Summer in Cabo also means a bit of extra swell : this attracts surfers of course! June to September are the best surfing months around Cabo.

Mobula rays in Cabo San Lucas

The Mobula Ray Migration

One of the most impressive aggregations of wildlife on the planet comes to Cabo. We swim with huge ‘squadrons’ of Mobula rays in their tens of thousands right inside the bay of Cabo San Lucas.

Only 5 minutes by boat. Incredible! Cabo San Lucas is where the Sea of Cortez meets the Pacific Ocean and we venture into both to search for them. Finding them is easy as they leap, jump and pop out of the water from the depths to create a sonic wave of communication with the hard slap of their landing. As just one theory goes. The Mobula rays behaviour is a visual metaphor of watery popcorn exploding into action; it is both an impressive and unforgettable sight.

We can take you to see these Mobula aggregations between May and August :

Hammerhead shark at Gordo Banks

Gordo Banks

This deep pinnacle is located 25 minutes out of San Jose marina and is a very advanced dive site.

Sightings of schooling hammerheads are frequent among other pelagic animals. Other species of shark have been seen: last year a rare handful of Pacific Sharp Nose were spotted near the surface. Summer is swell season so a deep dive away from the coast is often the perfect option for those who are qualified.

Jacques Cousteau Island

The Jacques Cousteau Island, historically known as Cerralvo Island, this little corner of paradise was renamed after the world-famous ocean explorer who led several expeditions and conservation projects in this area. The deserted island near La Ventana is surrounded by great snorkeling and diving spots that are absolutely perfect for beginner divers. Common encounters here include giant manta, groupers and marlins; at the same time, turtles, dolphins, orcas and mobula rays will be sure to provide the additional thrill.

Bull shark swimming in Cabo Pulmo

Cabo Pulmo National Park

If aquatic life is the focus of your vacation then this ground breaking marine reserve is arguably one of the best places to visit in Baja California Sur. You can do this on a day trip from Cabo.

The Cabo Pulmo National Park gives divers more freedom in the summer months to explore the popular reefs: Reefs that are, by September’s ‘high season’, more restricted in the interests of reducing human impact.

For non-divers wishing to cool off in the heat of the summer a snorkel tour in Cabo Pulmo is one of the best in the area. At Cabo Pulmo dive with Bull Shark and tornado of Jacks, snorkel next to sea lions, visit a beach popular with turtles and swim above beautiful soft coral reefs.

Snorkeling the Bay of Cabo

With higher temperatures and chances of rainfall, the waters fill up with majestic creatures coming to feed off this coast. No need to dive deep to witness the exceptional mobula migration, snorkelers will appreciate the mobulas from the surface. And dolphins will make sure to top it up!

Summer is obviously hot. So combining a tour to the arch with a quick dip at the Pelican Rock reef is a sure way to cool off while making the most of being out on the boat. It’s a short trip so no need to get up too early and you still have the afternoon to sit by the pool. Remember your reef safe sunscreen!

Tours run from 7.30am to escape the crowds up to 2pm.

Weather

The months between June and October are the hot, summer months. The atmospheric temperature starts warming up in June and reaches its peak in August and September, up to 91 degrees Fahrenheit. In Cabo the months of August, September and October are also the rainy season, even though chances of rain are still pretty low – about 20% each day: a little liquid sunshine that will most likely not affect your vacation!

Water Temperature

Snorkeling and Diving is still amazing but until August you may need to don a thick suit. In August the temperature in Cabo San Lucas rises anywhere to 74-82 degrees Fahrenheit.

Water Visibility

The water visibility changes rapidly year round and is hard to predict. However we can predict more days of good visibility between. August to November, water visibility in Cabo reaching up to 100ft+

Do I need a wetsuit to dive in the summer in Cabo San Lucas?

During summer in Cabo any decent tour provider will provide 5mm – 7mm wetsuit for diving and 3mm shorties for activities at the surface, such as snorkeling or observing the mobula migration. A wetsuit is generally always recommended, not only for its insulation properties but also to protect from scrapes and cuts.
