When to Swim with Whales in Tonga

Humpback whales are not in Tonga’s waters all year round. They migrate from Antarctica each year, arriving in Tonga between June and July in order to mate and calve. They then leave Tonga back for Antarctic waters around October and November, depending on the island group. Because, yes, each island group in Tonga has slightly different whale seasons. We’ll go through them all in this guide to the whale season in Tonga.

Quick Tips for Planning Your Whale Swim in Tonga

  • A successful whale swim is not guaranteed, with different days bringing different results, so book a multi-tour package to increase your chances for a better whale swim
  • When booking a whale tour, make it a day or two later than the date you arrive on the island in case your flight/ferry gets cancelled for bad weather (which happens often)
  • Also allow a day or two after your desired tour date, just in case your tour is cancelled due to unsafe conditions.

The Best Time to Swim with Whales

Now that you know the whale season in Tonga, when is the best time to swim with whales in Tonga? Our 10 Photos That Will Make You Want to Swim with Whales in Tonga Now gives a good insight into how whale behaviours change throughout the season, with some behaviours toward the end of the season making for better whale swimming than those during the beginning of the season.

Early into the whale season, say June and July, whale mothers tend to be more apprehensive about approaching boats while their calves are still newborn, so are more likely to swim away. In contrast, later into the whale season, September and October, calves are older and more inquisitive about swimmers, while mothers are more relaxed, which tends to result in better swims.

However, throughout the season, excitable juveniles playing together and performing “heat runs” are seen in Tonga’s waters, which can be observed at any time during the whale season. You’ll just need to be at the right place at the right time to experience this type of swim.
