Spring Wildlife in Los Cabos
February and March are my favorites for whale watching, as well as for getting super lucky and seeing whales on scuba dives at Gordo Banks, Lands End, Whales Head, and some other sites if you’re super lucky! By this time, the young calfs are much more curious and playful and the mothers are starting to let them explore a bit more. So we usually see them breaching a lot! The hammerheads at Gordo Banks also tend to be in full force as the water cools, bringing them closer to the surface.
April and May are the coldest temperatures underwater, but these cool nutrient rich waters bring in all sorts of amazing creatures. For one they kick off the largest aggregation of rays on our planet – Baja’s annual mobula ray aggregations. These schools can number upwards of 10,000 individuals. The schools won’t arrive in Cabo until a bit later, but I highly recommend checking out a Mobula Ray Expedition to go spend a few days with the rays at a secret spot. I have yet to find another encounter on earth that even rivals being in the water with thousands of mobulas rays peacefully gliding through the waters. It will honestly change your life. Mobula ray season is also a great time to spot Orcas as they come in to hunt the rays.
The cold nutrient waters kick off all an incredible chain reaction of life from giant schools of jacks and snapper to even some of the largest creatures on earth. In Cabo, during the cold months I’ve had all sorts of rare encounters with weird creatures from massive spider crabs roughly 1 meter (3ft) wide, small tooth sand tiger sharks, oceanic manta rays, horn sharks, sailfish, and even massive whale sharks cruising past Pelican Rock 20m (70ft) underwater. April is also a good time to spot the elusive smooth hammerheads on open ocean safaris and the bull sharks in Cabo Pulmo National Park. The bull sharks can be seen almost all year long in Cabo Pulmo, except in the autumn when the waters get really warm. During this time the bull sharks will tend to head a bit deeper looking for cooler waters.
