The Lowdown
Alright folks, it’s Rusty here, looking at what’s on the menu for the next couple of weeks. At first glance, this isn’t a clean, easy run. We’ve got a lot of swell but the wind and tide are going to be messing with us for a while. The standout window is a bit further out, but there are a couple of absolutely cracking sessions if you’re patient.
We start off with a bit of a dud. Friday the 7th of August through to Monday the 10th is a write-off. The swell is big, hitting 8ft to 12ft from the SW, but the wind is all over the shop – cross-shore and onshore with rain. The combined energy is massive, reading between 2481 and 3469, but it’s messy and blown out. Not worth paddling out for.
Tuesday the 11th is a slight improvement. The morning shows a cleaner cross-off breeze from the ENE with a 8ft SSW swell, and the combined energy is still a strong 2019. It’s a marginal call, but it’s the best we’ve seen so far. The afternoon gets lumpy again.
Wednesday the 12th looks a bit better on paper. We’ve got a 4ft swell in the morning from the SSW, but the period is a very long 20 seconds. That kind of groundswell can be a bit weird at a beach-and-reef setup like Robberg, tending to close out. The energy is still moderate (1660). By the afternoon, the swell picks up to 5ft with an 18-second period. Still a bit of a cross-shore breeze, so it’s marginal.
Now, Thursday the 13th of August is the first real standout. The morning is looking glassy – that’s a north wind, 3 mph, with clean conditions. The swell is a solid 7ft from the SW at 16 seconds (long period groundswell). The combined energy is a strong 2485. This is a serious session for experienced surfers. The tide will be a factor, but the glassy conditions and that long-period SW groundswell will have some great lines. The afternoon stays clean with a cross-off. This is the one to circle.
Friday the 14th of August morning is also excellent. Offshore wind from the NNW, 6 mph, with a 5ft SW swell at 15 seconds. The energy is strong (1213). This is a more manageable size for a wider range of surfers, and the clean offshore wind is a dream. The afternoon gets a bit light and cross-on, so get out early.
The weekend of the 15th and 16th of August is a mixed bag. Saturday the 15th morning is clean with a 4ft SW swell, but by the afternoon it’s glassy again with a 6ft SW swell at 16 seconds. That’s a solid, clean afternoon session. Sunday the 16th is tiny, with only 2ft to 2ft, not worth worrying about.
Monday the 17th of August sees another fantastic window. The morning is glassy, absolutely glassy, with a 6ft SW swell at 14 seconds. The combined energy is a strong 1509. The afternoon is even better – absolute calm, zero wind, with the same solid 6ft SW swell. This is a high-quality session for the experienced crew.
The following week starts to fade. Tuesday the 18th through Thursday the 20th is mostly marginal or poor, with lighter swells and increasing cross-chop. The energy drops to moderate levels (around 607 to 1420). Not great.
But then, Friday the 21st of August and Saturday the 22nd bring a late run. Friday morning has a clean cross-off breeze with a 6ft SW swell (energy 1121). Saturday the 22nd morning is glassy again with a 6ft SSW swell, energy 896, and the forecast says “expect very good surf conditions.” That’s a nice way to end the run.
So, to sum it up: the first four days are a bust. The real action is on Thursday the 13th and Friday the 14th of August, with Monday the 17th also a top-tier day. The long-range Saturday the 22nd of August is a promising, clean finish. For the best of the best, I’d be looking at Thursday the 13th morning – that glassy, 7ft, long-period SW groundswell at Robberg is going to be something special. Get in the water.
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.
