Swim with Humpback Whales in Tonga
Stay off-grid on beautiful Uoleva Island and experience one of the world’s most extraordinary wildlife encounters.
Mid July – Early October
We still have limited availability in Mid July and Mid to Late September
Limited Openings in Mid July and Mid–Late September
If you’ve been dreaming of swimming with humpback whales, we currently have a small number of spaces available in:
Mid July
Mid to Late September
These periods are a wonderful time to visit Tonga.
Whale activity is strong, the weather is typically clear and comfortable, and Ha’apai remains peaceful and uncrowded.
Because Sea Change is a boutique eco retreat and our whale swims operate in small groups, availability is always limited — and these remaining spaces are expected to book quickly.
If these dates suit you, we recommend getting in touch soon.
Why Mid July and September Are Special
Peak Whale Season
Humpback whales migrate to Tonga’s warm waters to breed and give birth. Mid season offers excellent opportunities for meaningful encounters.
Beautiful Winter Weather
Tonga’s winter months are often dry, clear, and comfortable — ideal conditions for time on the water and relaxing on the beach.
Fewer Crowds
Ha’apai is naturally quieter than other regions, offering a more personal and authentic whale season experience.
An Intimate Whale Experience in Pristine Ha’apai Waters
Each winter, humpback whales return to Tonga’s warm waters.
From mid July to early October, guests at Sea Change Eco Retreat have the rare opportunity to respectfully swim alongside these magnificent animals in one of the few places in the world where in-water encounters are permitted under regulation.
This is not mass tourism.
We operate small groups, prioritising:
• Quiet, respectful interactions
• Ethical whale practices
• Personalised guiding
• Meaningful time in the water
Every encounter is different. Every moment is unforgettable.
See What Whale Season Looks Like
Swimming beside a humpback whale in clear tropical water is something words struggle to describe. It is powerful, humbling, and deeply moving.
