The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at the next couple of weeks. It’s a bit of a slow burner, but there’s some serious juice on the horizon if you’re patient. We’ve got a long window, and it’s definitely a case of picking your moments.
The first few days are going to be a write-off, honestly. Monday and Tuesday are looking pretty ordinary with onshore and cross-shore winds and lumpy, junky waves. The swell’s there, but it’s messy, and you’ll be fighting the chop more than riding it. Not worth the effort.
Things start to settle mid-week. Wednesday the 12th sees the wind ease off, backing off to a cross-offshore direction. The swell drops to around 4ft (with a long 20-second period), and the ocean cleans right up. It’s small, but it’s clean. The energy is still moderate at 1822, so there’s a bit of push behind it. This is a good sign for what’s to come.
Now, here’s where it gets interesting. Thursday the 13th is looking like the first real standout. The swell bumps up to 5ft from the SW, the wind is light and cross-offshore, and conditions are described as excellent. The combined energy jumps to 3756, which is a serious step up in power. This is a solid, clean day with proper chest-to-head high waves. The morning session looks best before the wind picks up a touch in the afternoon.
We get a few more clean days after that. Friday the 14th holds similar size with a light offshore wind in the morning, and Saturday the 15th stays clean but drops off in size to about 4ft. Then Sunday the 16th turns a bit woolly again with a cross-onshore wind and a drop in energy. It’s a bit of a lull.
The following week starts with a bang though. Monday the 17th brings a glassy morning with a 7ft SW swell. The water will be like glass, and the energy is strong at 2607. That’s a big, clean morning. The wind stays light for Tuesday and Wednesday as well, but the swell backs down a touch.
There’s a little more chop mid-week, but then Thursday the 20th has an interesting shift. We get a bit of a lumpy, shorter-period ESE swell, but with clean, offshore winds in the morning. It might be a bit less consistent, but still worth a look.
But the real payday, the one you circle on the calendar, is the final weekend. Look at Sunday the 23rd. A big SSW swell is forecast to build into the afternoon, hitting 12ft with an exceptional energy reading of 5540. The wind is set to be light and cross-offshore, keeping it clean. This is a serious, expert-only swell. We’re talking about big, powerful surf that will light up the reefs and points. This is the one to wait for, the true standout of the whole period. It’s a long way out, so treat it as promising, but the models are loving it right now.
Monday the 24th will still have a strong, clean 8ft swell in the morning, so there’ll be a lot of water moving. And we close out the window on Tuesday the 25th with a glassy 6ft day, a fine way to finish.
For the water temp, we’re looking about average for this time of year, nothing weird going on there.
So, in short, the early week is for the maintainers. Thursday the 13th is your first go-to. But that Sunday the 23rd, that’s the one you want to be free for. That’s a proper West Coast bomb.
Alright, get after it.
Rusty.

Information about the Robberg Surf forecast
The above surf forecast table for Robberg provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Robberg can be found by selecting the local surf guide option on the grey menu. Our Robberg surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Robberg) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Robberg may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Robberg is 6 km (4 miles) from the city of Plettenberg Bay. If you plan a holiday in Garden Route, look for hotels and other accommodation in Plettenberg Bay. Plettenberg Bay has rooms for a wide range of budgets as well as car hire and transport links.
