June in Indonesia is special because it signals the beginning of the dry season and a fantastic time to see whale sharks. These gentle giants come out to play in the waters, offering a rare chance for people to witness them up close. These gentle marine giants, often called the ocean’s largest fish, migrate into the archipelago’s nutrient-rich waters, particularly in areas like Cenderawasih Bay, Saleh Bay, and Triton Bay. For those embarking aboard the luxurious Mutiara Laut Liveaboard, this month offers a front-row seat to one of the ocean’s most majestic spectacles.
Why June? The Role of Ocean Currents and Plankton Blooms
Whale sharks (Rhincodon typus) are filter feeders that follow the flow of food. As the southeast trade winds blow in June, they stir nutrient-rich currents from the Indian Ocean into Indonesia’s southern waters. This oceanographic phenomenon causes a plankton bloom, drawing in the whale sharks for a seasonal feast.
These currents, known as the Indonesian Throughflow, act as a conveyor belt, channeling calmer waters with nutrients. Areas like Cenderawasih Bay see an influx of zooplankton, krill, and small baitfish—all prime food sources for whale sharks. As such, June becomes a magnet for these elusive creatures.

Fishing Traditions Meet Conservation Science
In places like Saleh Bay in Sumbawa, whale sharks have long been associated with local fishing practices. Traditional fishermen using Bagan nets often encounter these creatures as they hover under fishing platforms, waiting for small fish to escape.
Researchers now collaborate with these communities to tag and track the sharks, revealing patterns that show a consistent spike in sightings during June and July. Data from satellite tags also indicate that whale sharks prefer areas with steady food supplies, calm seas, and limited boat traffic—conditions that align perfectly with early dry season travel.
Mutiara Laut Liveaboard: Combining Luxury and Wildlife Encounters
For travelers seeking both comfort and close encounters with whale sharks, Mutiara Laut Liveaboard offers a balanced experience. This classic two-masted phinisi yacht combines timeless Indonesian craftsmanship with modern amenities. In June, its itineraries are often tailored to regions with higher chances of sightings, ensuring guests don’t just explore Indonesia’s surface beauty but also its incredible marine biodiversity.
Onboard marine biologists and dive guides help interpret the behaviour of these magnificent creatures. Whether snorkelling or diving, guests receive expert briefings on safe and respectful interaction practices, ensuring the well-being of humans and animals.
Ethical Tourism and Conservation Awareness
Swimming with whale sharks isn’t just a travel bucket list item—it’s an opportunity to promote ocean conservation. Mutiara Laut Liveaboard supports responsible tourism by collaborating with local NGOs and marine parks. Guests are educated on the dos and don’ts of marine wildlife interaction, contributing to a deeper understanding of Indonesia’s fragile ecosystems.
The IUCN classifies whale sharks as endangered, making such educational initiatives crucial. Observing them in the wild, especially in a context that supports their protection, adds meaningful value to the travel experience.
Ideal Locations and Itineraries in June
Popular whale shark hotspots in June include:
- Cenderawasih Bay (Papua): Known for its year-round population and close interaction opportunities
- Saleh Bay (Sumbawa): Increasingly popular for predictable sightings due to the bagan fishing platforms
- Triton Bay (West Papua): Part of the Bird’s Head Seascape, rich in biodiversity
Mutiara Laut Liveaboard often includes stops in these regions during its seasonal routes. The yacht’s flexible itinerary allows it to adapt based on real-time marine sightings, weather conditions, and guest preferences.
More Than Just a Swim
Encountering whale sharks aboard the Mutiara Laut Liveaboard in June isn’t merely about checking an item off your adventure list. It’s a rare opportunity to understand the interconnectedness of Indonesia’s marine ecosystems, local cultures, and conservation science. By traveling with awareness and intention, guests contribute to the ongoing effort to protect one of the ocean’s most awe-inspiring species.
Whether you’re a seasoned diver or a curious snorkeler, June is the time to dive in—literally and figuratively—and explore the science, beauty, and responsibility of witnessing the world of whale sharks.
