Every winter, humpback whales migrate from the cold feeding grounds of the north to the warm, sheltered waters of Banderas Bay to mate, give birth and nurse their calves. The season is generally December through March, with the bay's operators saying it officially starts in December, so on 5 November 2026 whales are only beginning to arrive and tours are not yet in full swing. Book for dates from early December, and aim for January or February when sightings are most reliable. The small-group tour we link is rated 4.7 from 190 reviews, leaves at 7:30 in the morning, lasts about three hours, carries up to thirty guests, and includes hotel pickup, hydrophones to hear the whale songs, a light snack, bottled water and the entry and conservation fees listed on the booking page. Expect to see tail slaps, breaches and mothers with calves, though wildlife sightings are never guaranteed, and boats must keep a respectful distance under local rules.
Reading the season: whales begin arriving in late November and December, numbers build through January and February, and most have left for Alaska by around March. If you are visiting now, book a December date rather than assuming a November trip, and ask the operator when their season opens. Spotting is possible from shore and from hotel rooftops, and some properties, such as Hacienda San Ángel, even mention watching whales from their bell tower. A boat gets you much closer, with an expert guide and a hydrophone to listen to the songs.
Choosing a tour: you will find small groups, larger catamarans with meals, private charters and combined whale-and-snorkel trips. Smaller boats are easier to maneuver around the animals and are more personal, but sea conditions can make them bumpier. Larger boats offer more stability, food and drinks. Look for operators who follow the distance rules, never chase the whales and keep their engines at low speed near the animals. A biologist or trained guide adds value to the commentary.
What to bring: layers for a cool and breezy early morning, a windproof jacket, sun cream, sunglasses, a hat and a camera with a zoom lens. If you are prone to seasickness, take medicine beforehand, as the bay can be choppy. Be prepared to pay a small conservation fee at check-in if it is not included. Tours that find no whales usually offer a repeat trip or partial refund, so read the guarantee terms before you book.
