What Half Moon Bay offers anglers
Half Moon Bay sits thirty miles south of San Francisco, where the continental shelf drops fast and cold water wells up from below. The bay itself is a working fishing town—you'll see commercial boats unloading at the dock—and the structure that makes it productive for them works for you too. Striped bass move through in spring and fall, halibut hunt the sandy bottom year-round, and rockfish hold on the reefs and kelp beds. The fog rolls in thick most mornings, but that's when the bite is often best.
The bay is split into two fishing zones by geography and access. The inner bay, closer to the harbor and the Pillar Point breakwater, holds calmer water and shallower depths—good for smaller boats and kayaks targeting halibut and perch. The outer bay and the waters beyond the breakwater see bigger swells, stronger currents, and deeper structure where the stripers and larger rockfish live. Both zones fish year-round, but timing matters for which species you'll find.
Key Takeaways
- Striped bass run through Half Moon Bay in spring (March through May) and fall (September through November), with the best fishing on incoming tides and around the Pillar Point breakwater.
- Halibut are present all year in the sandy flats of the inner bay, but bite most consistently from May through October when water temperatures warm.
- Rockfish and lingcod hold on reefs and kelp beds in the outer bay and require heavier tackle and knowledge of which rocks hold fish at different depths.
- Half Moon Bay Harbor has public boat launch facilities, and several charter operations run daily trips if you don't own a boat.
- Fog, wind, and strong currents are normal—check conditions before you leave the dock, and tell someone on shore where you're headed.
Striped bass timing and location
Striped bass enter Half Moon Bay twice a year following the same migration pattern they use up and down the California coast. Spring run peaks in April and May, when fish move north after wintering in San Francisco Bay and the Delta. Fall run begins in August and runs through November as fish move south again. Both runs concentrate around the Pillar Point breakwater and the rocky points on the north side of the bay, where current and structure funnel the fish into predictable lanes.
Incoming tide is the key to stripers here. The rising water pushes baitfish against the rocks and structure, and the stripers follow. Fish the two hours before high tide and the first hour after for the most consistent action. Early morning fog doesn't hurt—stripers bite better in low light. Live mackerel or anchovies work if you can get them from the bait shop near the harbor, but many anglers throw large swimbaits or topwater plugs and cover more water that way. The breakwater itself is accessible by foot if you want to cast from shore, though the rocks are slick and the surge can be strong.
Halibut in the sandy flats
Halibut live on the sand and mud bottom of the inner bay year-round, but they're most active and most catchable from May through October. They hunt by lying still and ambushing baitfish that pass overhead, so your presentation matters more than your location—you can catch them almost anywhere in the bay if you're in the right depth and using the right bait. The productive zone runs from about eight feet deep near the harbor out to twenty-five feet, roughly a mile offshore.
Live mackerel or squid fished on the bottom with a sliding sinker rig is the standard approach. Drop your bait, keep light contact with the bottom, and wait. Halibut bites are often subtle—a tap or a slow pull rather than a hard strike. Set the hook on anything that feels different. Drifting is more productive than anchoring because you cover more bottom and find where the fish are concentrated that day. Slack tide is often better than strong current, when the bait sits naturally instead of being swept away.
Rockfish and lingcod on the reefs
The outer bay and the waters beyond Pillar Point hold rocky reefs and kelp beds where rockfish and lingcod live. This is deeper, rougher water—you need a boat that can handle swells and a skipper who knows the marks. Depths range from thirty to eighty feet depending on which reef you're fishing. The fish are there year-round, but spring and fall see the most consistent fishing when water clarity improves and baitfish concentrate.
Vertical jigging with metal jigs or live mackerel is the primary method. Drop to the bottom, work the jig with sharp upstrokes, and hold on—rockfish bite hard and fast. Lingcod are larger and more aggressive; they'll chase a jig or eat a live bait meant for halibut. The challenge is knowing which reefs hold fish and which are picked over. Charter boats have GPS marks and current knowledge built up over years. If you're running your own boat, start with the well-known spots like the Whistle Buoy area or the reefs south of the breakwater, and talk to other anglers at the dock about what's working.
