When anglers ask about the transition from summer into fall, one answer stands out—September fishing in Los Cabos. This month delivers warm water, active pelagic species, and excellent opportunities both offshore and inshore.

September blends the best of both worlds for those looking to experience the magic of Cabo fishing.
Why September Fishing in Los Cabos Is Exciting
The charm of September fishing in Los Cabos lies in the diversity of species and the ideal sea conditions.

Marlin Action During September Fishing in Los Cabos
One of the highlights of September fishing in Los Cabos is the abundance of blue and black marlin. These powerful fish are at their seasonal peak, with many ranging from 300 to 700 pounds.

Yellowfin Tuna at Their Strongest
For many anglers, September fishing in Los Cabos means one thing—yellowfin tuna. The offshore banks such as Gordo, San Jaime, and the 1150 Spot produce outstanding tuna action. Schools of smaller football tuna offer steady bites, but the real attraction is the massive cow tuna that can exceed 200 pounds. Kite fishing, chunking, and trolling flying fish lures are all effective methods during this month.
Dorado Fishing Peaks in September
Dorado, also known as mahi-mahi, shine during September fishing in Los Cabos. These brightly colored fish thrive around floating debris, sargassum patches, and offshore current lines.

Their abundance in September makes them a favorite for family fishing trips and sport anglers alike.
Sailfish Add to the Variety
Adding to the excitement, September fishing in Los Cabos also includes sailfish. Known for their spectacular jumps and fast runs, sailfish are frequently caught in the same zones as marlin and tuna.
