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, Sail (300 pound Blue on the reef). Yellowtail, Skipjack, Sierra, bonita (the 15′ purple Rapala seems to be their favorite), some pargo, Roosterfish and Corvina, Snapper, cabrilla. Some dorado, but most have moved well offshore. Tons of bait in close.

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 21, 2023 San Carlos Fishing Report

The yellowtail are feeding good within the first mile of shore. Fifteen to twenty pound fish were biting good at times. They were a little tough on Tuesday though, gorging on schools of the real thing. The bonita were willing to take their place in the cooler. There’s not many of the big ones around, although they are still decent sized. The bite should stay strong for this harvest moon.

The warm water is about 30 miles to the S/SW, but I haven’t heard of anyone making the run. A few Dorado were found in close last week. The shoreline action has cooled off, but the bait is moving around. A few Sierra were in the mix. The bite at the Island is good for those going the distance. Boils have been early, so don’t sleep in!

October Fishing Report

Water temps in the high 80’s at the beginning of the month, then dropping to low 80s. Weather cool to hot throughout the days, with some showers possible. Winds from the Northwest pickup by the end of the month.

Fishing for Bonita, grouper, snapper, cabrilla, sierra, corvina, Skipjack. Yellowtail season starting inshore. Last month for good Marlin, Sail fish & Dorado.

Wildlife spotting: dolphins. Maybe Orcas, mantas, turtle

San Carlos Fishing Report, Oct 25 2023

Fall is definitely breathing down our necks. There are going to be some days that you might want to stay home. The forecast for the week looks good though, so enjoy it while it lasts. Water temps are still in the low 80’s with lots of blue water out there.

I still didn’t hear of much on the billfish front, but plenty of dorado were still around. One 250 pound Blue did get boated. A 51 pound dorado was caught, which is the biggest in the Fall that I have ever heard of. There are some good fish out there, and it sounds like they are schooled up. The bonita took a quick hiatus, but they will be back. Temps will have to drop before we see any yellowtail inside of the Reef.

The shorelines are quickly filling up with bait. Smaller predators were attacking the tiny anchovies, and the rest of the food chain will be right behind. I did get a few corvina, my first since May. Pictures of snow up north are starting to show, so enjoy the late season pelagics while you can.

San Carlos Fishing Report, Oct 10 2023

The dorado fishing is slowly picking up. Every day seemed to have a different bite. I have never before seen them gorging on baby triggerfish. They have them balled up by the hundreds and were stuffed full. Most of them wouldn’t hit a lure or even bait. They were finding safety in numbers, with some large schools forming and many 10 – 20 pound bulls.

The billfish proved to be pretty non-existent all week. One 300 pound Blue Marlin was caught and released. I never saw one of the small Sailfish out there, but a few were caught. There was no sign of tuna, except for skipjack. I didn’t hear of much else caught.

It’s still a touch warm, but the seas were nice. We saw a couple of Fin Whales, but not many dolphin. A few sharks did pass by.

Life is beginning to return to San Carlos.

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.

Still a lot of great weather and catching. More billfish are biting. We released a couple marlin and a sail Tuesday. There were some good dorado caught last week, but I haven’t heard of any big ones caught in the last few days.

A big pod of the Orcas were seen. Lots of dolphin and turtles out there. Plenty of good sized African Tuna. We did catch one big bonita Tuesday. I see the pangas trying for yellowtail. Water temps are still below 80, but maybe not for long!

San Carlos Fishing Report, June 6, 2023

It’s looking like a big dorado year! There are also tons of small dorado, and many are getting to be near keepable size. We landed a 20, 25, 29, and 42 pounders this last week. A dozen were weighed in the tournament from 30 – 39 pounds. There’s lots of bait out there, so they are growing.

The billfish are still finicky, but they are out there too. It sounded like they were down by Haystack on Tuesday. Spots are changing daily.

There’s lots of great weather and the water is staying around 78 F. A little seaweed is showing. The currents are running after the full moon, so we’ll see what shows up!

March Fishing Report

By mid March the water is getting into the mid-60’s.

Fishing for Yellowtail, Red snapper, grouper, cabrilla, sierra, barracuda. Some marlin could come through. Best fishing is often at the Island.

Lots of bait. Seaweed can make trolling difficult.

Wildlife spotting: Large pod of Bottlenose. Maybe Mako shark, turtle, Fin Whale, Orcas, rays

March 15, 2023 fishing Report: The winds look to be calming down, the water is warming up, and life is returning. Cold water is still present in close, but it is warmer offshore. There’s still no reports of yellowtail, although some were seen briefly a few miles out. There’s not a lot of bait, but the bottomfishing has been good. I’ve caught three fish on separate hooks before, but today we caught three calicos all 2.5 – 3 pounds on one jig. We have been getting a lot to 6 pounds and lost one big grouper. We’ll keep at it until the yellowtail return. The life I was seeing was mostly invertebrate jellyfish, sea worms, and other ‘snot’, but you have to start somewhere. Things are going to warm up with the sun as warm as it’s been!

March 1, 2023 fishing Report: There’s still no sign of the yellowtail, but we are eating fish again! A lot of boats are picking up grouper. It helps when you’re bottomfishing, of course. The whitefish/tilefish a.k.a salmón I heard were biting deep. We found some of the best calico Golden Spotted Sea Bass fishing that I have ever seen. They were loving the jigs. Some were going 5 pounds. We did find two small yellowtail in close. The water is a degree or two warmer, so hang in there. Spring is coming.

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.
