The Lowdown
Alright folks, Rusty here. Let's get into it. The coming weeks look a bit of a mixed bag for our local stretch, with some real promise tucked in there, but also plenty of wind to work through. We're hanging out at Robberg, a beach and reef set-up that needs the right conditions to really shine. Water's sitting at a chilly 60°, which is a solid 4° colder than normal for this time of year – so you'll want a good 4/3, no question. The swell energy is strong at 1239 (moderate-strong).
We start this Thursday morning, September 3rd, with a real treat. It's glassy, winds are a whisper from the WSW at 3 mph, and we've got a solid 6ft groundswell from the SW with a lovely 12 second period. The energy's pumping at 1239, and it's going to feel clean and powerful out there. This is excellent, but it's definitely one for the experienced crew – it's got some push. Get on it early because that afternoon it all goes south as a 25 mph SSE cross-onshore rips through, turning things into a choppy, messy 12ft beast. That's a write-off.
Friday the 4th and Saturday the 5th are all cross-shore winds and lumpy conditions, with the swell bouncing around but never really lining up. Not worth the paddle. Sunday the 6th sees some crazy long-period energy (20 seconds!) from the SSW, pumping 2901, but with 19-22 mph cross-winds it's just a bumpy mess. You'll be watching from the beach.
Now, Monday the 7th... That's our next genuine standout. Monday morning looks absolutely beautiful. Glassy again, winds from the east at a mere 3 mph, and a clean 7ft SSW groundswell with a 14 second period. Wave energy is strong at 2574. This is excellent surf for those who know what they're doing – the long period will hold up well on these reefs and points, giving you some real push and shape. The afternoon stays clean enough with a light cross-shore, but the morning is the clear winner here.
The next few days into the second week taper off in size and quality as winds swing onshore or stay messy. Tuesday the 8th has some small, clean-looking waves but they're weak. Wednesday and Thursday drop right off.
We hit another interesting pocket around Monday September 14th. The morning offers a clean 7ft SSW swell at 13 seconds, but it's got a moderate cross-shore. It's marginal but rideable for the keen.
But the real long-range promise lands on the morning of Wednesday, September 16th. It's glassy again, winds are a light 3 mph from the SE, with a solid 7ft SW groundswell at 14 seconds. The energy is strong at 1557. This looks excellent for experienced surfers again. It's far out, so don't book your flights yet, but the signs are strong.
Finally, Friday morning, September 18th is a monster. A colossal 18ft SW swell with a 16 second period hits, and the energy is an insane 29923. But here's the thing – the wind is a 25 mph cross-shore. For paddle surfing, that's too big and too windy at Robberg. But if you're into foil or kite surfing, that set-up looks far more interesting than anything on a surfboard.
So, to boil it down: Thursday the 3rd and Monday the 7th mornings are your absolute best bets for clean, powerful surf in the first week. The 16th and the 18th are the long-range potentials, but the 18th is for the kite crew only. Keep your eyes on the forecast, because things can change.
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.
