Whale Watching season in Jervis Bay | Best time to spot humpbacks

Every year from May to November, the east coast of Australia turns into a blue highway and guess who is the traffic? Thousands of humpback whales on the move. It’s migration season, and if you time it right, you can watch these ocean giants cruise right past the shores of New South Wales. While hotspots like Sydney and the Gold Coast steal the spotlight, Jervis Bay keeps things low-key. It's quieter, more serene, and just that bit more magical. In this guide, we’ll walk you through when to go, why it’s special, and what the whale watching season in Jervis Bay is like.

When does whale-watching season start and end in Jervis Bay?

Jervis Bay sits smack on Australia’s famous “Humpback Highway,” where thousands of  humpback whales make their annual journey along the east coast. Here’s the lowdown:

Northern migration: May to Mid‑August

  • Whales begin their northward journey from Antarctic feeding grounds toward Queensland’s breeding areas.
  • In Jervis Bay, they often cruise just off the dramatic sea cliffs, moving steadily at around 4–9 km/h. 
  • Peak activity typically hits in June and July, when pods including pregnant females pass through in good numbers.

Southern Migration: Late August to November

  • The whales make their return south, this time often with calves in tow.
  • From October to November, many mother–calf pairs stop in the bay’s sheltered, shallow waters to rest and nurse.
  • This leg of the journey is quieter and more intimate. This is when you might get an opportunity for close encounters as whales swim near boats or shorelines.
  • These calmer waters provide an ideal backdrop for observing behavior like spy‑hopping and social bonding.

Why whales love Jervis Bay

Best time to go on a whale-watching tour in Jervis Bay

If you’re chasing whales, June to August is prime time in Jervis Bay. That’s when Northern and Southern migrations overlap, flooding the bay with humpbacks.

When it comes to time of day, morning cruises (10am slot) have calmer seas and softer lighting. This is best for photos and spotting activity early. Afternoon tours are more relaxed but tend to be windy.

Avoid booking in May or November if you're after consistent sightings: those are transition months with fewer whales passing through and choppy seas can crop up.

Frequently asked questions on Jervis Bay Whale-Watching Season

When do the whale-watching tours actually start and stop in Jervis Bay?

The seasonal cruises typically operate from early May through late November, syncing with the annual humpback migration. Operators begin scheduling regular departures as soon as the first northbound sightings occur, usually in the first or second week of May.

How far in advance should I book a whale-watching tour?

For peak months like June and July, it’s smart to book at least 1–2 weeks ahead, especially for weekend slots. These months see high visitor interest, and Jervis Bay's smaller group sizes mean tours fill quickly.

Are tours available every day during the season?

Most tours run daily, weather permitting. However, cruises may be cancelled or rescheduled during rough sea conditions or high winds, especially in shoulder months like May or late November. Always check your email or phone for updates the day before departure.

What’s the best tour time for sightings—morning or afternoon?

Morning departures (around 10 am) tend to offer calmer seas and better visibility, increasing your chances of spotting a breach or blow. Afternoon tours (1pm) are still rewarding but might get choppier depending on the day’s weather.

Will I see whales if I go in May or November?

You might, but your odds improve in mid-June to early October. May is when whales begin their migration north, and November is when they wrap up their journey south meaning sightings are more sporadic, and tours may not run daily in those months.

Is there a guarantee for whale sightings during the season?

Yes, some tours offer a “sighting guarantee”. If no whales are seen, you may be given a free return cruise or discounted rebooking, depending on availability. Be sure to check the fine print when booking.
