Whale Migration on the Central Coast: How Humpbacks Navigate North
Every year, the breathtaking spectacle of humpback whales migrating along the east coast of Australia draws nature lovers to the water. From May to July, thousands of these magnificent creatures embark on their journey north, leaving the icy waters of Antarctica for the warm breeding grounds of the Great Barrier Reef. But have you ever wondered how they manage to swim against the powerful ocean currents? Their secret lies in a clever navigational strategy that helps them avoid the strong East Australian Current (EAC) and conserve energy along the way.
How Do Whales Avoid the Currents?
The East Australian Current (EAC) is a warm, fast-moving ocean current that flows southward along the east coast of Australia, from the Great Barrier Reef down to Tasmania. If whales were to swim directly north against it, they’d expend enormous amounts of energy. Instead, they take a smarter route.
Rather than fighting the current, humpbacks stay close to the coastline where the waters are shallower and the influence of the EAC is weaker. This allows them to migrate more efficiently, conserving their energy for what matters most—breeding, giving birth, and caring for their young.
Why Do Whales Migrate?
Humpback whales undertake this long journey for a crucial reason: to give birth in warm, sheltered waters where their calves can thrive.
Northbound Migration (May–July): Pregnant females, along with other adult whales, travel north to the Great Barrier Reef and the Coral Sea, where warm waters provide a safer environment for birthing and nurturing newborn calves.
Southbound Migration (August–November): Once the calves are strong enough, the whales begin their return journey to the Antarctic feeding grounds, where they replenish their energy for the next migration cycle. During this phase, they often swim further offshore, as the calves are now better prepared for open water.
Whale Watching on the Central Coast
For those hoping to witness this awe-inspiring migration, the Central Coast offers prime whale-watching opportunities. The best time to see humpbacks traveling north is from June to early August, when they pass close to the coastline. During this time, it’s common to see them breaching, tail-slapping, and playing in the water as they journey past.
