San Carlos Fishing Report

San Carlos Fishing Report with yearly guide, weekly fishing reports and fishing tournament information. San Carlos Mexico has great fishing in the Sea of Cortez. Sports fishing has been popular here for decades with the waters full of big game fish like marlin (3 types: blue, black and striped), sailfish, tuna, and dorado.

What you can hope to catch changes from month to month. Here’s a general break down (see more details in the week-by-week San Carlos fishing reports below):

  • You can find grouper, cabrilla and sierra all year.
  • Bonita: May to December.
  • Dorado: May until mid October
  • Marlin & Sail fish: June through October.
  • Skipjack: June
  • Yellowtail: October through May.

Some of the good local fishing spots: the Island, San Antonio, Seamount (just outside the entrance to Marina San Carlos), Haystack, San Pedro Point, Doble, Deer Island, the Reef, the Horseshoe. Up the coast at Pando, White Rock, Ensenada. Long boat ride out to Tortuga Island. Lake Oviáchic near Obregon is popular for bass fishing. There’s a map on the bottom of this page.

November Fishing Report

Water temps drop into 70s. Occasional storm early in the month.

Marlin in close. Big Sail (300 pound Blue on the reef). Yellowtail outside the Seamounts and around Deer Island. Skipjack, Sierra, bonita (the 15′ purple Rapala seems to be their favorite), some pargo, Roosterfish and Corvina. A lot of the bonita were 6 – 9 pounds, but as the water cools they seem to be getting smaller. Snapper, big cabrilla in close. Some dorado, but most have moved well offshore. Tons of bait in close.

We did find a few larger 10 – 18 pound yellowtail. Trolling within the first few miles for some 9 – 15 pound yellowtail taken on poppers, and jigging worked at times.  We had an invasion of small yellowtail, and they came back on Tuesday. A lot of the fish have big mackerel in their bellies. There is a lot of bait out there. Purple seems to be hot at the moment.

I saw one boil of a thousand or so. Most are in small schools chasing limited bait though. It is still a little warm for them.

The shorelines have been black with bait at times.

Whales, dolphin and leaping rays spotting.

It seems to be a pretty consistent pattern. Get up early, catch a lot of fish, and then spend hours cleaning them.

November 30, 2021 Fishing Report

There was a lot of good fishing, but maybe not everywhere and all the time. The fishing is changing every day, hour, and location. A lot of people were around, but the fishing grounds never got too crazy. I think that some decent bites were found all around.

The warm water pushed in, fairly clear, but I don’t see any enthusiasm left for the pelagics. One marlin was caught by a panga in close on a jig. They may have thought that it was a yellowtail, before the video of it had it come up jumping next to the boat. I saw a 10 pound Dorado on the Seamounts. The warm water pushed in and marlin were hooked incidentally. Some good grouper were caught and usually lost in close. Sierra were around, and a ton of Bonita at times. The yellowtail went nuts on the surface at times, and were pushing 17 pounds.

Deer Island still had its fish. They were found all over in close at times. The Island had some good catches of larger fish. There were no reports from up the coast. It was great weather and the fishing was hopefully a bonus!

November 24, 2021 Fishing Report

The bite was decent for most of the week. We managed a yellowtail or two a day and a lot of Bonita. A few marlin and Dorado were out there and pushed in close, but I didn’t hear of anyone targeting them. We chased one on Tuesday inside the Bay. I still think that we may see some warm water move up the coast in the next few days.

Friends found good fishing for large yellowtail on jigs, poppers, and trolling at San Pedro at times. Another boat found world-class yellowtail fishing at Martir, with one going 25 pounds. The boat next to us found a couple cabrilla going up the coast.

The Bonita are still running a pretty good size. The Seamounts was the spot as of press. A few decent Sierra found their way into my smoker. The yellowtail were mostly in close for us, and the last couple were right along the Tetekawi and Doble. Some corvina are in the harbors still. Lots of great weather and the boats will be busy this week!

October 26, 2021 Fishing Report

We are slowly progressing into the winter fishing. The water is still in the upper 70’s offshore and is fairly clear, but it is sad to watch the blue 80 degree water slowly leaving. On Tuesday it was almost 28 miles out, but I thought that I could start to see a plume forming that could push back our way.

The Dorado are scattered around in the ‘green’ water. I didn’t hear of any sailfish, but some marlin are still out there. Some of the Dorado are 10 – 20 pounds, but 6 – 8 pounds Dorado are still the big ones. They will survive the next few days of wind. If they find the bait they will stick around.

Yellowtail were jigged up at the Island. I haven’t heard of anyone looking for them up the coast. They don’t seem to be around here at the moment, but the Bonita were biting very strong Tuesday with many going 10 pounds. A lot of 2 – 4 pound Sierra are in the area, and we did get an 8 pound monster. I caught some very large corvina last week from the shore. It’s a great time of year to be in San Carlos!

  • 2020 & 2021: cancelled
  • 2019:  32 boats and 101 anglers. A boat had released 14 marlin a little farther out on Friday. Several of them were Blue Marlin, and they saw one big enough for us to win the grand prize of a new truck. We picked up a few marlin that day, but the hot bite was found mid-afternoon farther out. We passed a few on the surface Sunday, catching the first fish of the day, but we only released two more that day. We were getting closer to a hot area the previous day at 35 miles, but the bite exploded 5 miles inside of us. We did hook one there that upon the initial jump looked big enough for the truck, but it was probably only 175 pounds.
  • 2018: 26 boats competed in the 71st International Billfish Tournament. The grand prize was for a truck with a 200+ pound marlin. We had the big gear and 16 – 20″ lures out. We ran a lot of skirted ballyhoo too, which got the bites. Telamon won with about four marlin and a sail release.
  • 2017: 70th Anniversary of Ernesto Zaragoza International Billfish Tournament. back & white photo below is from the 3rd International Billfish Tournament in 1950

San Carlos Fishing Report: June 23, 2021

The bite is finally good. We were beginning to wonder about things. The fish were just swiping at the baits and repeatedly dropping them, now they are taking it down. There are still some reluctant fish, but there are plenty of players. Some larger marlin, sails, and Dorado are now here.