Boat access and charter options
Half Moon Bay Harbor has a public launch ramp on the east side near the bait shop and fuel dock. The ramp is concrete, well-maintained, and open during daylight hours. Parking is available but fills on weekends and good-weather days. Launch fees are modest—check with the harbormaster's office for current rates. The harbor itself is protected and easy to navigate, but the entrance can get rough in big swells, so check the bar conditions before you commit.
If you don't own a boat or prefer not to launch in unfamiliar water, several charter operations run daily trips from Half Moon Bay Harbor. Most target halibut and rockfish, with some offering striped bass trips during the spring and fall runs. Charters typically run six to eight hours, provide tackle and bait, and include a skipper who knows the marks. Reservations are necessary, especially on weekends. Call ahead or check the harbor's website for current operators and phone numbers.
Tackle and bait for Half Moon Bay
Halibut and stripers call for medium-weight spinning or conventional tackle—a six to seven-foot rod with a reel that holds at least 200 yards of fifteen to twenty-pound line. Rockfish and lingcod need heavier gear: a shorter, stiffer rod and twenty to thirty-pound line to handle the depth and the structure. Bring multiple rigs because you'll snag bottom or kelp, especially when you're learning the reefs.
Live mackerel is the most versatile bait and works for all three species. The bait shop at Half Moon Bay Harbor sells fresh mackerel, squid, and anchovies daily. If you want to fish artificially, large swimbaits (four to six inches) and topwater plugs work for stripers, metal jigs (one to four ounces depending on depth) work for rockfish, and live mackerel under a float works for halibut in shallow water. Bring more tackle than you think you'll need—Half Moon Bay's rocks and kelp are unforgiving.
Weather, safety, and timing your trip
Half Moon Bay is exposed to the Pacific, and conditions change fast. Fog is common, especially in summer and early morning, and it can roll in thick enough to reduce visibility to a few boat lengths. Wind typically picks up in the afternoon, making the outer bay rough by midday. Check the marine forecast the night before and plan to leave the harbor at first light. Afternoon trips are possible in summer when the wind is lighter, but spring and fall often mean morning-only windows.
Bring a radio, a GPS, and a compass if you're running your own boat. Tell someone on shore where you're headed and when you expect to return. Wear a life jacket—the water is cold year-round, and the current can be strong. If you're new to the area, fish with a charter first or go with someone who knows the marks. The halibut and stripers will still be there once you understand how the bay works.
Frequently Asked Questions
What's the best month to fish Half Moon Bay?
April and May for striped bass, May through September for halibut, and March through May or September through November for a mix of species. Summer fog can make morning trips difficult, so spring and fall often offer the best combination of calm weather and active fish.
Can I fish from shore at Half Moon Bay?
Yes, the Pillar Point breakwater is accessible by foot and holds striped bass during the spring and fall runs. The rocks are slick and the surge can be strong, so wear good boots and watch the swell. Halibut and rockfish require a boat.
Do I need a California fishing license?
Yes, anyone sixteen and older fishing in California saltwater needs a valid license. You can buy one online through the California Department of Fish and Wildlife website or at the bait shop in Half Moon Bay Harbor.
How far offshore do I need to go to find fish?
Halibut are catchable within a mile of the harbor in eight to twenty-five feet of water. Stripers concentrate around the breakwater and points. Rockfish and lingcod live on reefs two to five miles out in thirty to eighty feet of water.
What should I do if the fog gets too thick to navigate?
Head back to the harbor immediately. Use your GPS and radio to stay oriented, and go slow. Fog can roll in fast, and visibility can drop to near zero. It's not worth the risk—the fish will be there on the next clear day.
