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.

May Fishing Report
Cool, dry weather. Water temps in mid 70s, getting to high 70s by the end of the month. Early May green water starts to turn blue and clear by the end of the month. The sargasso can be a nuisance at times.
Fishing for Bonita, Dorado, grouper, cabrilla, sierra, Barracuda and some yellowtail. Bottomfishing for snapper. Near the end of the month, skipjack, some billfish offshore and smaller dorado are further out with bigger ones on the way. By the end of May, the yellowtail fishing is usually done.
Good amount of all the bait – anchovies, ballyhoo, flying fish, crabs, and squid.
Wildlife spotting: Thresher Sharks jumping. Fin whales, mantas and maybe Orcas.
San Carlos Fishing Report, May 23, 2023
We’ve had a lot of nice weather, but the catching wasn’t always great. We went from thousands of 6 – 8# dorado, to thousands of 2 – 4# dorado, down to very minimal in a week. I don’t know if they moved, went deeper, or are just full.
There was tons of all types of bait around at times. Also plenty of dolphin out there. We’ve seen a few whales. Lots of manta rays. I haven’t confirmed a sailfish yet. The marlin are definitely around, but judging by the few weak bites I’ve had and only a couple caught, I think that they too are full or turned off by the moon phase.
Some very nice 20 – 40# dorado were caught here. There wasn’t any magic spot. A tournament in Loreto saw 26 over 30# weighed and numerous Striped Marlin released, so be patient.
We filled some bags with bonita, a couple Sierra, and one last yellowtail just off San Antonio Point. I can’t say that the yellowtail won’t bite again on this waxing moon, or a big grouper run.
The water is 76 – 78 F and nice and clear. Summer is here, with a few lingering winter fish to supplement the catch.
San Carlos Fishing Report, May 9, 2023
The fishing is good, but I didn’t hear a lot of reports. Things have probably cooled a bit after the full moon. The water is showing blue and 74 – 75 offshore, but I didn’t hear of anyone trying. We had a couple marlin tickle our baits and may have lost a dorado. I heard of some bonita caught, and we caught our first skipjack. There’s lots of sharks out there, and I saw four working a bait ball. The yellowtail at the Island continued to bite very well.
There is lots of bait in close and I did well off a paddleboard for a variety of species. I caught my biggest ever corvina that weighed 17 pounds.
One big yellowtail boil was seen at San Antonio, but there is lots of seaweed to contend with and most boats fished for calicos. There’s lots of options and great weather in the forecast.

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.
February Fishing Report
Water in the low 60s.
Fishing for Yellowtail, calico, grouper, cabrilla and sierra. Bonita earlier in the month.
Wildlife spotting: dolphin. Maybe Whale Shark, Humpback, Fin Whales, Grey Whales, turtle
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.
January Fishing Report
Water in the mid to low 60s.
Fishing for Yellowtail, bonita, calico, grouper, barracuda, cabrilla and sierra. Yellowtail season is in full swing. You might find some marlin.
Wildlife spotting: Bottlenose Dolphin, Mobula Rays. Maybe Orcas, Fin Whales, Humpbacks.
December Fishing Report
By late December, the water starts to dip below 70 degrees.
Yellowtail season with some big yellowtail starting to show. Tuna (a 100 pound tuna). Skipjack.
Some Sierra, Bonita, snapper, cabrilla and Marlin (a 220 pound Blue Marlin) at the beginning of the month, but the season is pretty much over for them.
Dolphin spotting and maybe the orcas.
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.
October Fishing Report

October 25: San Carlos Fishing Report
Things are starting to slow down after a few busy weeks. The first real front came through on Sunday and water temps have dropped several degrees in the last few days. We were still breaking a sweat with some morning easterly breezes, and a hurricane even went past Puerto Vallarta. Now we are watching snow on the radar and picking our days to head offshore.
The Bonita bite off of San Antonio was pretty good for us most of the week, with some fish near 10 pounds. We went by the east side of San Pedro, and it was loaded with small Bonita. We jigged up one big yellowtail on the North End. One big yellowtail found our 30′ Rapala trolled off a planer board just off San Antonio. A few Sierra were scattered around. It was slow Monday morning, but I think that this wind will trigger the winter fish to start biting.
The water is still plenty warm, but I am thinking that our fish are warm blooded these days. We found some better Dorado on the backside of San Pedro, although some good fish were caught to the south. I think that we will see another wave of the warmer water pull in from the west in a week. There are some Striped Marlin out there, but maybe the Blues have already left. At least I got to watch my 79 year-old friend crank a marlin in today.
Watch the Bisbee results this week. 186 teams just competed last weekend for over $2M in Cabo. A 554# Black Marlin won that two-day event. A few San Carlos teams are down there looking to get a piece of probably $10M.
Inshore fishing continues to improve. Lots of bait is around, as well as all the top predators. My favorite spot was taken over Friday evening. I got pushed to the rocks where four fish that took my live bait parted ways. The other guys got some nice snapper, although I am sure that the corvina were around too. I saw a few pics from the bass lake!
A number of Fin Whales were out Monday, with plenty of mantas jumping. Water temps were still 78 – 79, so not too bad compared to the pics of people with snow in their yards!
October 18: San Carlos Fishing Report
Things are changing quickly, but there’s still time. The billfish seem pretty reluctant again, as well as the Dorado. The Bonita are biting good around San Antonio, and they were running 10 – 11 pounds at times. Most Dorado are small right now, but I did hear of one 25 pound fish caught. We caught one yellowtail on the troll Friday, and friends jigged up a bunch of monsters at San Antonio. There are fish out there to put on the table.
Lots of bait in close, but not a lot offshore. Seeing a few dolphin and one Fin Whale. Lots of manta rays out there. We had one good thrill Thursday with a big 170 pound Striped Marlin ripping a 100 pound line. I thought maybe we finally had a Blue, but I’ll keep hoping. The bite should pick up with the moon phase and there is plenty of clear water out there. Inshore fishing is picking up too. The weather is nice, so go exploring.
September Fishing Report
Water temps in the mid to high 80s and up to 90 degrees on the surface. Summer SE trade-winds.

- 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.
