Fishing Loreto

Loreto fishes the warm, blue water of the central Sea of Cortez, and the chart reads very differently from the open Pacific. This is a protected basin of islands and deep blue channels where warm water, current edges and the structure around the islands do most of the work. The hunt here is less about a hard cold upwelling seam and more about finding the temperature breaks, the color changes and the clean blue water pushing through, often marked where bluer water meets greener or slightly cooler water near the islands.

Structure is the whole game around Loreto. Isla Carmen, Isla Coronado and Isla Danzante sit just offshore with deep drop offs on their edges, and those edges concentrate bait when the current sets up on them. A temperature or color edge sitting over an island drop off is where the pelagics hunt, so pairing the SST and chlorophyll layers with the depth contours is how you find the spot where the warm water, the edge and the bottom all line up.

Seasonally this is a warm water fishery when conditions push in. Dorado work the warm months, yellowtail come up in the cooler months, and marlin and sailfish show through the summer. Roosterfish and jack crevalle run inshore, while cabrilla and pargo hold on the bottom structure. None of it is promised. Warm years and cool years look very different, and seasons and regulations change, so always check current rules.

The move is to watch where the clean blue water and the breaks are setting up relative to Isla Carmen, Coronado and Danzante, and to run to the edge that has the temperature, the color and the island structure all working together rather than chasing warm water with no edge to it.

What you get with ReelTemps

From the water

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.

Loreto FAQ

What am I looking for off Loreto?
Usually the temperature and color breaks where clean blue water meets greener or slightly cooler water, often sitting over an island drop off. It is less about cold upwelling and more about the breaks, the color edges and the island structure lining up.
How much do the islands matter?
A lot. Isla Carmen, Isla Coronado and Isla Danzante all have deep drop offs that concentrate bait when the current hits them. A temperature or color edge sitting over that structure is where the pelagics hunt, which is why the depth layer rides alongside the SST.
What runs here and when?
Dorado work the warm months and yellowtail come up when it cools, with marlin and sailfish through the summer. Roosterfish and jack crevalle run inshore, and cabrilla and pargo hold on the bottom. Seasons and regulations change every year, so check current rules.
Is the Loreto chart buoy calibrated?
No. These are Mexican waters in the Sea of Cortez with no NOAA or NDBC buoys nearby, so there are no in water readings to check the satellite SST against. The chart stands on the satellite passes themselves, so read it for the breaks and the relative temperature changes rather than an exact degree.
