Southern right whales roll through Eyre Peninsula waters from June to October. Winter is the only season you can pair them with sea lion pups in the water and Coffin Bay oysters at their peak.
On top of that, the national parks are quiet, restaurants are easy to get into, and room rates are the lowest of the year. If you’ve got any flexibility with your travel dates, winter is one of the best times to come to Port Lincoln.

Whale watching
Southern right whales migrate through Eyre Peninsula waters from June to October, and they’re one reason to plan a winter trip. These are big animals – adults can reach 18 metres – and they move slowly and often come close to shore.
From the shore
You don’t need a boat. Sightings are reported from the foreshore in front of Best Western Port Lincoln and from the clifftops inside Lincoln National Park.
Bring binoculars. Southern right whales have a distinctive V-shaped blow you can spot from a distance, and once you’ve got one in view, binoculars let you follow the detail.
Best months: June and July are the most reliable for sightings close to Port Lincoln. The season runs to October, with some years delivering sightings into November.
Sea lion snorkelling with pups
Getting in the water with young sea lions is unlike any other time of year. They’re curious in a way older animals aren’t. They’ll circle you, copy your movements, and swim right up to your mask. Most people come out of the water grinning.
Pupping seasons vary by colony, so ask your operator what to expect for your travel dates.
What to expect. Charter operators run guided snorkelling tours from Port Lincoln’s waterfront out to sea lion colonies. Full wetsuits are provided. The water sits around 14 to 16°C, which is cold, but once you’re in you stop thinking about it quickly.
Who can join. Most operators suggest ages 8 and up with basic swimming ability. Check before booking, as requirements vary.
For the full rundown of wildlife experiences, see our Wildlife encounters in Port Lincoln guide. It covers operators, timing, and what to expect on each tour.
Shark cage diving
Shark cage diving at the Neptune Islands runs all year, but winter has one advantage: clearer water. Cooler months bring better visibility, so you can see the sharks from further away and the view from the cage is sharper.
Tours leave from Port Lincoln and take around three to four hours to reach the islands. No scuba certification is needed for the surface cage. See our article about shark cage diving for a rundown of this once-in-a-lifetime experience.
Wildflower walks in the national parks
Late winter into early spring is wildflower season on the Eyre Peninsula, and both Lincoln National Park and Coffin Bay National Park put on a good show.
Lincoln National Park. About 30 minutes south of Port Lincoln. From late July the coastal trails pass banks of everlastings, orchids, and flowering native shrubs. Kangaroos and emus are out in the mornings, and on a winter weekday you can walk for hours without running into anyone.
Coffin Bay National Park. 45 minutes north-west. Just as good for wildflowers, and you can pair a morning walk with an oyster lunch in town. The Yangie Bay loop is around 5 km return, suits most fitness levels, and passes through dunes and coastal bush with good wildlife along the way.
Our Coffin Bay National Park guide covers the walking tracks, entry requirements, and how to plan the day trip.
Coffin Bay oysters at their best
Coffin Bay oysters are good any time of year, but winter is when they peak. Cold water produces a firmer texture and a cleaner flavour. If you haven’t tried them before, this is the time.
A winter day trip to Coffin Bay works well: the national park is quiet, the drive is easy, and the oyster farm experiences and in-town venues all operate through winter. Get there before midday for the best choice of fresh options.
Winter fishing
Winter is a solid time to fish around Port Lincoln. Cooler water brings King George whiting and garfish into the shallower bays, and locals will tell you the foreshore fishing picks up from May.
No boat needed – fish from the Yacht Club jetty or the town pier. A few things to know:
- You don’t need a licence for recreational fishing in South Australia
- Bag and size limits apply, and snapper is fully closed in these waters [CHECK: closure runs to 30 June 2027 – confirm before publishing]. Check the PIRSA website for current rules.
- Local tackle shops can point you to the best current spots and bait
Eating out in winter
Port Lincoln’s restaurants and pubs are more relaxed in winter. You can walk into most venues without waiting, take your time over a meal, and get a table with a water view most nights of the week. The seafood is the same quality as summer. The pace is slower and easier to enjoy.
Our Local food and wine guide covers the best dining in Port Lincoln and across the Eyre Peninsula.
What to pack
- A windproof and waterproof outer layer, essential for boat tours and coastal walks
- A warm mid-layer for mornings and evenings
- Waterproof walking shoes for national park tracks
- A warm hat for early morning wildlife watching
- Binoculars for whale watching from shore or boat
