In the northern Sea of Cortez, June to October is the core diving season with water temperatures of around 82°F (28°C) and visibility stretching to 35m. Diving is just as good in other months but the water is cooler: experienced cold water divers love it.
Between June and September up to 220 whale sharks arrive in Baja California - it's one of the few places on earth where these giants gather in large groups. Nearby colonies of sea lions (sometimes a thousand strong) enhance the experience even more. You can see turtles, dolphins, rays and jumbo squid all year.
Diving on the other side of Baja California - fronted by the Pacific Ocean - is not as easy to predict but if you keep an eye on conditions and time your trips well the diving is sublime.
