The Lowdown
G’day folks, Rusty here. Let’s have a look at the outlook for Robberg. It’s a bit of a mixed bag over the next couple of weeks, but there are a couple of moments that’ll get the heart pumping, so let’s get into it.
Right off the bat, we’re looking at Wednesday the 2nd with a solid 9.8ft SW swell rolling in at 13 seconds and a massive 3127 combined energy. But don’t get too excited—the wind is a light cross-onshore from the SE, so it’s gonna be a bit bumpy. The water temp is 59.5°, which is 3.9° colder than normal, so you’ll want at least a 4/3 wetsuit; it’s much colder than you’d expect for this time of year. The wave comment says “marginal” and honestly, it’s a big, chunky swell but the conditions aren’t making it pretty. This is a beach and reef setup, so with that size, it’s genuinely only for experienced surfers—8ft and over is expert territory.
Thursday the 3rd is a write-off. The morning drops to 5.6ft SW, but by the afternoon heavy rain and a 25 mph SSE wind turn it into a complete mess. Don’t even bother.
Friday the 4th and Saturday the 5th stay poor. The wind is strong cross-shore, the swell is all over the place with short periods, and the conditions are lumpy and choppy. This is the kind of setup that’d be more interesting for kite surfing than paddle surfing.
Sunday the 6th is a weird one. We’ve got a 4.9ft SSW swell but with a 20-second period—that’s a very long period groundswell. The combined energy is 2614, so there’s plenty of grunt. That long period will be better for a point or reef than a beach break. Wind is a moderate cross-shore from the east, so clean it ain’t. The afternoon bumps up to 7.9ft with an 18-second period and 4638 energy, but still that same cross-shore wind messing it up. It’s marginal, not worth paddling out unless you’re desperate.
Monday the 7th sees an improvement on the wind front. Morning has a light cross-onshore from the SW and 5.6ft SSW swell at 14 seconds. It’s still just “light cross-onshore with small wind ripples”—not perfect, but workable. The afternoon turns cross-shore, so it’s still a bit lumpy. Probably a session for the committed.
Now, here’s a little bright spot. Tuesday the 8th: morning glass-off with a 3.6ft SW swell at 12 seconds. The wind is onshore from the south at only 3 mph, but the state is “unknown” which means it’s likely clean. The afternoon is glassy from the SE at 3 mph with a light cross-onshore ripple. Small waves, but clean. Worth a paddle if you’re keen on something mellow.
Wednesday the 9th is another glassy moment in the afternoon. The swell is only 2.6ft SW at 13 seconds with 248 energy—weak, but “glassy” conditions means a longboard or a foamie would be a joy. The water is still cold, so don’t forget the booties.
Thursday the 10th is probably the best of the first week. The afternoon has 5.2ft SW swell, 11-second period, and glassy conditions from the east at 3 mph. The wave comment says “very good surf conditions.” That’s the one to circle. Clean lines, manageable size, and the period is solid enough to hold together.
From Friday the 11th through to the end of the first week, it’s a mixed story of medium swells and messy winds. Nothing to write home about.
Now, let’s look at the second week.
Saturday the 12th and Sunday the 13th bring a big pulse of east-southeast swell. Saturday afternoon hits 11.5ft at 8 seconds with 1805 energy. That’s a short-period windswell, so it’ll be fat and bumpy. With strong cross-shore winds, it’s poor. Sunday gets even bigger at 13.1ft east-southeast at 9 seconds with 2808 energy—same story, lumpy and nasty. Not for beginners.
Monday the 14th is a slight relief. Morning has 7.5ft east-southeast at 10 seconds with a clean cross

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.
