The short answer
- Whales pass Byron from May to November. Tours generally run from June. See month by month →
- July is the peak of the northern migration; September the peak of the southern one, with calves. See the two peaks →
- The Cape Byron viewing platform is one of the best places to watch from land. See the lookouts →
Why whales pass Byron
Cape Byron Marine Park is an important habitat for humpbacks. The park’s managers say the whales travel north from their Antarctic feeding grounds between May and July to have their calves in the warm waters of the Coral Sea, around the Great Barrier Reef, and head back south with their young from August to November. Byron is the most easterly point of the mainland, so the migration runs close by.
NSW National Parks put the number at around 40,000 humpbacks a year.

The two peaks
July: the northern migration
Visit NSW calls July the peak whale-watching month, with plenty of high-energy surface activity such as breaching and tail slapping as adults head north.
September: mothers and calves
On the way south, Visit NSW says the whales come closest to shore from August, resting in Byron’s calmer waters with their new calves, and September is the peak of that southern run. Visit NSW also calls August a good month for kayaking with whales. NSW rules mean any boat or paddler must stay 300 metres away when a calf is present.
Small-group whale watching from The Pass
Check your date is inside the season and that everyone meets the age limits of 5 to 70.

What to look for
Visit NSW describes the northern run in July as the time for high-energy surface activity, such as breaching and tail slapping. The Ballina whale-cruise listing adds spy-hopping, when a whale rises vertically to look around. On the southern run, look for a mother with a calf close beside her, often resting in calmer water nearer shore.
Watching from land
The marine park’s managers name three land spots: the Cape Byron viewing platform, which they call one of the best, plus Broken Head and Lennox Head. The Walgun Cape Byron Walking Track reaches the lighthouse; NSW National Parks lists it as a 3.7 km loop and suggests binoculars for whale watching. The lighthouse lawn is open from 8 am to sunset. Parking there is paid by the hour and limited at weekends, so consider walking up from The Pass or Wategos instead. Plan the lighthouse walk.
On the water, by kayak or boat
Three boat tours run in season: a small beach-launched boat from The Pass on GetYourGuide (opens in a new tab), an inflatable from Brunswick Heads and a larger boat from Ballina on GetYourGuide (opens in a new tab) with a toilet on board. The sea kayak tour on GetYourGuide (opens in a new tab) runs all year and, according to its listing, sometimes meets humpbacks from June to October.
How close you can get
NSW rules apply to everyone on the water. Boats, kayaks, surf craft, paddleboards and drones must stay at least 100 metres from a whale, or 300 metres if a calf is present. Jet skis must keep 300 metres from any whale. Swimmers may not enter the water closer than 100 metres to a whale, and once in the water must stay at least 30 metres away. Close encounters happen when a whale chooses to approach.

Questions people ask
What is the best month to see whales in Byron Bay?
July for activity on the northern run; September for mothers and calves closer to shore. June to October gives good odds; May and November are the edges.
Can you see whales in December or January?
Not reliably. The season ends in November. In summer, one tour listing says leopard sharks and manta rays visit Julian Rocks instead.
Is it worth paying for a boat if you can see whales from land?
From land you see blows and breaches at a distance. A boat gets you closer, within the rules, and the guides explain what you are seeing. If budget or seasickness is a concern, start at the lighthouse.
When should I plan the rest of the trip?
