Whale Shark Season in La Paz: Everything You Need to Know
La Paz is one of the most reliable places on earth to snorkel alongside whale sharks — the largest fish in the ocean, and utterly harmless. Each winter, juveniles gather in the bay's protected refuge zone to feed, and licensed operators take small groups out to swim with them. Here is exactly when to come, what it costs, and how to do it right.
The Season, Month by Month
The official whale shark season in La Paz runs October 1 to April 30. Operators need enough sharks reliably present in the swimming zone before tours begin, so the opening date shifts each year.
Opens ~Oct 1 when enough sharks arrive. Fewer boats, variable numbers.
Numbers building. Good value before peak-season prices.
Highest numbers, most consistent tours. Book ahead — busiest window.
Closes ~Apr 30. Sharks thinning out; still possible early in the month.
No whale shark tours. The sharks have moved on and the zone is out of season.

The Rules That Protect the Sharks
The refuge zone is regulated by SEMARNAT. Following the rules is not optional — it is why the sharks keep returning:
- Snorkeling only — no scuba, no free-diving down to the sharks
- No touching, chasing, or blocking a shark's path
- A capped number of swimmers per shark, and licensed guides only
- Reef-safe sunscreen only (zinc oxide or titanium dioxide) — chemical sunscreens are banned
- Minimum distance maintained at all times
Frequently Asked Questions
When is whale shark season in La Paz?
The official season runs October 1 to April 30. It opens only once operators consistently find enough whale sharks in the protected swimming zone, so the exact start slides year to year. December through March is peak — highest numbers and the most consistent tours. Tours are closed May through September.
Are whale shark sightings guaranteed?
No. Whale sharks are wild animals and numbers vary daily and seasonally. Recent seasons have been unpredictable. Reputable operators will reschedule or refund if conditions are poor, and many now confirm shark presence on the water before finalizing payment. Book a tour early in your trip so you have a spare day if it gets pushed.
How much does a whale shark tour cost?
Roughly $80–$130 USD for a standard shared group tour, $150–$180 for a combo tour that adds a second stop, and $200–$300+ for a private or premium boat. Prices rise during the December–March peak. Most tours include snorkel gear, water, and a conservation bracelet.
Is it safe and ethical to swim with whale sharks?
Whale sharks are filter feeders — completely harmless to humans. The activity is snorkeling only (no scuba, no touching) and is regulated by SEMARNAT: a capped number of swimmers per shark, minimum distances, no sunscreen chemicals in the water, and licensed guides only. Choose a permitted operator, wear reef-safe (zinc/titanium) sunscreen, and follow the guide.
