Season planner for Cabo Pulmo
Cabo Pulmo is a year-round destination, but your "best" season depends on priorities. Late summer and fall are typically the warmest-water months and can deliver the clearest snorkeling and photo conditions. Winter brings cooler water and sometimes lower visibility, but it is prime time for bull shark encounters and whale migration energy. Plan carefully in late summer when tropical systems can affect Baja California Sur.
