June to November
Southern right whales come into this bay every winter to calve — close enough in that you watch them from the sand, or from the house with coffee in hand. This footage was filmed by a friend of the house, over the water along this same stretch of the Tergniet coastline. If you are looking for whale-watching accommodation in Mossel Bay, this is the house.
The season
Southern right whales migrate up from the Southern Ocean each winter to calve in the sheltered bays of this coast. The first arrive in late June; the mothers and new calves stay through the spring, with August and September the peak; by mid-November they are gone.
They come remarkably close in. On calm mornings you spot the blows from the beach, and the pairs drift along the back line slowly enough that a whole breakfast can happen around one sighting. No boat required — though Mossel Bay runs licensed whale-watching trips twenty minutes away if you want the close view.

Honestly told
We say it on every page and we will say it here: if you book December expecting whales, you will be disappointed — by then they have gone south again. December belongs to the dolphins.
But if you can travel between June and November, you get the whales, the mildest winter on this coastline — rarely under 10°C — empty beaches, and the house at its cheapest.
The winter arithmetic
Outside the school holidays the house runs at 70% of the December rate — and monthly stays of 28 nights or more take a further 20% off that.
| Whale-season rate | Per night | A whale-season month 28+ nights, 80% of season |
|---|---|---|
| Either unit — top sleeps 5, bottom sleeps 6 | R5 600 | R4 480 / night |
| Whole house — sleeps 11 | R10 150 | R8 120 / night |
Minimum stays outside peak are flexible — ask. R5 600 a night for a whole unit sleeping five, whales included.
The big four
All four swim this stretch of coast, and all four are on this page as they were really filmed — by a friend of the house, with his drone, along the Tergniet coastline within a kilometre of the house. No stock footage. Whales in winter, dolphins through the summer, sharks patrolling the backline — and an orca, caught on camera.
From this bay
Every whale on this page was photographed over the water in front of this stretch of coast. Like everything on this site — no stock images.