The large Dorado may be showing offshore after the last good blow. A lot of fish are within the first few miles, so it’s a tough decision to make a long run out. The Reef has had some fish. A few Bonita were still caught, but they may be going deep. The fish have been hitting the lures and teasers, but bait still rules.

Some 200 – 250# marlin were lost within a mile of shore. I see good Dorado being caught to the far south. One friend caught a 51 pound Dorado out of La Paz. The shoreline corvina fishing picked up, before the seaweed got stirred up. I heard of some big triggerfish caught. Some good weather is in the forecast, so hopefully there will be a good full moon bite.

San Carlos Fishing Report: June 16, 2021

The fish were found all over last week, and nowhere. Some concentrations of small Sailfish and Dorado were found in close, but they weren’t too hungry. The Reef, Island, and far to the south had a few catches.

I have never seen the bite near this tough. They would repeatedly drop the baits, or not hit them at all. Hopefully they are just going through a phase.

The ladies held a little tournament on Saturday. I think that only a billfish or two were released. One 26 pound Dorado was caught. Most Dorado seem to be running under 5 pounds, but I think that some larger ones will show soon.

Bonita continued to bite in close. Most were small, but some were 6 – 8 pounds. Sierra too were caught inshore. Things are getting warm, but it is still nice on the water and I think that the best is yet to come.

San Carlos Fishing Report: June 9, 2021

A lot of nice fishing days, but we are waiting for summer I guess. The south winds should come in this weekend, and we’ll see if that changes anything. The seaweed, flying fish, and bigger Dorado are to the south, or slipping up the other side. We are mostly seeing billfish and small Dorado here.

Most boats have stopped fishing for Bonita, but they are probably there. A very unusual find is the preponderance of sailfish in close. On Sunday we passed one a half mile off Deer Island when heading out. The next day we passed twenty, just a quarter mile off San Antonio. They certainly weren’t biting well, along with the small Dorado. I guess that they are full, or just used to slashing small bait. I even heard of one guy catching one off a zodiac inside of Window Rock. We had dozens of bites, but they didn’t even want to usually take a second swipe.

Reports farther out were usually limited, as far as the catch. Boats tried all directions, with some bigger billfish caught. I didn’t hear of any consistently good areas, although I did hear of one boat releasing five marlin and a sailfish. If the bite turns on in close, it will be pretty cool. It’s very special to be able to catch fish just minutes out of the harbor. In many areas you have to run for hours to get to the fish in rough conditions, and usually at a much greater expense. Some turtles, rays, and dolphins are out there. The water is very clear and warm this year and there is a lot of feed for the fish.

San Carlos Fishing Report: June 2, 2021

The sailfish, marlin, and Dorado moved in close last week. We were jigging in close and had a marlin swim by. Yellowtail were slim, but some decent sized fish were found. The Bonita were mostly small, but numerous at times. At least they allowed us not to have to keep the baby Dorado.

Dorado were everywhere, but few over 5 pounds. One friend did go 100 miles south, and caught a handful from 25 – 40 pounds. The billfish were small here too, but they were plentiful.

The fish are filling up on all the bait out there. Hopefully they will be hungry again soon!

Yellowtail Tournament, every February or March

  • 2020 & 2021: cancelled
  • 2019: 13th Annual Yellowtail Fishing Tournament. Many braved the high seas and went over to the Island. Most boats caught 2 to 4 yellowtail, although Team Catch-a-lotta weighed 9 yellowtail weighing 150 pounds, and the big fish of the day at 21.5 pounds. Their luck wore off for Sunday, losing the one fish that they needed to win. Team Fins Up weighed six good fish, and the big fish of 22 pounds for a second consecutive win. A few teams caught a number of smaller fish up the coast, and jigging off Lalo’s.
  • 2018: Thirteen boats fished the worst tournament ever. The weather was at least good on Saturday, where Fins Up won the tournament with six fish, and the biggest at 26.2 pounds. Only four other fish were caught that day, and seven on Sunday. Fins Up caught two other fish for a total of 151 pounds. The next biggest fish were 22.2 and 20 pounds. I think everyone still managed to have fun though.
  • 2017: 11th Annual Yellowtail Tournament. We had 14 boats and 49 anglers. Catch-a-Lotta took Day One with ten of their largest fish weighing 158 pounds, and the biggest of the day at 19.77 pounds. Day Two saw Zancudo weigh in at 132 pounds to take third being Telamon. Catch-a-Lotta held on to win with 220 pounds. Play Time weighed in the big fish of the tournament at 22.86 pounds. Day One saw rough conditions, but Day Two saw most every boat at San Pedro for some decent catching.
  • 2016: 12 boats and 47 anglers. Day One saw very slow fishing after great reports the previous day. All the good reports had been coming from up the coast. That day though the fish came up at San Antonio where a few fish were caught. Many boats tried the Island where there was tons of bait and hopefully the big one for the jackpot. The Saturday jackpot though was won up the coast with a 14.1 pound fish. The total for the day was also taken late up the coast by Warpath. The bite was found up there again, with the best action 25 miles away at White Rock. The fish were chasing bait on the surface and several boats loaded up with limits of nice fish on poppers and jigs. In the end, Warpath took the day again, and the tournament with 185 pounds for their 15 fish. One other nice check though went to Rod Tuggers for their 19.1 pound yellowtail. I think everyone had fun in the nice weather.
