The Lowdown
Alright, this is Rusty. Let's get into it.
The first week of the outlook is a bit of a mixed bag, but there's a real gem waiting for us if we're patient. The pattern starts with small, clean waves that are worth a look, but the real standout is a massive pulse of energy that arrives around the start of September. After that, the swell sticks around but gets a bit messy with strong winds, so picking the right window is key.
The go-to spot here is Robberg (beach and reef). It's an exposed spot, so it catches everything, but it's inconsistent, so you gotta be ready when it's on. The water is a very chilly 60°F, which is 4° colder than normal for late August – that's "much colder than normal," so a thick wetsuit is a must.
Friday afternoon, August 28th is the first real window. It's tiny, with a 4 ft south swell, but the wind is glassy – dead calm. For a small, exposed break, that's a rare treat. The combined wave energy is moderate (770), and it'll be clean and fun on a log.
Now, the big one. The standout of the entire forecast is Wednesday morning, September 2nd. A massive 13 ft swell from the southwest with a very long period of 16 seconds is forecast. The combined energy is huge (7543). This is a serious groundswell, only for experienced surfers at this size. The wind is a light cross-shore from the east, keeping the lineup manageable. This is the call. The afternoon of the 2nd is still solid with an 12 ft swell, but the wind picks up a touch.
The next true highlight is Saturday morning, September 5th. The swell drops to a still-hefty 10 ft from the east-southeast, but the wind turns light and cross-offshore from the east-northeast. The wave comment says "excellent surf conditions for experienced surfers," and with combined energy of 2039, it's got plenty of punch. Monday morning, September 7th also offers a clean 7 ft east swell with light cross-offshore wind, making for a solid, user-friendly session for the more advanced crew.
The final standout is Saturday afternoon, September 12th. The forecast shows a 15 ft south swell (10 seconds) with glassy conditions. The combined energy is massive (4880), and it's another one for the experts only. It's a long way out, so keep an eye on it, but the potential is there.
For the rest of the time, be aware of a long stretch of marginal conditions. From late Friday the 29th through to the end of the month, the combo of chest-to-head-high swell and onshore or strong cross-shore winds makes for a messy, choppy lineup. The period from Wednesday afternoon, September 3rd, through Friday, September 4th, is a write-off with strong winds and poor surf quality. From Monday afternoon, September 7th, the waves drop off and the consistency falls away, with only small, weak pulses for the second week.
So, the gems are: Wednesday morning, September 2nd for the big-swell crew, and Saturday morning, September 5th and Monday morning, September 7th for cleaner, powerful waves. Don't sleep on that Friday afternoon glass-off either.
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.
