The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Robberg zone. We’re dealing with a beach and reef set-up that’s a bit of a moody character – it’s inconsistent, so you’ve gotta pick your moments. The water’s sitting at 61°F, which is about a couple degrees cooler than normal for this time of year, so grab a decent spring suit.
The first real chance to get wet comes on Tuesday the 11th of August, but I wouldn’t rush. The afternoon sees a 6ft SSW swell rolling in with a 12-second period, but that cross-shore wind from the east at 19 mph is going to make a mess of it. The combined energy is a solid 1611, but the conditions are just too lumpy. Wednesday the 12th is much the same story – a bit of swell around but cross-shore winds keep it ugly.
Thursday the 13th morning is where things perk up. The swell drops to 4ft from the SSW, but the period stretches out to a long 19 seconds. That’s proper groundswell energy. The wind turns cross-offshore from the ENE at just 9 mph, and the water cleans right up. The combined energy is a strong 2738, which is plenty of push. This is a standout session for the intermediate crew – long-period groundswell at a reef tends to line up nicely, but watch for the sets to be a bit spread out. Crowds are a possibility here, so expect some company.
Friday the 14th is another winner. Morning and afternoon both hold clean conditions with light cross-off breezes. The swell sits around 5ft to 5ft from the SW, with periods dropping but still decent at 15-16 seconds. The energy is moderate to strong (1200-1528). This is the best back-to-back window of the whole outlook. Excellent for experienced surfers.
Saturday the 15th and Sunday the 16th fizzle out. Swell drops right off, and the wind goes onshore or cross-shore with very little energy left (139-855). Not worth paddling for.
Monday the 17th brings a pulse back – 6ft SW swell with a 13-second period, energy around 1418. The wind is light, but it’s a cross-on or cross-shore, so the surface is a little rippled. It’s a marginal call.
Then we hit a bit of a dead zone from Tuesday the 18th through to early Wednesday the 19th. Small, weak, and messy.
Now, the real headline act is Wednesday the 19th of August, morning. We’ve got a 10ft SW swell, period 11 seconds, and the wind goes glassy – absolute zero from the ESE. The combined energy is 1976. That’s a powerful swell, but at 10ft, this is for experts only. If you’ve got the skill, this is a session to remember. Thursday the 20th morning is also glassy with a 6ft SW swell (1114 energy), a perfect follow-up for the slightly smaller crowd.
The last week of the window is a mixed bag of moderate swells and cross-shore winds. The standout in the deeper end of the forecast is Wednesday the 26th of August, afternoon. A 8ft SSW swell, period 12 seconds, and glassy conditions from the SSE. The combined energy is 1684, and it’s marked as excellent for experienced surfers. That’s a promising long-range call, but it’s a ways out, so keep an eye on it.
Overall, the best bets are Thursday the 13th morning, Friday the 14th, and the glassy morning of Wednesday the 19th for the brave. The 26th afternoon is one to circle on the calendar.
Rusty out.

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.
