When Is the Best Time to See Whales in Augusta?
Planning a trip to Western Australia this winter? Then you won’t want to miss whale watching in Augusta. Each year, the coastal waters of Flinders Bay come alive as migrating whales pass by on their journey north. But when exactly is the best time to see whales in Augusta?
This guide covers the full Augusta whale watching season and everything you can expect on board with Naturaliste Charters.

Whale Season in Augusta: May to August

The whale watching season in Augusta runs from late May through to the end of August. During this time, thousands of whales make their annual migration from Antarctica to the warm northern waters of Australia to breed and give birth.

Augusta is one of the first places in Western Australia where whales arrive each year. That’s why Naturaliste Charters operates daily tours from the Augusta Boat Harbour throughout the season.

Why Whales Visit Flinders Bay

Each winter, humpback whales and southern right whales journey up the West Australian coast. On their way, they often stop to rest in the relatively sheltered waters of Flinders Bay, near Augusta.

These waters give whales a place to socialise, interact, and rest during their long migration. For guests, this means exciting chances to see breaching, tail slapping, and other natural behaviours from close range.

What You’ll See and When

Late May to June marks the start of the season. Humpback whales are usually the first to arrive, and sightings begin early and build quickly.

July is considered peak season. During this time, humpback whale activity is high, with regular sightings of breaching, tail slapping, and other impressive surface behaviour.

In August, some of the humpbacks continue north, but many remain in the region. Southern right whales are more commonly seen later in the season, and the chance of spotting them increases toward the end of August.

Humpback whales with calves are also sometimes observed during the latter part of the season. While conditions in Flinders Bay can vary, August often brings crisp winter mornings and excellent visibility.

Upgrades to the Alison Maree for 2025

Between our Bremer Bay and Augusta seasons, Naturaliste Charters’ 23-metre catamaran, the Alison Maree, is receiving a range of exciting upgrades.

These enhancements are being completed by Robbie Clayton at Niche Marine. They include a 2.5-metre extension to the top deck, a new rear-facing lounge area, and the relocation of life rafts to open up deck space.

Additionally, the flybridge roof is being extended by 4.2 metres. This will allow for a dedicated professional filming and photography platform, meaning media teams and passengers will have more space and clearer viewing access.

Importantly, we are not increasing our passenger capacity. These upgrades are designed purely for greater comfort, more space, and a better viewing experience for everyone on board.

What to Bring on Your Augusta Whale Tour

The weather in Augusta can be fresh, especially on the water. We recommend wearing warm, layered clothing and flat, enclosed shoes.

You should also bring a waterproof jacket, sunscreen, sunglasses, and a camera or phone to capture the moment. Arriving 20 to 30 minutes early will help you settle in before departure.
