Whale watching season in Sydney 2025: When to go, where to watch & what to expect

Every winter, Sydney transforms into a stage for one of the ocean’s most interesting phenomena. From mid-May to November, humpback whales migrate past the city’s coast, sometimes so close that you can spot them right from the shore. The real drama unfolds in June and July, when whale traffic peaks and breaches can number in the dozens each day.

Whether you're perched on a sandstone cliff or cruising through sapphire waters, there’s nothing quite like the moment a 40-tonne whale launches into the sky. It's raw, unscripted, and quite thrilling if you ask me. If you are keen on watching this spectacle then read this article to know more about the whale watching season in Sydney.

Why whales visit Sydney’s coast every year

Each year, an estimated 40,000 humpback whales travel from Antarctica to the warmer breeding grounds off Queensland, and Sydney lies directly along their migratory superhighway.

Northbound (May–August)

This is the courtship leg of the journey, when male humpbacks put on powerful displays to attract mates. Expect thunderous tail slaps, chest beating with pectoral fins, and dramatic breaches sometimes in rapid succession as they compete for attention and dominance within the pod.

Southbound (August–November)

Mothers return from the tropics with newborn calves in tow, sticking close to the shoreline where the waters are calmer and safer from predators. Their slow, synchronized movements and tender interactions offer some of the most intimate and heartwarming moments of the season.

Whale migration is driven by instinct, survival, and the steady rhythm of the seasons. Like humans, humpbacks travel in family pods, form lasting bonds, and even show signs of empathy. Remember the whale scenes in Avatar: The Way of Water? This is your chance to see something like that up close.

Sydney whale watching season, month by month

May – June (Season begins: northbound migration)

This is the start of the whale watching season in Sydney. Humpbacks begin their long swim from Antarctic feeding grounds to the warmer waters of Queensland. By late June, expect dozens, sometimes hundreds of daily sightings if the weather is good. Look for breaches and tail slaps, signs of whales competing for mates as they move north.

June – July (Peak season: heavy northbound traffic)

This is prime whale watching time. The migration is in full swing, and Sydney’s coastal cliffs and tour boats become some of the best places in the world to spot humpbacks. Nearly every vessel sees action, and it’s not uncommon to spot multiple pods from a single lookout. Breeding behaviors like breaching, pectoral slapping, and vocalizations are common.

August – September (Season overlap: both directions

This is a unique time in the Sydney whale season. Some pods are still heading north, while others begin the return south. This mix often leads to “mugging,” where whales, out of curiosity,  circle or hover near boats.

October – November (Season winds down: southbound return with calves)

As the whale watching season draws to a close, mother humpbacks travel slowly with their newborn calves back to Antarctica. These smaller groups often swim closer to shore for safety, making them easier to spot from land. Expect gentler displays like tail lifts, calf spy-hopping, and slow surfacing.

Where to watch: Land or sea?

You’ve got two great options when it comes to spotting whales in Sydney. You can either watch it from one of the city’s many clifftop lookouts, or head out on the water for a closer encounter. Both have their perks, depending on how adventurous (or seasick-prone) you’re feeling.

What to know about Sydney’s 2025 whale watching season

  • Busiest in years: Over 40,000 humpbacks are expected this year. It’s actually part of a comeback story for a species once nearly hunted to extinction.
  • Close encounters: Manly Wharf recently made news when whale pods swam so close they paused ferry traffic. That’s how close you can get.
  • Bonus marine life: Dolphins are seen on roughly 50% of tours. On rare days, you might even glimpse a southern right whale, orca, or a blue whale.
