Western Australia's southwest coast becomes a migration corridor twice each year as humpback and southern right whales travel between Antarctic feeding grounds and tropical breeding waters. Busselton sits directly along this route, with Geographe Bay offering sheltered waters where whales pause, breach, and nurse calves within sight of the famous timber jetty.
Quick answer
The whale watching season in Western Australia runs from mid-May through late October, with peak sightings in Busselton occurring between June and September. Humpback whales pass northward from May to July during their migration to breeding grounds, then return southward with newborn calves from August through October. Southern right whales appear less predictably but favor Geographe Bay's calm waters during winter months, particularly July and August.
More than 35,000 humpback whales migrate along Western Australia's coast each year, making it one of the largest documented cetacean movements on Earth. The species was hunted to near-extinction by the 1960s, with fewer than 500 individuals remaining in the eastern Indian Ocean population, but strict protections have allowed numbers to recover at roughly 10 percent annually since the late 1970s. Busselton's position on the inner curve of Geographe Bay creates natural shelter from Southern Ocean swells, drawing whales that seek respite during their multi-thousand-kilometer journey. Mothers with young calves use the bay as a rest stop, staying for days rather than hours while teaching newborns to breach and slap their tails against the surface. The Busselton Jetty, extending 1.8 kilometers into the bay, offers an elevated vantage point where observers can spot blows and dorsal fins without leaving shore. Early mornings between 8:00 and 10:00 typically yield the clearest sightings, when winds are light and the ocean surface reflects less glare. Southern right whales follow a less predictable pattern but appear in Geographe Bay most winters, especially when calving. These slow-moving baleen whales stay closer to shore than humpbacks and can be identified by their stocky bodies, lack of dorsal fin, and distinctive callosities—rough white patches of skin on their heads. When conditions align, both species may be visible simultaneously during the transition months of late July and early August, when northbound stragglers overlap with the first returning mothers. Water temperature, krill abundance in Antarctic waters, and prevailing currents all influence exact arrival dates, which can shift by two to three weeks between years. Observers planning visits around the migration should target the core winter months when whale presence is most consistent, understanding that sightings are never guaranteed but statistically probable during the established season. The jetty remains accessible year-round, with the 5 AUD day pass covering entry from dawn to dusk regardless of marine activity offshore.

Check the local marine forecast for low wind speeds, as calm water significantly improves visibility for surface-active marine mammals.
Bring binoculars with 8x or 10x magnification, as higher power settings are often difficult to stabilize against the movement of the jetty.
