The Lowdown
Alright folks, Rusty here with a look at the surf ahead for Robberg. We’ve got a bit of a mixed bag coming our way over the next couple of weeks, so let’s get into it.
The week kicks off with a real tease on Tuesday, 15 September. We've got a solid 5ft groundswell rolling in from the east with an 11-second period, and the wind is glassy out of the SSW at just 3 mph. The water is sitting at 58°, which is way colder than normal for this time of year – a whopping 6° below average, so you’ll want a thick suit. The combined swell energy is moderate at 889, but those conditions are prime for a paddle. It’s a clean morning session for intermediate surfers at this beach and reef set-up, though keep in mind that Robberg can be inconsistent.
Tuesday afternoon cleans up nicely too, with a 4ft easterly swell and light cross-offshore winds, but the real standout is that Tuesday morning session. That’s your best bet in the near term.
After that, things get a bit dicey. Wednesday morning the 16th sees a big spike in size with an 8ft SW swell and a 14-second period, but the wind is onshore and the tide conditions look questionable. The combined energy jumps to a strong 3031, but it’s messy. That trend continues through Thursday and Friday with cross-shore winds and lumpy conditions as the size fluctuates between 6ft and 12ft. By Friday afternoon the period drops to 8 seconds from the ESE, turning it into a short-period, wind-affected mess. Honestly, for a few days there, if the wind keeps up, the setup at this beach and reef might be more interesting for kite-surfing than paddling.
There’s a bit of a lull through the middle of the following week with smaller swells and poor winds, but the forecast picks up again towards the end of the month.
The real long-range standout is shaping up for the morning of Sunday, 27 September. We’re looking at a glassy 5ft SW groundswell with a 13-second period, and the wind is dead calm. That’s a superb recipe for clean lines at Robberg. The combined swell energy is a moderate 1468, and it’s calling for excellent surf conditions for experienced surfers. This is a promising one, but being way out there, you’ll want to keep an eye on it as it gets closer.
Prior to that, Friday the 25th morning brings a massive 12ft SW swell with a very strong energy reading of 5203, but the cross-shore wind and marginal conditions mean it’s really only going to be for the experts.
So the bottom line: jump on Tuesday morning this week, and pencil in that Sunday the 27th for a potential gem. The rest of the window is a bit of a fight with the wind and lumpy seas.
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.
