About this list

Humpback whale seasons differ by country, and even within one country operators give different months. Maptlantis took the 141 operators that name the humpback whale as a target species and state their program season in months, and counted those months as written. The 7 that only say year-round are counted separately. The months most operators name are Jan–Mar, Jun–Oct. The countries with the most operators are Australia (May–Nov), Japan (Jan–Mar), Tonga (Jul–Oct) and Canada (May–Oct). For Tonga, the season stated by a tourism board, research body or local operator is included with its source and check date. 121 of the 140 operators (86%) publish prices on their own channels, so you can compare those directly; ask the rest. Estimated prices are not shown. The months are the operating periods operators state, not a promise that the animals will appear. No wildlife program can guarantee an encounter, and even within the same month it depends on the sea and migration routes.

Humpback whale season by country

The darker a cell, the more of that country's operators name the month as their season. A ringed cell is a month operators single out as the peak. Operators that only say year-round are not counted; their number is shown next to the country. The line under the cells is the season stated by a tourism board, research body or local operator (all twelve cells when year-round); the sources are listed under "Sourced seasons" below.

Sourced humpback whale seasons

Seasons stated by tourism boards, research bodies and local operators. Each entry has a source link and a check date, and none is mixed into the operator counts above. An entry with a region name is a source about that region, so it is not used as the whole country's season.

The Tonga Tourism Authority says humpback whales arrive from Antarctica and mate and give birth in Tongan waters from July to October. Those four months are when you can swim with them.

Frequently asked questions

When is the season for seeing humpback whales?

Combining the seasons of 141 operators, most fall in Jan–Mar, Jun–Oct. The table by country shows how many operators run in each month.

Where is the humpback whale season backed by a source?

Tonga: Jul–Oct (Tonga Tourism Authority). Each entry links to its source with a check date.

Which months are the humpback whale peak season?

Among operators that name a peak, a high season or the most animals, it is Jun–Apr. Few operators say so, so treat it as a guide.

What does a year-round listing mean?

7 operators only say their program runs year-round. That means bookings are taken all year, not that the animals are there all year, so those listings are left out of the monthly count.

If I go in one of these months, will I see humpback whales?

That is not guaranteed. The months are when operators say they run programs; actual sightings vary from year to year with sea conditions, water temperature and migration. Ask the operator about recent sightings before you book.
