Quick answer
- When: humpback whales winter off Puerto Rico from about December to March, and January–March is the best window.
- Where: the west coast, especially Rincón. The municipality's El Faro park (Punta Higüero lighthouse) is the classic free spot to watch from land.
- How: watch from shore with binoculars, or take a boat charter out of Rincón.
- Rules: NOAA asks everyone to stay at least 100 yards from whales. Feeding or harassing any marine mammal is illegal under federal law, so don't get in the water with whales.
Which whales visit Puerto Rico?
The visitors are humpback whales (Megaptera novaeangliae). North Atlantic humpbacks feed in cold northern waters in summer and fall, then migrate to the West Indies in winter to mate and calve. The Mona Passage off Puerto Rico's west coast is part of that winter range. Adults are roughly 12–16 m (40–52 ft) long, and females are larger than males.
Watch for the spout (a bushy blow), tail flukes lifting before a dive, pectoral-fin slaps and full breaches. Males sing during the breeding season.
When to go
The Municipality of Rincón gives the season as December through March. Most sightings are from January to March. Calm, clear mornings and late afternoons make blows easiest to spot. Sightings are never guaranteed.
Rincón has held a Festival de la Ballena (whale festival) every March since 2004. Check the town's announcements for the dates.
Where to see whales from land
Rincón: El Faro park at Punta Higüero. This park by the lighthouse sits on a point above deep water. It's the best-known free whale-watching spot in Puerto Rico, and the town promotes it for the season. Bring binoculars, arrive early on weekends (parking fills up) and stay for sunset. Rincón is about 2½ hours from San Juan and under an hour from Aguadilla airport. More: Rincón and Rincón beaches.
Elsewhere on the northwest coast. On calm days, people also spot blows from high points between Rincón and Aguadilla. See Aguadilla.
Whale-watching boat tours
Tours run only in season, from about January to March, mostly out of Rincón.
- Dedicated whale charters: some Rincón charter captains sell private whale-watching trips in season. Compare operators in our Rincón tours directory.
- Sailing and snorkel trips: Katarina Sail Charters (Rincón) notes on its site that humpbacks may be spotted on its January–March sails. Treat that as a bonus, not a whale-watching guarantee.
- Ask before you book: whether the trip is whale-specific, how long it is, and whether the captain follows NOAA's 100-yard guideline.
Can you swim with whales in Puerto Rico?
No, and you shouldn't try. Under the federal Marine Mammal Protection Act it's illegal to feed or harass whales, dolphins and other marine mammals. NOAA's viewing guidelines for the Southeast US, Puerto Rico and the US Virgin Islands ask boats and people to stay at least 100 yards from whales (50 yards from dolphins and sea turtles) and never to swim with them. Hawaii and Alaska have a binding 100-yard regulation for humpbacks. In Puerto Rico the distance is a NOAA guideline, but getting close enough to disturb a whale can still count as harassment.
If you see an injured, entangled or stranded whale, report it to NOAA's Southeast hotline (on the NOAA viewing-guidelines sheet) or to the DRNA.
Can you see whales from San Juan?
It happens occasionally, but it's not reliable. The deep water close to shore on the west coast is why Rincón is the place to go.
