About Cabo San Lucas

At the tip of Baja, the marina and Medano Beach carry most of the activity, with boats running out to the arch and to snorkelling coves when the swell allows; the Pacific side is rougher and better left to watching. April, May, October and November give warm water and milder air, outside the worst of the summer heat and the late-summer storm risk. Sportfishing and whale watching follow their own seasons, so check what is running before booking.
