Yellowfin tuna fishing out of Mission Bay is an offshore game, and the local fleet commits full days and longer to it. Seaforth Sportfishing, the Mission Bay landing, sets the pattern with its trip schedule. This guide covers when to look, where boats run, the named grounds, how tuna trips are structured, and the rules specific to this port.
When yellowfin are around Mission Bay
No season is stated for yellowfin out of this port, so there is no published window to plan around. The working signal comes from the fleet.
Watch the Seaforth schedule, which names "Tuna" on its full-day offshore, overnight and multi-day trips. When the fleet puts tuna on those trips, it is committing boats to it. That is an inference from the schedule and not a promise of fish, so treat it that way when you plan your own run.
For the species picture, see our yellowfin tuna guide. For regional context, see the Pacific Southwest yellowfin guide (see also the Pacific Southwest region guide).
Where boats run from Mission Bay
Tuna boats run offshore. The nearshore kelp beds are half-day grounds, and the fleet’s tuna effort goes past them. Its tuna trips are full-day or longer, so plan a private-boat tuna run as a full offshore day at minimum.
Before you leave, check wind, wave height and period in the NWS San Diego coastal forecast and make your own call from the numbers. Chart layers are not for navigation, so run offshore on your own electronics and charts.
For the entrance, ramps and local conditions, use the Mission Bay port guide. If you are new to this port, start there.
- Direction: offshore, past the nearshore kelp
- Minimum commitment: a full day
- Vessel: your own boat, your own electronics
Grounds and structure
Three named grounds sit near Mission Bay. Two are nearshore kelp beds, and the third, the Coronado Islands, lies in Mexican waters.
Point Loma kelp beds
The Point Loma kelp beds are named as a grounds area on the Seaforth half-day trip page. That makes them nearshore half-day water, separate from where the fleet schedules tuna.
La Jolla kelp beds
The La Jolla kelp beds are also named as a grounds area on the Seaforth half-day trip. The same split applies: half-day schedule here, "Tuna" on the offshore trips.
Coronado Islands (Mexican waters)
The Coronado Islands lie in Mexican waters. A run there from Mission Bay means crossing into another country’s jurisdiction. See the Regulations section below.
How yellowfin tuna fishing out of Mission Bay is set up
Seaforth’s schedule names "Tuna" on three trip types:
- Full-day offshore trips
- Overnight trips
- Multi-day trips
Together they show how much time the local effort takes.
Full-day offshore trips
This is the shortest trip the fleet lists for tuna. For a private boat, it marks the baseline commitment.
Overnight trips
The fleet extends tuna effort past a single day, so plan crew, supplies and your forecast window across that span.
Multi-day trips
These are the fleet’s longest tuna commitment from this port and set the upper end of local effort.
Who fishes for yellowfin from this port
Two groups fish for yellowfin from Mission Bay: private boats running offshore and the Seaforth Sportfishing fleet. If you have fished with the fleet, its trip lengths make a ready template for planning your own.
FAQ about yellowfin tuna fishing out of Mission Bay
Is there a yellowfin season out of Mission Bay?
No season is stated for this port. The working signal is whether Seaforth schedules "Tuna" on its offshore trips.
How far do boats run for yellowfin from Mission Bay?
They run offshore, on trips the fleet schedules as full-day or longer.
Do the Point Loma and La Jolla kelp beds hold yellowfin?
Both are named as grounds areas on the Seaforth half-day trip. Tuna appears on the fleet’s full-day offshore, overnight and multi-day trips instead.

No. They are in Mexican waters, so check Mexico’s rules before you go.
