Whale Sharks Near Batangas: When and Where to Look

Whale sharks (Rhincodon typus) are the world's largest fish — reaching up to 12 metres and feeding exclusively on plankton. While Donsol and Oslob in the Philippines are the most publicised whale shark sites, sightings in the Batangas–Quezon corridor are more common than most divers realise, particularly at deeper sites during March–May upwelling season.

Where Sightings Cluster

The most consistent Batangas-area sightings occur at deep sites along the southern Verde Island Passage — particularly at the seamounts between Anilao and Maricaban Island. Kirby's Rock, Cathedral, and the deeper sections of Sombrero Island (a short banca ride east of Anilao) have produced the most documented sightings. Sightings are almost always at depth (20–35 m) rather than at the surface.

Seasonal Patterns

The primary Batangas whale shark season correlates with the Amihan (northeast monsoon) upwelling from January through May. Cold, nutrient-rich water pulled to the surface creates plankton blooms that attract filter feeders. Sightings peak in March and April, with February and May as secondary windows.

Responsible Viewing Guidelines

• Maintain a minimum distance of 3 metres from the body and 4 metres from the tail. No exceptions.
• No touching, riding, or blocking the animal's path.
• No flash photography — turn off your strobe and shoot in ambient light.
• Limit interaction time to 10 minutes per group to minimise disturbance.
• If you encounter a whale shark at Anilao, report it to the dive desk — we log all sightings and share data with the WWF Philippines whale shark monitoring programme.
