Diving Mexico (Western) articles, reviews, and reports from Undercurrent

Diving Mexico (Western) Overview

Diving the sea mounts of the Sea of Cortez can yield sea lions and occasional schooling hammerheads, though fishing continues to wipe out the big fish. Still, there's good diving from Cabo Pulmo to San Lucas and even farther north operators are getting to the seamounts. In winter and spring water temperatures can drop to the low 60s. Visibility is lower (25-40 feet), but generally improves to 80 to 100 feet by late summer, when the water warms to the 80s in the Sea of Cortez. From December through May winds kick up the water, which makes diving difficult. Wear a skin or wetsuit for protection from jellyfish. Diving Socorro Island gives you hammerheads and mantas, though it's a long ride from Cabo and there's no guarantee of sharks or good weather. Manta sightings are reliable and they have a reputation for letting divers approach. One can fi nd good accommodations and food at all the dive venues north of Cabo. Farther south, Pacific diving is dulled by low visibility.

Mexico (Western) Seasonal Dive Planner

A one-word description of Sea of Cortez diving: variable. Water temperature and visibility varies dramatically. Two divers returning from the Baja only weeks apart can give such different reports that you have a difficult time believing they've been to the same destination.

In the southern part of the Sea of Cortez, the temperature of the upper 30' of water or so remains warm enough year-round (70° to 80s) to support tropicals and several varieties of hard coral. Below that depth, winter and spring water temperatures in the 50s and 60s freeze out the tropicals. From mid-summer through November, water temperature is 80°F or higher for as deep as sport divers would care to go.

During spring and summer, the surface water temperature rises, of course, but the big change is the lowering of the thermocline. This is a complex and uneven process. During a June visit, the thermocline was at 45-50'. Sometimes the change was gradual or of small magnitude, but on one dive we recorded a plunge of 16 degrees between the surface, at 76°, and a thick layer of 60° planktonic green gloom 50 feet down. Later in the season, the water is 80° all the way past 100'. (We've even recorded 84° water in October.)

Another seasonal variable is the plankton concentration. Sometimes the more plankton-rich waters can be observed as distinct layers and masses. Generally, our June visibility was 30-40'. Later in the summer, it's usually 80-100'.

After the first of December, north winds often make diving difficult because of rough seas. Sport diving effectively ceases until May. By spring the thermocline is high and a 1/4" wetsuit is recommended (some sort of protection from jellyfish is recommended year-round). Tropical storms can occur during summer and fall, just as in the Caribbean. On average, they are most likely from mid-September to mid-October. La Paz and its waters tend to be protected from storm swells by a projection of land on the east and by large islands such as Isla Cerralvo.

It's almost always sunny, but during the winter, night air temperatures can drop down into the mid-fifties. Hottest months are August and September. Whale season is December to March.
