The months of December through March are the best time to whale watch in Cabo San Lucas. These are the months the whales are giving birth and rearing their newborns in the calm bays and lagoons along the coast. In fact, whale watching tours are so confident you'll see whales at this time, most offer a whale sighting guarantee.

The best way to get up close to the whales is by boat. You can head out in inflatable Zodiac-style boats or larger vessels with covers for a more comfortable and traditional experience. From shore, Magdalena Bay Whale Sanctuary and San Ignacio Lagoon are your best bet for sightings.
