The Lowdown
Alright, Rusty here. Let's have a look at what's coming up for the Robberg area.
Right out of the gate, we’ve got a bit of a slow start, but there's some real quality later on. We’re looking at a solid run of swell, but the winds are going to be a bit of a mixed bag, making it a game of picking the right sessions.
The first real action kicks off on Tuesday morning, the 25th of August. We've got a solid 8ft SW swell rolling in with a very long 14-second period, packing some serious energy (3073) which is strong. It's a bit of a shame about the cross-onshore wind, but the water is sitting at 60°, which is about average for this time of year. The real standout for Tuesday is the afternoon session. That same 8ft SW swell cleans right up with glassy conditions from an easterly breeze. The energy jumps up (3717) and for the experienced crew, this is going to be absolutely firing. This is probably the best bet for the first few days.
Wednesday the 26th looks like a write-off. The swell is still there, but the wind jumps up and turns messy, creating a cross-chop that kills any chance of a good wave.
Thursday the 27th might offer a small window. The morning is glassy again with a 7ft SSW swell. It’s a little smaller, but clean. Not a standout, but a nice little session if you’re keen.
After that, the swell drops right off through the weekend, turning small and weak. We’re looking at a few days of poor to marginal conditions, with wind and chop ruining things. There is a bit of a swell increase on Sunday the 30th, but it's accompanied by rain and onshore winds, so it’s not worth getting excited about.
Now, here’s where it gets interesting. Looking way ahead, around Wednesday the 2nd of September, a proper pulse of swell arrives. We’re talking 15ft from the SW with a 15-second period. The combined energy is massive (7834). The catch? The wind is cross-onshore. It’s going to be big and powerful, definitely only for experts. This one is promising but a long way off, so keep an eye on it.
Then, on Friday the 4th of September, the swell gets even bigger, hitting 23ft from the SE. This is huge, with a combined energy of 13513. The wind is howling, creating choppy and dangerous conditions. This is more of a spectacle than a surf session for most, and it’s a big, powerful, messy beast. This setup would be far more appealing to kite surfers than paddle surfers.
The real gem might be on Tuesday the 8th of September. After that giant pulse eases, we get a 10ft ESE swell, dropping to 8ft in the afternoon, but both the morning and afternoon are glassy. With light or no wind, those waves will be clean and lined up. For the experts, this could be the real payoff after a long wait.
So, to sum it up: Tuesday afternoon the 25th is the first standout. The second, more promising but less certain, is Tuesday the 8th of September for a clean, solid swell. The rest is a mix of wind-affected chop or massive, dangerous surf.
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.
