September is often overlooked by casual travelers, but ask any seasoned angler or local captain, and they’ll tell you the same thing: this is one of the best-kept secrets in the Cabo fishing calendar. With the right combination of water temperature, bait concentration, and smart lunar planning, September is a jackpot month.
Let’s dive deep into what species you can expect, where to fish, how the moon affects your chances, and why so many anglers trust Blue Sky Cabo with their fishing dreams.
So, What to Expect Fishing Cabo in September?
Cabo in September is electric. With sea temperatures ranging from 82°F to 86°F, the waters off the Baja Peninsula are loaded with migratory gamefish hunting bait balls. You can expect fast action offshore, exciting opportunities inshore, and a mix of conditions that favor multi-species combos—making September one of the most dynamic months of the year.
Let’s break it down by species, moon phases, top locations, and how Blue Sky Cabo Fishing and Tours elevates the experience.
What Species Are Biting in September?
When you wonder what to expect fishing Cabo in September, the answer is: nearly everything. This month is a transition between summer and fall patterns—perfect for variety and quantity.
1. Yellowfin Tuna
September is prime yellowfin season. These hard-hitting fish roam in schools offshore, ranging from 20-pounders to 200-pound giants.
- Where to find them: Gordo Banks, San Jaime Bank, and around floating debris
- How to catch them: Drone-deployed baits, kite fishing with helium balloons, trolling with cedar plugs
- Why September: Tuna love warm water and are drawn to bait-rich currents and moon-influenced feeding windows
2. Blue and Striped Marlin
Marlin madness continues through September with both striped and blue marlin dominating the offshore scene.
- Top locations: Golden Gate Bank, 1150 Spot, deep water past the Arch
- Tactics: Dredge trolling with teasers, slow trolling live skipjack
- September advantage: Early morning and moonrise periods boost big fish bites
3. Dorado (Mahi Mahi)
September is arguably the best time of year for dorado—plentiful, aggressive, and a ton of fun on light tackle.
- Best zones: Nearshore kelp paddies, offshore buoys, around floating logs
- Methods: Casting jigs, trolling feathers or live sardines
- Why September shines: Transitional currents bring these beautiful fish closer to shore
4. Wahoo
- The silver torpedoes of the Pacific are dialed in this month. Where they hide: The 95 Spot, Pacific drop-offs, Gordo Banks edges
- How to fish them: High-speed trolling with Rapalas, shiny metal lures, and wire leaders
- Why it works in September: Water clarity improves and baitfish scatter, triggering fast strikes
5. Roosterfish
Don’t sleep on inshore roosterfish action. September mornings are perfect for light-tackle nearshore exploration.
- Where to go: East Cape, Chileno Bay, beaches between Cabo San Lucas and San José
- Techniques: Slow trolling mullet or casting poppers
- Bonus: Epic topwater blowups and photo-worthy moments
6. Snapper and Grouper
Deep reef fishing stays productive through September.
- Where: Sea of Cortez rock piles, underwater pinnacles
- How: Bottom bouncing, vertical jigging, or dropping live bait near structure
- Why it’s hot: Stable thermoclines and post-spawn aggression drive feeding activity
How the Moon Impacts Fishing in September
Many anglers overlook the moon, but if you’re wondering what to expect fishing Cabo in September, knowing the lunar phases is crucial.
- Full Moon: Boosts offshore tuna and marlin bite at dawn and dusk due to overnight feeding
- New Moon: Less light = bait stays shallow = more aggressive surface feeding
- First and Last Quarters: Offer balanced tides—ideal for dorado, roosterfish, and wahoo
At Blue Sky Cabo, we read lunar data like a roadmap, combining it with satellite imagery, chlorophyll charts, and sea temp overlays from Terrafin to determine your best chances at glory.
