The Best Time To Swim With Humpback Whales
The best time to swim with humpback whales in Tonga is any time during whale season — otherwise, the whales are simply just not there!
Expect 1-3 amazing days on a 5 swim day tour, and 4-6 amazing days on an 8 swim day tour.
Watch our 5 Day Swim video below, to get a sense of what a 5 swim day trip could look like.
The whales arrive from Antarctica toward the end of June, and we begin swimming with them in mid-July through to the first week of November.
We have never had a group not swim with whales in over 20 years.
July / August: Newborn calves, mating behavior, heat runs, and very interactive males.
September / October: Predominantly mom-and-calf encounters, with beautiful, intimate interactions.
October is our favorite month, as we typically experience calmer seas, warmer weather, and some of the most interactive calves of the season — making for incredibly special in-water encounters.
Rather than focusing on the “best” month, it’s more important to think about your time on the water. The more days you spend out there, the greater your chances of having truly memorable and meaningful encounters.
We see and swim with whales almost every day, but our focus is always on quality over quantity — not just quick sightings. Our experienced guides and captains know exactly when and where to place you in the water to maximize these moments.
To us, a quality encounter means close proximity and a minimum of around 10 minutes in the water. Of course, this is nature — sometimes encounters are even longer and more extraordinary. Every whale and every interaction is completely unique, and ultimately, it’s always up to the whales.
There is no single “best” time to come. While some may suggest otherwise, the reality is that from July through early November, you have a very high probability of incredible encounters weekly, as stated above, we have never had a group not swim with whales in over 20 years!
Since not all females give birth at the same time, we see newborn calves throughout the entire season — we’ve even encountered brand-new babies at the end of October.
Please watch the video below to see what a typical 5 swim day trip can look like.
On average, you can expect 1–3 truly exceptional days on a 5 swim day tour — with other days still offering beautiful and memorable encounters.
