Why Cabo is a World-Class Fishing Destination in September

The what fish are biting in Cabo in September question is especially exciting because this month falls within Cabo’s summer high season — July through December — when the fisheries explode with activity.
In September, warm ocean currents and nutrient-rich waters attract a multitude of pelagic species, ranging from aggressive predators like marlin, tuna, and wahoo to nearshore trophies like roosterfish, snapper, and grouper.

What Fish Are Biting in Cabo in September? Species Breakdown
Answering the what fish are biting in Cabo in September question requires looking at the diverse species actively feeding and available during this peak time.
1. Marlin (Blue, Black, and Striped)
September offers incredible opportunities to hook into marlin. These apex predators patrol the offshore waters, often near temperature breaks or floating debris. Blue Sky Cabo’s expert crews use tournament tackle and high-tech tools like Terrafin satellite imagery to locate these prized fish miles offshore. Whether you’re after blue, black, or striped marlin, September is an excellent month for marlin fishing in Cabo.
2. Tuna (Yellowfin and Bigeye)
Yellowfin tuna are abundant in September, feeding aggressively on schools of baitfish near weed lines and temperature breaks. Bigeye tuna also make appearances in deeper waters. Blue Sky Cabo specializes in high-speed trolling and live bait techniques that maximize your chances of hooking these fast, powerful fish.
3. Wahoo
One of the fastest fish in the ocean, wahoo are a favorite among sport anglers for their speed and fight. September is peak time for wahoo fishing in Cabo. These sleek predators congregate around floating debris and follow baitfish in the warm Pacific waters. Blue Sky Cabo employs shiny metal teasers and drone-assisted bait deployment to give clients an edge when targeting wahoo.
4. Dorado (Mahi Mahi)
Dorado, also known as mahi mahi, are colorful, aggressive feeders that provide fast-paced action. They are found closer to the surface, often near floating debris or weed lines where baitfish gather. September’s warm water and abundant bait make dorado a common and thrilling catch.

Sailfish make seasonal appearances in Cabo, and September often provides exciting opportunities. Known for their spectacular leaps and acrobatics, sailfish add drama to any fishing trip.
6. Roosterfish
