Sustainable Whale Encounters

Whilst whale swims and encounters are absolutely incredible - our focus in Mounu is to achieve this sustainably, without adding pressure onto the whales and their migration.

Vava'u, Tonga, faces several challenges when it comes to whale watching, particularly around licensing, increased competition and the sustainability of the industry. Maintaining these licenses requires strict adherence to Tongan whale-watching regulations, which are designed to protect the whales from the stress caused by human interaction, especially during the relatively short whale season from mid-July to October​.

In response to the whale watching issues, we ask you, as tourist to carefully select your guide and act as a advocate for the safety of the whales. Please read below on the safety regulations, what to look for and when to report your experience...

Key guidelines for whale-watching operators in Tonga:

01.

Distance and Approach

  • Maintain a minimum distance of 100 meters (328 feet) from the whales.

  • Approach whales from the side, moving parallel to their direction of travel, and should never approach head-on or from behind.

02.

Swim with Whales Rules

  • Max of 4 swimmers and one guide are allowed in the water at a time with the whales.

  • Maintain a minimum distance of 10 meters (33 feet) from the whales.

  • Swimmers are prohibited from diving beneath the whale or chasing it.

03.

Time Limits

  • Whale-watching encounters are limited to a maximum duration of 90 minutes to reduce stress on the animals.

  • Only two vessels are allowed near a group of whales at any one time to avoid overcrowding.

  • No queuing and hounding whales.

04.

Whale Behavior

  • Operators recognize signs of whale distress or discomfort. If a whale shows signs of stress (e.g., tail slapping, erratic movement, or diving suddenly), the boat or swimmers must leave the area.

  • If there is a mother with a calf, extra caution is required, and interaction times are often shorter!

Why it's important to whale watch responsibly, particularly for species like humpback whales?

Whale watching means entering the whales' world as respectful guests. When a calf wants to feed, or if a whale shows signs of discomfort, it's crucial to give them space by stepping back or exiting the water. Observing their behavior helps us understand when it’s time to respectfully retreat. This mindful approach ensures that our presence doesn’t disturb their natural lives and keeps the experience safe and peaceful for both whales and watchers.

How can individuals distinguish between responsible and irresponsible whale-watching companies when booking a tour in Tonga?

To find a responsible whale-watching company in Tonga, look for operators who prioritize the whales' comfort and approach slowly without forcing interactions. They should respect the whales' behavior, giving space if whales show signs of distress or disinterest. Certifications, environmental partnerships, and positive reviews often signal sustainable practices. Choose companies that focus on conservation and the whales' well-being over tourist demands.

What are the most common ways human activity during whale watching can disturb or harm humpback whales?

Human activity during whale watching can disturb humpback whales by chasing or crowding them, causing stress and behavioral changes. Approaching too quickly or persisting when a whale shows no interest disrupts their natural rhythms. Not every whale wants interaction, and forcing encounters by following or queuing up can harm them. Unsustainable practices by some operators add to this, as they may prioritize tourist demands over the whales' well-being.

What regulations or guidelines exist for keeping a safe distance from whales during a whale-watching tour in Tonga!

In Tonga, guidelines require whale-watching boats to keep a safe distance, usually maintaining at least 100 meters from whales unless the whales choose to approach. Swimmers must follow strict limits, allowing only a few people in the water at once to minimize disturbance. Interaction must be on the whales' terms, meaning no chasing or crowding.
