Fishing Baja Pacific South / Mag Bay

Baja Pacific South is the Magdalena Bay country, and it fishes warmer and more open than the island zones to the north. Off Cabo San Lazaro and the entrance to Mag Bay, out to Thetis Bank and the Ridge, you are working offshore banks, drop offs and the color lines where warm blue water meets greener, cooler or bait rich water. The chart here is about finding the temperature breaks and the chlorophyll edges offshore, because this is a pelagic fishery where the fish follow the clean water, the edges and the bait schools rather than hugging a cold coastal seam.

Structure still matters offshore. Thetis Bank and the Ridge are the classic high spots, and the banks and drop offs outside the bay concentrate bait when the current and the breaks set up on them. Cabo San Lazaro and the entrance funnel water and bait in and out. Pairing the SST and chlorophyll layers with the depth contours is how you find the spot where the temperature edge, the color change and the bank all line up, which is where the bait balls and the predators tend to stack.

Seasonally this area is famous for its fall striped marlin concentration, when fish tail on the surface and work balled bait in big numbers in good years. Yellowfin tuna from footballs on up, wahoo and dorado round out the warm water fishery, and anglers often launch from Puerto Lopez Mateos to reach the grounds. None of it is promised. The run timing and the water shift year to year, and seasons and regulations change, so always check current rules.

The move is to use the chart to find where the clean warm blue water, the temperature break and a color edge are setting up over Thetis, the Ridge or the outside banks, and to run to that edge where the water and the structure meet, rather than chasing open blue water with no break or bait under it.

I've tried every temp map out there and they all feel like they were built ten years ago. I'm not exactly a tech guy, but this one actually makes sense the second you open it. First time using it, I marked a break in about 30 seconds the night before and boated bluefin right on it the next morning.

Used to burn half a tank driving around looking for color change or a solid temp break. Now I check ReelTemps before I leave the dock and I know exactly where I'm going. Less time driving around guessing, more time with lines in the water.

Albacore season used to mean a couple hours of homework the night before and just hoping it held up. Now I do most of my research that morning and pull it up on my phone if things change once we're out there. Makes calling an audible a lot easier.

Baja Pacific South / Mag Bay FAQ

What am I looking for off Mag Bay?
The temperature breaks and the chlorophyll color edges offshore, where warm clean blue water meets greener, cooler or bait rich water. This is a pelagic fishery, so you are reading the edges and the bait lines over the banks rather than working a cold coastal seam.
How much do Thetis Bank and the Ridge matter?
They are key. Thetis Bank, the Ridge and the outside banks and drop offs concentrate bait when the current and the breaks set up on them, and the entrance at Cabo San Lazaro funnels water and bait. A temperature or color edge sitting over that structure is where the fish stack, which is why the depth layer rides alongside the SST.
What runs here and when?
Mag Bay is best known for its fall striped marlin concentration, with tailing fish and balled bait in good years, plus yellowfin tuna from footballs on up, wahoo and dorado. Many anglers launch from Puerto Lopez Mateos. Run timing and seasons and regulations change every year, so check current rules.
Is the Baja Pacific South chart buoy calibrated?
No. These are Mexican waters with no NOAA or NDBC buoys off Mag Bay, so there is no in water station to compare the satellite SST against. The chart stands on the satellite passes themselves, so read it as relative breaks and edges rather than an exact water temperature.
