During autumn, visibility can sometimes exceed 100 feet. This is the optimal time to clearly see the 800 species of marine life and the 20,000-year-old hard coral reef.

When is the best time to dive with bull sharks in Cabo Pulmo?
Winter, from December to April, is the peak season for bull sharks.
Bull sharks congregate around the El Vencedor shipwreck site during these cooler months. Because this is a highly popular dive, advance booking is essential in the winter. Spots fill up quickly.

When can you see whales in Cabo Pulmo?
Whale watching peaks from December through April.
As the water cools in the winter, migratory whales pass by the Baja California Peninsula. You can often spot them from the boat while traveling to snorkel or dive sites.
Is there a specific season for snorkeling?
Snorkeling is excellent year-round, but autumn offers the most comfortable conditions.
If you visit in late September through November, the warm water means you likely will not need a wetsuit. During the cooler winter and spring months, you will want a 3mm or 5mm wetsuit to stay warm.


How does the season change what I need to pack?
Winter requires thermal protection in and out of the water.
- Autumn: Bring a UPF rash guard to protect from the sun instead of sunscreen.
- Winter: Pack a 3mm or 5mm wetsuit, plus a windbreaker or light jacket for the boat ride back.
- Year-round: Bring cash for the roughly 125 MXN park fee, a reusable water bottle, and a dry bag.
Do tours operate all year?
Yes, guided snorkeling and diving tours run daily throughout the year.
The park is open daily from 8:00 AM to 6:00 PM. Most tours take 6 to 8 hours round-trip from Cabo San Lucas or San José del Cabo. Since weather can cause cancellations, book early in your trip.
