how whales hunt and communicate. That concern is significant enough that Quiet Sound, a Washington Maritime Blue program, has spent recent years building a mariner alert system that pings commercial vessels within 10 nautical miles of a confirmed whale, specifically because faster passenger ferries create real collision risk in these same narrow passages.
Living With the Water's Rhythms
What all of this adds up to is a small correction to a story residents have been telling themselves. The orcas passing through this August are proof that Puget Sound's waters are still doing what they've always done, feeding a population that depends on salmon and current and quiet. Knowing which whale you're actually looking at, and why it chose that particular passage on that particular afternoon, is the kind of local knowledge that turns a lucky sighting into an understanding of the place you live.
If you're already the kind of person who checks the sighting network before checking the tide chart, you already know this stretch of water better than most. At Julia Runyan, we spend as much time watching these waters as we do the market around them, and we're always glad to compare notes on where the fins were spotted this week.
