Yellowfin tuna fishing out of Oceanside runs through summer and fall, with full-day and multi-day trips leaving the Oceanside Sea Center landing for offshore water. If you keep a boat in Oceanside Harbor, this page gives the port’s numbers: timing, the distance and depth of named structure, how the local fleet works the fish, and who runs the boats. It covers numbers only and makes no promises about catches. For how yellowfin feed and move, see the species guide.
When Yellowfin Are Here Out of Oceanside
The season is summer and fall. A Blue Horizon full-day trip out of Oceanside Sea Center recorded 35 yellowfin in October. The landing publishes counts by boat and trip on its Oceanside Sea Center fish counts page, and those counts are the best local indication of whether the bite is on before you commit fuel.
Key points for planning:
- Season: summer and fall
- Trip format on record: Blue Horizon, full-day offshore
- Count on record: 35 yellowfin in October
- Where to check counts: Oceanside Sea Center, by boat and trip
Where Boats Run and the Structure Off Oceanside
Yellowfin boats run full-day and multi-day offshore trips from the Oceanside Sea Center landing. For the wider region, see the Southern California offshore picture (see also the Pacific Southwest offshore fishing guide). Named structure off Oceanside falls into two groups: nearshore reefs and kelp in 42 to 100 ft, and offshore high spots in 1309 to 1923 ft at 24 to 30 nm.
| Name | Type | Depth or depth range (ft) | Distance from Oceanside | Build details |
|---|---|---|---|---|
| Offshore high spot 312 | Offshore high spot | 1923 | 24 nm | n/a |
| Offshore high spot 181 | Offshore high spot | 1309 | 30 nm | n/a |
| Oceanside Artificial Reef 2 | Artificial reef | 42 to 72 | not listed | 1987, quarry rock, 10,000 tons |
| Oceanside Artificial Reef 1A | Artificial reef | 82 to 100 | not listed | 1964, quarry rock, 2,000 tons |
| Oceanside Artificial Reef 1B | Artificial reef | 45 to 90 | not listed | 1987, concrete dock floats |
| Barn Kelp | Kelp bed | not listed | not listed | n/a |

Reef depth ranges are from the CDFW artificial reef list.
Offshore High Spots
High spot 312 sits 24 nm from Oceanside in 1923 ft. High spot 181 is 30 nm out in 1309 ft. The 6 nm gap between them is the figure to use when planning range. Both appear by name in the app’s Chart Contours layer. Chart layers are not for navigation.
Nearshore Reefs and Kelp
Oceanside Artificial Reefs 2, 1A and 1B sit in 42 to 100 ft per the CDFW list, and Barn Kelp is a named kelp bed. Reef 1A is the oldest, built in 1964 from 2,000 tons of quarry rock. Reef 2 is the largest, built in 1987 from 10,000 tons of quarry rock. Reef 1B was built the same year from concrete dock floats.
How Yellowfin Are Fished Out of Oceanside
The local fleet works yellowfin on full-day offshore trips and limited-load overnight trips. Blue Horizon trips provide rental tackle, and its site notes side-scanning sonar and fish finders aboard. For other approaches, see techniques for other tuna species.
The two formats:
- Full-day offshore: leaves the Oceanside Sea Center landing and returns the same day
- Limited-load overnight: a longer trip with a capped passenger count
