The Lowdown
Alright, let’s talk about Robberg. This is a beach and reef setup, and it’s a spot that’s pretty inconsistent—so when it comes alive, you’ve got to be ready to go. The water is sitting at 57°, which is a full 7° colder than normal for this time of year. That’s a serious bite, so you’re going to need a thick suit, booties, gloves, the whole deal.
The first few days are a bit of a struggle. Saturday the 22nd and Sunday the 23rd are a messy mix of cross-shore winds and lumpy chop. The swell is there, about 6ft to 8ft from the SW, but it’s just not clean. You’re fighting the wind. Monday the 24th is more of the same; light cross-onshore breezes keep things bumpy. The wave energy is moderate, but it’s not translating into good waves.
Now, here’s the good stuff. Tuesday morning the 25th is a real standout. The wind goes glassy, dead calm, and the swell hits 8ft from the SW with a very long period of 14 seconds. That’s proper groundswell. The combined energy is strong. This is a big, powerful swell, so it’s strictly for experienced surfers only—over 8ft is expert territory. For a point or reef break, that long period will set up some beautiful, long lines. The morning is the session.
Wednesday the 26th and Thursday the 27th are a mixed bag. Wednesday gets hammered by a fresh cross-shore breeze, chopping it up. But Thursday afternoon, the wind drops to glassy again with a 6ft SSW swell. That’s a much more manageable size, and the energy is still solid. Another excellent window for the experienced crew.
Friday the 28th is a sneaky good day. The morning is marginal, but the afternoon brings a clean, cross-offshore wind with a 5ft S swell. That’s clean, shoulder-high waves with a light breeze grooming them. A good option for a wider range of surfers.
Saturday the 29th is a wild card. The morning is a strong offshore—25 mph from the NNW—but the swell is tiny at 3ft, so it’s a paddling nightmare. The afternoon, however, is a beast. An 12ft SW swell rolls in, with very strong energy. The wind is a light cross-offshore, making it clean. This is huge, powerful, and for experts only. It’s a standout for sheer size.
From the 30th of August through the 1st of September, the swell hangs around the 5ft to 8ft mark, but the wind is mostly cross-shore or cross-onshore, keeping the quality just okay. There are some windows, but nothing to get too excited about.
Now, look ahead to the 3rd of September. That Thursday morning sees a massive 12ft SW swell with a period of 16 seconds—that’s about as long as it gets. The wave energy is huge. The wind is calm, but there’s a tiny bit of ripple. This is a long-range standout, promising but a bit less certain. If it comes together, it’ll be an absolute monster of a day for the experts. Then Sunday the 6th of September, the wind goes glassy again with a 10ft SW swell and strong energy. That’s another excellent session for the experienced surfer.
Overall, Robberg rewards patience. The best bet is Tuesday morning the 25th for that glassy, long-period groundswell. And if you’re an expert, circle the 3rd of September as a potential date with a big, clean swell. The weekends in between are mostly a washout or too big for the average punter.

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.
