Everything you need to know about the whale watching season in perth

Whale watching on Australia’s west coast is a remarkable experience, thanks to its long, life-rich shoreline and sheltered bays that serve as prime feeding grounds. Perth lies directly along the famous Humpback Highway, the migration route followed by thousands of whales as they travel to and from warmer breeding waters. 

While Humpback sightings are common, you might even spot the elusive Blue Whale at the Perth Canyon, a deep-sea feeding hotspot just offshore. If whale watching is on your bucket list, this guide will help you understand the season and plan your trip for the best chance to witness these ocean giants up close.

When does whale watching season start and end in Perth?

Whale activity along the Western Australian coast stretches across much of the year, but Perth’s primary whale watching season typically runs from September to early December. This is when Humpback Whale mothers and their newborn calves migrate south from the breeding grounds in the Kimberley region back to the nutrient-rich waters of Antarctica. During this return journey, the whales swim closer to the coast especially near Rottnest Island and Perth's shoreline making it an ideal time for spectacular sightings. 

The northbound migration happens earlier in the year and is no less impressive. From late May to mid-July, Humpback Whales travel northwards past Perth on their way to the warmer calving grounds in the Kimberley. While this leg of the journey is often more direct and offshore, it’s still possible to see whales during this time—particularly adult pods and competitive males moving at speed. Perth-based sightings during the northbound phase tend to be more sporadic, though Augusta’s Flinders Bay, just a few hours south of Perth, offers excellent whale watching from May through July.

Best time to see whales in Perth

Northbound Migration (late May – Mid-July)

What you'll see:
Adult Humpback Whales often pregnant females heading north to the Kimberley breeding grounds. Pods during this period are usually swift and directional, with high-energy behaviors like breaches, tail slaps, and fluke dives seen further offshore. Sightings are less predictable but still possible on clear days, especially near deeper waters like those around Rottnest Island.

Why late May–mid-July is worth it:

  • It’s early in the annual migration cycle, offering the first chance to spot whales heading up the coast.
  • Calmer winter seas and clear air make for good visibility, especially in the mornings.
  • Some tour operators start trial runs or exploratory cruises during this window.

When to skip:

  • Early May can be hit-or-miss, as the migration hasn’t reached full swing.
  • Perth isn’t the prime northbound destination; try Augusta for better odds during this period.

Southbound Migration (September – Early December)

What you'll see:
Mothers and calves making their way back south toward Antarctic feeding grounds. This is Perth’s peak whale watching season, with whales hugging the coastline and moving slowly. Expect up-close encounters, playful calf behavior, breaches, tail lobs, and even curious approaches toward tour boats.

Why September–November is ideal:

  • Sightings are frequent and close to shore, especially around Rottnest Island and Hillarys Boat Harbour.
  • Slower-moving pods mean longer surface time and better photo ops.
  • Many cruises are guided by marine biologists, adding educational value.
  • Weather transitions from cool to mild, offering pleasant conditions for morning and afternoon tours alike.

When to skip:

  • By mid to late December, most whales have passed. Operators wind down, and sightings are not that frequent.

Blue Whale season in Perth

While Humpbacks steal most of the spotlight, Perth also offers a rare opportunity to see Blue Whales, the largest animals on Earth. These ocean giants pass through the Perth Canyon, a deep-sea feeding ground located about 50 km offshore. The season mainly runs between April and May. Sightings aren’t guaranteed and tours are limited, but for wildlife enthusiasts, this is a truly unique chance to witness Blue Whales in their natural feeding habitat, something few places in the world can offer.

Best land‑based whale watching spots in Perth

Rottnest Island – West End Boardwalk

Arguably Perth’s top land-based whale watching spot, West End offers elevated views over deep water where whales frequently pass. From late September to November, it’s common to spot mothers and calves cruising just offshore. Binoculars recommended.

Cottesloe Beach

Famous for sunsets and surf, Cottesloe also offers surprise whale sightings during the southbound migration. Look beyond the breaking waves between October and early December. Early mornings are clearest.

Hillarys Boat Harbour Lookout

Just north of Perth, this accessible lookout offers a panoramic view of the Indian Ocean. It's a great family-friendly option to scan for distant whale spouts or tail slaps in spring.

North Mole Lighthouse, Fremantle

Perched at the edge of the harbor, North Mole offers a front-row view of open water. Bring a windbreaker and camera cause whale sightings are hit-or-miss but stunning when they happen.

City Beach Lookout Point

City Beach provides a scenic, elevated lookout with good vantage points for spotting southbound whales in October and November. It’s also less crowded than Cottesloe and ideal for relaxed coastal viewing.

Cape Peron, Rockingham

Further south, Cape Peron juts into deeper waters, making it a great spot to see migrating whales in early spring. Look for spouts and breaches near the reef break line.

Frequently asked questions about whale watching Perth season

When is the best time to see whales in Perth?

The peak season is September to November, when Humpback mothers and calves migrate south along the coast. Blue Whales are sometimes seen offshore in April and May near the Perth Canyon.

Can I see whales from land or do I need to join a tour?

Yes, you can see whales from land. Spots like Rottnest Island’s West End, City Beach, and Cottesloe offer good vantage points during the southbound migration. However, tours offer closer, guaranteed views.

What kind of whales can I see near Perth?

Humpback Whales are the most common. You may also spot Blue Whales, Southern Right Whales, and occasionally Minke or Sperm Whales during their migrations.

Are whale sightings guaranteed in Perth?

Most tour operators offer high sighting success during peak months. Some even offer “sighting guarantees” i.e., if you don’t see a whale, you get a free return trip.

How far offshore do the whales swim near Perth?

During the southbound migration, whales often swim within a few hundred meters of the shoreline, making for excellent viewing from both land and boat.

What’s the difference between the northbound and southbound migration?

Northbound whales (May–July) move faster and stay further offshore. Southbound whales (September–November), especially mothers with calves, swim slowly and closer to the coast making this the best time for viewing.

Can I see whales on Rottnest Island?

Yes! West End Boardwalk on Rottnest Island is one of Perth’s top whale watching locations during spring. Many visitors spot spouts, breaches, and even calves from land.
