Tuna Fishing in San Diego: An Early April Offshore Bite

April is when tuna fishing in San Diego starts to show its hand. Winter is still close enough to keep crews cautious, but the signs of a real season begin to appear. Water changes. Bait shows up. Fish stop being rumors and start being results.

April 2023 delivered exactly that.

Mixed-grade bluefin tuna on deck. Kelp paddy yellowtail cooperating early. A bite that felt active instead of tentative. Add in new bottom fishing regulations that required a thoughtful approach, and the day became less about chasing headlines and more about reading conditions correctly.

This was the kind of trip that tells you the season is waking up.

Early-Season Tuna Fishing Sets the Tone

Early April offshore fishing is rarely about nonstop action. It is about confirmation. Are the fish there? Are they moving? Are they willing to bite under real conditions?

The bluefin tuna answered those questions.

Mixed-grade fish are typical this time of year, and they are valuable. Smaller bluefin keep rods bent and anglers engaged. Larger fish mixed in raise the stakes and reward patience. Together, they create a balanced offshore day that feels productive without being chaotic.

This is the stage of the season where decisions matter more than speed. Knowing when to stay in a zone and when to move can be the difference between a slow grind and a steady bite.

On this trip, the signs were clear enough to stay committed.

Kelp Paddies Add a Layer of Opportunity

Kelp paddies in April are hit or miss, which makes them worth checking. When they hold fish, they can change the pace of the day quickly.

Yellowtail showed up on the paddies, adding urgency and variety. Kelp paddy fishing demands focus. You slide in, lines go out fast, and the window can close just as quickly as it opens. When it works, it rewards decisiveness.

That contrast is part of what makes early-season trips interesting. Offshore tuna require patience. Kelp paddies demand speed. A crew that can move between those modes without hesitation keeps the day moving forward.

Got very lucky to catch a ride on Noah's boat last week. We caught 2 blue fin tuna thanks to Noah. Once ina lifetime experience for me. He was on it. Got us hooked up immediately. Very lucky.
Very efficient in handling and maintaining the quality of the fish. Couldn't be happier.
Thank you!
Brothers Sportfishing is top quality operation all around! From booking our trip, communication leading up to our trip, then with the service during our trip. Our Captain was Noah. He was professional, courteous, and was a joy to fish with. He worked hard to put us fish and communicated what was happening and where we were going throughout the day. We ended our day with a 151# BFT (dressed). All thanks to Noah’s knowledge, experience, and dedication to our group. I can’t say enough about the great experience we had with Brothers Sportfishing. Thank you Scottie and Noah!

Capt. Noah put us on Yellowtail for the Coronado 3/4 trip. He made a valiant effort to keep us in the action. We've had other guides who don't appear to be fishermen at heart but Noah stopped the boat on the way back in to throw, lol, just one more cast 😆. That's the guy you want to fish with! Great service, great experience, great fishermen.

Thanks Scottie and Noah!

Captain Travis and his deckhand Bennet were awesome!!! My two daughters, my wife and I truly enjoyed our time on the water. Captain Travis’s knowledge and skills helped us reel in four sharks. We did release the reef shark back into the water. Thank you Captain Travis and Bennet.

We booked a half day trip to celebrate our son’s birthday with Brother Sport Fishing. All of us are beginners in ocean fishing. However, Captain Travis and Jackson made it easy for us. They did a good job finding the fishes and showed us how to catch them. It was a great experience and we highly recommended them!!!

We had the most amazing trip with Capt. Zeek! My husband just finished 5 rounds of chemo and is heading into a bone marrow transplant next month. Before we did that, we decided to do something that has been on our kids “bucket list” with their dad for the past 7 years. It was definitely an unforgettable trip! We were told that we “might” catch a yellowtail but it would be really hard. We didn’t just catch 1, we caught 3!! Zeek made it fun and entertaining. He was a great captain and even let the kids drive the boat occasionally! The day was gorgeous, and we all had a blast! We also saw a pod of dolphins, a snapper shark and seals. It was something we will all talk about for many years!! I would definitely recommend Zeek and hopefully once my husband is good and strong again, we will do it again! Amazing trip!

I've booked trips twice with brothers fishing, both times with captain Zeke and both times did not disappoint. He takes care of literally EVERYTHING for you. All you have to do is sit back and fish. My last trip was a shark excursion and we ended up hooking on an almost 6ft blue shark. These guys know what they are doing and Capt Zeke knows how to captain a vessel and always puts you in the fish. Highly recommend.

Captain Travis was a pleasure to fish with during our 12hr Coronado Islands trip. My 16 and 14 y/old sons and I had a great time. Travis cleaned a few fish to be cooked by a near-by restaurant and made arrangements to process the rest of our catch. Much appreciated!

Had a fantastic February day out with Captain Cruz! Zeek tried his hardest to get us on fish, was extremely chill with our lack of experience on the ocean but also realized that everyone in our group had ample angling and boating experience. We saw some pretty amazing stuff and came really close to catching a yellowtail in an abnormal time to even see them. Also saw a school of yellowtails beating up a Blue Shark! We also got into a mixed bag of bottom fishing that we all felt was very successful outing. Scotty got us hooked up right and will hopefully use this group again when life gets me back to San Diego.

For a fisherman with little experience on the ocean, we couldn’t have asked for a better experience. Brothers were so professional and responsive with the organization of our trip and Captain Noah made it all happen on the water. He allowed us to ask all the “dumb” questions and paralleled our approach to the fly fishing we do in the northwest. We got descriptions on fish species, ocean behavior, and our lines were baited constantly. The fish got processed so perfectly that the filets were Lilly white. As I type this I am actually eating the Seviche recipe captain Noach gave us for the Vermillion rock fish. We probably made 20 drifts over fish rich sections and hooked up nearly every drop of the line. Seriously, we tried to remember how many times we dropped bait and didn’t catch something. At most we missed three times over a 9 hour trip. We cannot wait to return. Rock fish, ling cod, white fish, shark. BTW-we saw a whale. It was awesome.

Captain Travis deserves a raise!!
Boat was perfect… Captain was epic in his knowledge. We were 25 fish deep at the three hour mark. I am always looking for an excuse to charter a boat, and BSF makes it easy.

Fishing Within New Bottom Regulations

April 2023 also brought new bottom fishing regulations into the picture. Adjustments like these force crews to be more deliberate with their planning. You cannot rely on old habits or fallback options.

Instead of limiting the day, the regulations sharpened the approach. The focus stayed on offshore opportunities, with bottom fishing decisions made carefully and within the new framework.

That kind of adaptability matters early in the season. Conditions are already changing.

Regulations are part of the equation, whether you like them or not. The crews that succeed are the ones that account for both without letting either dictate the entire day.

Why Early April Trips Matter

Trips like this do not always produce the biggest photos or loudest reactions. What they produce is confidence.

For anglers, that matters. For crews, it sets the tone for the months ahead.

Tuna fishing in San Diego is not defined by one explosive moment. It is built through steady progression. April trips are where that progression becomes visible.

This day delivered mixed-grade bluefin, cooperative kelp paddies, and a clear signal that offshore fishing was lining up the way it should. Not because everything went perfectly, but because the crew stayed flexible and read the conditions honestly.

Those are the trips that set expectations for the rest of the year.

When early April produces days like this, it is not about what already happened. It is about what is coming next.
