The short answer to when is fishing season Cabo is: all year. The better answer is that the best time depends on what you want on the line. Cabo sits where the Pacific Ocean meets the Sea of Cortez, giving anglers access to changing water temperatures, migrations, and a seriously impressive mix of game fish. Whether you are chasing a bucket-list marlin, bringing the family out for a few hours, or looking for fresh fish tacos after a successful day, there is a great window for your trip.
When Is Fishing Season Cabo at Its Best?
Cabo fishing never really shuts down, but late summer through fall is the headline season for many visitors. From roughly August through November, warm water brings some of the biggest offshore opportunities of the year. Blue marlin, black marlin, striped marlin, sailfish, yellowfin tuna, dorado, and wahoo can all be in the mix.
That does not mean you should only book a fall trip. Winter and spring are famous for striped marlin, while roosterfish and inshore action can make spring and early summer especially fun for anglers who would rather stay closer to shore. Your ideal season comes down to your target species, trip length, and how flexible you can be with weather.
Summer and Fall: Big-Game Cabo Fishing
If your dream is a large offshore fish, plan around August, September, October, or November. These are some of Cabo’s warmest-water months, and the pelagic bite can be outstanding. Yellowfin tuna can be a major draw, particularly for experienced anglers willing to head farther offshore when conditions call for it. Dorado are colorful, fast, and a favorite for groups because they often provide lively action as well as excellent table fare.
Marlin are the stars of the show. Cabo is known worldwide for striped marlin, but the warmer months can also produce blue and black marlin. No charter can promise a specific catch, of course. Fish move, bait changes, and conditions matter. Still, fall offers the strongest overall lineup for travelers hoping for a true big-game day.
There is one practical trade-off: late summer and early fall can bring heat, humidity, and occasional tropical weather. A good local captain watches marine forecasts closely and will prioritize safety. If you are visiting during this period, keep your fishing day flexible rather than making it the only activity you can move around.
Winter: Striped Marlin Season
December through April is prime time for striped marlin in Cabo. The cooler Pacific waters create a reliable winter pattern that attracts anglers from across North America. Striped marlin are known for their acrobatic runs and dramatic jumps, which makes them exciting even for first-timers.
Winter is also a comfortable time to be on the water. Mornings can be cool enough for a light layer, while afternoons are usually sunny and pleasant. For couples, friend groups, and visitors planning a fishing trip around a winter escape, this is one of the easiest times to enjoy a full day offshore.
You may find fewer warm-water species than in September or October, but that is not necessarily a downside. If striped marlin is your priority, winter is hard to beat. This is a great example of why “best season” means different things to different anglers.
Spring: Roosterfish and Nearshore Action
Spring, generally April through June, is a strong choice for anglers interested in roosterfish. These distinctive inshore fish are famous for the tall, comb-like dorsal fin that gives them their name. They are powerful, aggressive, and commonly targeted along beaches and rocky points around Los Cabos.
Roosterfish are usually catch-and-release, which suits travelers who want the thrill of the fight without planning to keep fish. Spring can also offer good chances for jacks, sierra mackerel, snapper, and other nearshore species, depending on the day and location.
This season works particularly well for families and newer anglers. A shorter inshore trip can feel less intimidating than a long run offshore, and there is still plenty of action. It also leaves room in the day for the beach, a sunset sail, or dinner in Cabo San Lucas.
Early Summer: Warm Water Starts Building
June and July are transition months. Water temperatures begin climbing, and the offshore menu starts to expand. Dorado, tuna, wahoo, and billfish may begin appearing in greater numbers as bait and currents shift. The exact timing changes from year to year, which is why local, current information matters more than any fixed calendar.
Early summer can be a smart choice for travelers who want a mix of possibilities without the busiest fall crowds. It is also a good time to book a private charter if your group has different goals. One person may want to troll for marlin while another wants a shot at dorado for dinner. An experienced crew can tailor the plan to the conditions and your priorities.
Pick Your Cabo Fishing Trip by Species
Rather than choosing a date first, think about the fish that would make your vacation story. Striped marlin are most associated with late fall through spring. Blue and black marlin are more likely in the warmer months, especially late summer and fall. Yellowfin tuna, dorado, and wahoo are often strongest from summer into fall, although fishing is never a perfect schedule.
Roosterfish are a major draw from spring through early summer, while bottom fish and nearshore species can give anglers options throughout much of the year. If bringing home fish for a meal matters most, ask about what is currently biting and what can legally and responsibly be kept. Your captain will know the local rules and can explain what to expect before leaving the marina.
What to Know Before Booking a Cabo Fishing Charter
The best fishing trip is not always the longest one. A four-hour charter can be ideal for younger kids, cruise visitors, or anyone who wants to test the waters. A six- or eight-hour trip gives the captain more time to find fish and is often the better bet for offshore species. Full-day trips make the most sense when tuna or large marlin are your main goal and the fish are running farther out.
Ask whether your charter is private or shared, what is included, and whether bait, tackle, licenses, and cleaning the catch are part of the price. Many Cabo charters handle the fishing license process, but confirm that detail in advance. Also ask about transportation, especially if your hotel is in the Tourist Corridor, San Jose del Cabo, or farther away.
Sea sickness can sneak up on people who feel fine on land. Eat lightly, hydrate well, and consider motion-sickness medication before boarding if you know you are sensitive. Early departures are normal because morning conditions are often calmer and bait is freshest. Bring sun protection, a hat, sunglasses, and a light layer for the ride out.
At Cabo Discount Tours, fishing experiences are personally tested and recommended, so travelers can spend less time sorting through unfamiliar operators and more time getting excited about the day ahead.
The Best Month Depends on Your Cabo Vacation
For a classic winter getaway with striped marlin potential, choose January through March. For roosterfish and inshore variety, look at late spring. For the biggest all-around offshore lineup, target August through November. If your dates are already set, do not worry. Cabo’s year-round fishery means a good captain can still build a worthwhile trip around what is active when you arrive.
Book early if you are traveling during peak vacation weeks, tournament season, or with a larger group. Then let the conditions guide the day. The fish do not read the calendar, but the right crew knows how to put you in the best position to make a Cabo fishing memory worth bringing home.
