What Seaside Lagoon offers anglers

Seaside Lagoon is a shallow, enclosed saltwater body in Redondo Beach that holds halibut, corbina, and leopard sharks in the warmer months. The lagoon sits behind the Seaside Lagoon public beach facility and connects to the ocean through a tidal channel, so the water quality and fish presence shift with tides and seasons. It's a protected spot that works well when the open coast is rough, and it draws both beginners and experienced anglers because the fish are close to shore and the setting is manageable.

The lagoon runs roughly 1,200 feet long and averages 8 to 12 feet deep in the center, shallower along the edges. Summer and early fall are the strongest seasons—water temperatures climb into the 60s and 70s, and halibut move in to hunt. Corbina show up in spring and again in fall. Leopard sharks are present year-round but most abundant in summer. Winter fishing is slower; the water cools and many species move offshore.

Key Takeaways

  • Seaside Lagoon holds halibut, corbina, and leopard sharks, with summer and early fall offering the best fishing.
  • Access is through the Seaside Lagoon public beach facility, which charges a day-use fee and has parking, restrooms, and a snack bar.
  • Fish the deeper channel areas and drop-offs along the edges where halibut hunt; corbina prefer the shallows and sandy bottom.
  • Bring live anchovies or small mullet for halibut, and sand crabs or small live baitfish for corbina.
  • Tides matter—incoming and slack tides often produce better than outgoing water, especially in summer.

Access and facilities at Seaside Lagoon

Seaside Lagoon is a public beach facility operated by the City of Redondo Beach. Day-use entry costs around $10 to $15 per vehicle (prices vary by season), and the lot fills quickly on warm weekends. Arrive early or visit on weekday mornings to secure parking. The facility has restrooms, showers, a snack bar, and a small sandy beach area, so it works well for families or anglers who want a full day out.

Fishing is allowed from the beach and from the water if you have a kayak or small boat. Most anglers fish from shore along the edges and in the shallow areas. The facility does not rent fishing equipment, so bring your own rod, reel, and tackle. A California fishing license is required for anyone 16 and older; you can purchase one online through the California Department of Fish and Wildlife or at most tackle shops in the area.

Best techniques and bait for halibut and corbina

Halibut are the primary target in Seaside Lagoon, especially mid-June through September. They hunt in the deeper channel and along the drop-offs where the bottom transitions from sand to deeper water. Fish live anchovies or small mullet on a light sinker rig, keeping your bait near the bottom. Cast toward the channel edges and let the bait sit; halibut often strike hard and fast. Early morning and late afternoon produce better than midday, and incoming or slack tides usually outfish outgoing water.

Corbina arrive in spring and return in fall, and they prefer the shallows and sandy flats. Use sand crabs, small live anchovies, or fresh shrimp. Cast close to shore and work the bait slowly along the bottom. Corbina are line-shy, so use light tackle and a longer leader. They feed in the early morning and again in the late afternoon, and they often bite better on overcast days or when the water is slightly turbid.

Leopard sharks are present year-round and bite readily on cut mackerel, squid, or live anchovies. They are not a trophy fish, but they are fun to catch and good practice for beginners. Fish the deeper areas and expect bites throughout the day, though dawn and dusk are usually more active.

Tides, seasons, and timing

Tides control the lagoon's fishing rhythm. Incoming tides push fresh water and baitfish into the lagoon, triggering feeding activity. Slack tide—the brief period between incoming and outgoing—often produces excellent fishing because fish are less cautious. Outgoing tides can be slow, especially in summer when the water drains and becomes stagnant. Check tide tables before you go; the NOAA tide station for Los Angeles Harbor gives accurate predictions for Redondo Beach.

Summer (June through September) is peak season. Water temperatures reach 65 to 75 degrees, halibut are active, and the facility is open daily. Spring (April and May) brings corbina and warming water. Fall (October and November) offers a second corbina run and cooling water that keeps halibut feeding. Winter (December through March) is slow; water temperatures drop to the 50s, and most species move offshore or feed sporadically.

Tackle and gear setup

A 6- to 7-foot medium-light spinning rod with a 2000 to 2500 reel works well for halibut and corbina. Spool with 10- to 15-pound braided line or monofilament; braided line gives better sensitivity for detecting bites on the bottom. Attach a 12- to 18-inch fluorocarbon leader (8 to 12 pounds) to reduce visibility in the clear lagoon water.

For halibut, use a simple sliding sinker rig: thread the main line through a 1/2- to 1-ounce sinker, tie a swivel, then attach your leader and a size 2/0 to 3/0 circle hook. Circle hooks often hook themselves when a fish runs, reducing the need to set the hook hard. For corbina, use a lighter rig with a 1/4-ounce sinker and a size 1 or 1/0 hook. Bring extra leaders, hooks, and sinkers; the sandy bottom and occasional snags will cost you gear.

Common mistakes and how to avoid them

Fishing too deep is a common error. Many anglers assume deeper water is always better, but in Seaside Lagoon the halibut and corbina often hunt in 4 to 8 feet of water along the edges. Cast toward the shallower areas and the channel transitions, not just the deepest center. Corbina especially prefer water you can almost wade in.

Using bait that is too large or too fresh also slows bites. Small, lively baitfish work better than large mullet or mackerel. If your baitfish is dead or sluggish, replace it. Halibut and corbina respond to movement and scent, so keep your bait active and fresh.

Ignoring the tide is another mistake. Fishing the outgoing tide in summer often means slow action. Plan your visit around incoming or slack tides, and you will see a real difference in bite frequency. Check the tide table the night before and time your arrival accordingly.

Frequently Asked Questions

Do I need a fishing license to fish Seaside Lagoon?

Yes. California requires a fishing license for anyone 16 and older. You can purchase a one-day license online through the California Department of Fish and Wildlife website or at tackle shops in Redondo Beach. The license is inexpensive and covers saltwater fishing statewide.

What is the best time of day to fish Seaside Lagoon?

Early morning (sunrise to mid-morning) and late afternoon (two hours before sunset) are most productive. Halibut and corbina feed more actively during these periods. Midday fishing is slower, especially on bright, calm days. Combine your time-of-day choice with an incoming or slack tide for the best results.

Can I fish from a kayak in Seaside Lagoon?

Yes, kayak fishing is allowed. The lagoon is protected and shallow, making it safe for small watercraft. Bring a personal flotation device and be aware of the tidal channel entrance, where currents can be strong. Many kayak anglers fish the deeper channel and the edges where halibut hunt.

What should I do if the water looks murky or green?

Murky water often means algae bloom or poor tidal exchange. Fish may still bite, but they rely more on scent and vibration than sight. Use live baitfish and work your rig slowly along the bottom. If the water is very turbid or smells foul, consider visiting another day—poor water quality can stress fish and reduce feeding activity.

Is there a size or bag limit for halibut and corbina in Seaside Lagoon?

Yes. California sets size and bag limits for all saltwater species. Halibut have a minimum size (currently 12 inches) and a daily bag limit. Corbina also have a minimum size and bag limit. Check the current regulations on the California Department of Fish and Wildlife website before you fish, as limits can change year to year.
