Humpback whale season in Puerto Vallarta
Every winter, North Pacific humpbacks migrate here to mate and give birth. How the federal rules work, small boat vs. catamaran, which pier is closest to your hotel, and the licensed tours you can book.
SEMARNAT sets Puerto Vallarta and Riviera Nayarit's official whale-watching dates every fall — last season ran December 8 to March 23. Peak sightings are January and February when mothers and newborn calves are active. Whales occasionally appear in November or April outside the licensed tour window.
Five real moments from boarding to watching humpbacks responsibly.
Afternoon thermal winds pick up almost every day after 1 p.m. Morning boats cross smoother water and spot vertical blows cleanly before whitecaps form.
Only permitted vessels carry the seasonal whale-watching flag issued under NOM-131-SEMARNAT-2010. Captains communicate over VHF radio to spread boats out responsibly.
Captains scan the bay's deep southern trench and northern shelf for tall mist plumes. When whales surface nearby, engines shift to neutral and stay 60–80 m away.
Federal rules allow up to four boats at a time per whale pod for at most 30 minutes before rotating out so mothers and calves can rest.
Morning crossings feel crisp on open decks. Pack polarized sunglasses, reef-safe sunscreen, motion-sickness pills taken 45 minutes prior, and a dry bag for cameras.
Humpback whale season in Puerto Vallarta
Why thousands of kilometers end right outside Marina Vallarta and Cabo Corrientes.
Pacific humpbacks spend summer feeding heavily off Alaska, British Columbia and California, building fat reserves before fasting on the winter migration south.
Mountain headlands shelter the bay from open Pacific swells while warm coastal shallows give newborn calves calmer water to nurse and build strength.
Male humpbacks sing complex low-frequency melodies audible through onboard hydrophones, while calves practice breaching, tail-lobbing and pectoral slaps.
Enforced by PROFEPA and SEMARNAT: 60 m buffer for small craft, 80 m for larger vessels, 240 m waiting zone, and zero swimming, diving or drones near whales.
Every licensed vessel follows identical distance rules — the real trade-off is height, shade and wave motion.
Agile & fast; minimal shade, rarely a bathroom
Shaded seating, onboard restrooms, snacks/drinks
Custom departure pace & snacks; price is per boat
Same bay, four boarding hubs — pick the closest one so you spend less time in taxis.
Largest hub of licensed operators, catamarans, and research boats. Note there is typically a small federal API maritime port fee collected in cash at check-in.
Convenient for Old Town guests on foot, mainly serving small boats and pangas. Be prepared for a quick step from floating steps onto the boat.
Closest boarding point for Nuevo Vallarta and Flamingos hotels, saving 45+ minutes of highway taxi time and putting boats right near north-bay whale routes.
Full-service marina close to the open mouth of Banderas Bay near Marietas Islands, often fastest into humpback migration lanes.
