The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s comin’ down the line for Robberg. It’s a beach and reef set-up, exposed to the swell, and it’s inconsistent, so we gotta be patient. The whole window is a bit of a mixed bag, but there are a couple of sessions that’ll make it worth paddling out.
The first week is a bit of a grind. We’ve got some solid size rollin’ in, but the wind is a real pain. The combined swell energy is strong to very strong (3611), but that east wind at 16 mph on Sunday the 6th is just gonna mess it up. The swell is 7 ft from the SSW with a very long period of 20 seconds, which is proper groundswell, but it’s not clean. That kind of period can make a beach break like this section a bit too straight, but at a reef setup it can be magic. Monday morning the 7th is a little better with a lighter breeze and a 7 ft SSW swell, but the cross-shore wind still has a bit of a ruffle on it.
The real standout is the week after. Saturday the 12th is the one. The morning is glassy, a dream, with a 5 ft SSW swell at 14 seconds (combined energy 2285). The water temp is about average for this time of year. That’s a clean, fun size. But the afternoon is the absolute winner. The wind drops to zero, totally glassy, and the swell bumps up to 7 ft from the SSW with a 16-second period (combined energy 3543). That’s a proper session. It’s a bit solid for beginners at over 5 ft, but for the experienced crew, it’s gonna be firing. Sunday the 13th is a step down with wind on it again, but then Monday the 14th morning glass again with a 6 ft SSW swell.
Then, hold onto your board, Tuesday the 15th morning is glassy again with a 10 ft SW swell (combined energy 2592). That’s expert territory, over 8 ft, and it’s a long period groundswell, so it’ll be powerful. Perfect for the reef sections. The next weekend, Friday the 18th morning, catches another glassy window with an 8 ft SSW swell (combined energy 1975). That’s another solid one. After that, the swell starts to fade and the wind picks up, so the last few days are small and clean or just blown out.
To sum it up: the best bets are the glassy mornings on the 12th, 14th, 15th, and 18th of September. The combined energy is pumping in the moderate to strong range. The biggest standout is the glassy Saturday afternoon on the 12th with that 7 ft SSW groundswell. It’s a long-range call, but it’s looking promising. The inconsistent nature of the break means you gotta be ready when it lines up.
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.
