What to expect fishing Half Moon Bay

Half Moon Bay is a small community on the western shore of Puget Sound in Pacific County, Washington, roughly 20 miles southwest of Olympia. The bay itself is a shallow, protected inlet that opens to deeper sound water, making it accessible to both small private boats and charter operations. The primary species here are Chinook salmon (particularly in summer and fall), coho salmon, halibut, and various rockfish. The bay's proximity to deeper channels and its seasonal current patterns make it a reliable location when conditions align, though success depends heavily on the time of year and recent weather.

Access is straightforward: a public boat launch sits at the Half Moon Bay Marina, which also rents moorage and has fuel, tackle, and basic supplies. The launch fee is typically $10 to $15 per day, though prices vary seasonally. Most anglers fish from private boats or charter vessels rather than from shore, as the bay's productive water lies 200 yards to a half-mile offshore.

Key Takeaways

  • Half Moon Bay's primary fishery is Chinook salmon in summer and fall, with coho and halibut available in different seasons, all requiring saltwater fishing licenses and current Puget Sound endorsements.
  • The Half Moon Bay Marina provides the only public boat launch in the immediate area, with daily launch fees and moorage available year-round.
  • Chinook season typically runs June through September, with peak fishing in July and August when fish move through the sound's main channels near the bay.
  • Halibut fishing is best April through June and again in September and October, with fish holding in deeper water outside the bay proper.
  • Washington's saltwater regulations change annually and vary by species and area, so checking the current Puget Sound rules before each trip is essential.

Chinook salmon: summer and fall runs

Chinook salmon are the primary draw at Half Moon Bay, particularly from mid-June through September. Fish move through Puget Sound on their way to spawning rivers, and the bay's location on the main migration corridor means consistent opportunity during peak weeks. July and August are typically the strongest months, with fish ranging from 20 to 50 pounds, though larger individuals are possible.

Most anglers troll in 40 to 80 feet of water just outside the bay's mouth, using herring, anchovies, or spoons. The incoming tide and early morning hours (first two hours after sunrise) produce the most consistent bites. Boat control is critical—a slow, steady troll at 2 to 3 knots works better than faster presentations. Many charter boats operate from Half Moon Bay during this season and can put you on fish if you lack your own vessel.

Chinook regulations in Puget Sound change year to year. In recent seasons, daily limits have ranged from one to two fish, with minimum size requirements of 24 inches. Check the Washington Department of Fish and Wildlife (WDFW) Puget Sound rules before your trip, as closures and slot limits can shift based on run strength and conservation needs.

Halibut in spring and fall

Pacific halibut move into Puget Sound seasonally, and Half Moon Bay sits within a productive halibut zone. The spring bite (April through June) and fall bite (September through October) are the most reliable windows. Fish hold in deeper water—typically 100 to 200 feet—just beyond the bay's shallow interior, so you will need a boat capable of reaching those depths and equipped with a depth finder.

Halibut respond well to live herring or squid jigged on the bottom, or to heavy spoons worked vertically. Slack tide is often the most productive time, as fish feed more actively when current is minimal. A 20- to 40-pound halibut is common; larger fish are possible but less frequent. Halibut regulations in Washington include a daily limit (typically one fish per day, though this varies) and a minimum size of 32 inches. Retention of halibut is also subject to an annual quota system managed by WDFW, so confirm the current season status before heading out.

Rockfish and bottom species

Rockfish—including black rockfish, yellowtail rockfish, and quillback rockfish—are abundant in Half Moon Bay year-round and offer consistent action when salmon and halibut are slow. These fish hold around rocky outcrops and kelp beds in 30 to 60 feet of water. They are aggressive feeders and respond quickly to small jigs, spoons, or live bait.

Rockfish are a good option for anglers with smaller boats or less experience, as they do not require the precision or patience that halibut and Chinook demand. Daily limits and size restrictions apply and vary by species; black rockfish, for example, have had daily limits of 15 fish in recent years, though regulations shift. Check current WDFW rules for the specific species you intend to target.

Seasons and timing

Half Moon Bay's fishing calendar is driven by salmon migration and halibut movement. June through September is peak season overall, with Chinook salmon the main target. April through June and September through October offer halibut opportunity. Winter (November through March) sees fewer anglers and reduced Chinook presence, though coho salmon can be present in fall and early winter, and rockfish remain available year-round.

Tidal current and weather have outsized influence on daily success. Incoming tides and slack water periods typically produce better fishing than strong outgoing tides. Wind and rain are common in fall and winter; summer offers more stable conditions but also more boat traffic. Plan your trip around a favorable tide window and check the marine forecast before launching.

Regulations and licensing

All anglers fishing saltwater in Washington must hold a current saltwater fishing license and a Puget Sound Salmon and Halibut Endorsement. Licenses are available online through the WDFW website, at the Half Moon Bay Marina, or at sporting goods retailers throughout the region. A three-day license costs less than an annual license and is a reasonable option for visiting anglers.

Regulations for Chinook, coho, halibut, and rockfish change annually and sometimes mid-season based on run forecasts and conservation status. The WDFW publishes detailed rules in its Puget Sound Sport Fishing Guide, available free online and at tackle shops. Slot limits, minimum sizes, daily limits, and seasonal closures all apply. Ignorance of current rules is not a defense, so review the guide before your first cast.

Access and facilities

The Half Moon Bay Marina is the primary access point. The public boat launch operates year-round, with a daily fee of approximately $10 to $15. The marina also offers moorage by the night or month, fuel, and a small tackle shop. Restrooms and a covered waiting area are available. The marina is located on Bay Road, accessible from Highway 101.

Nearby towns—Manzanita to the north and Shelton to the south—have lodging, restaurants, and additional tackle shops. Half Moon Bay itself has limited services, so plan accordingly. Cell service can be spotty on the water, so inform someone of your intended return time before launching.

Frequently Asked Questions

Do I need a charter boat to fish Half Moon Bay?

No. A private boat of any size that can safely reach the bay's fishing grounds will work. Many anglers use 16- to 20-foot center-console or open boats. Charters are available if you lack your own vessel or prefer guided service, and they handle navigation and often provide tackle and bait.

What is the best time of year to fish here?

July and August are peak for Chinook salmon. April through June and September through October are best for halibut. Rockfish are available year-round. Summer offers the most stable weather and longest daylight, while fall can be productive but windier.

Can I fish from shore at Half Moon Bay?

Shore access is limited and unproductive. Most fish hold in deeper water beyond the bay's shallow interior. A boat is necessary to reach the productive zones. The marina and nearby beaches offer limited casting opportunity but are not the primary fishery.

What size fish should I expect?

Chinook salmon typically range 20 to 50 pounds. Halibut average 20 to 40 pounds. Rockfish are smaller, usually 1 to 3 pounds. Larger fish are possible but less common. Actual size depends on the run strength and time of year.

How far offshore do I need to go?

Chinook and coho are often found 200 yards to a half-mile from shore. Halibut require deeper water, typically 100 to 200 feet offshore. Rockfish can be found closer in, around 30 to 60 feet of water near structure. A depth finder is helpful for locating productive zones.
