The Lowdown

Alright, Rusty here. Let's talk about what's cooking for Robberg over the next couple of weeks.

Alright, Robberg is a beach and reef setup, exposed to the swell, but this spot is inconsistent, so it can be a bit of a tease. The water temp is sitting at 59°F, which is 5°F colder than normal for this time of year – that's a significant chill, so you'll want a thick wetsuit if you're paddling out.

The next couple of weeks are a bit of a mixed bag. We've got a lot of marginal conditions to wade through, but there are a couple of windows that look promising. The first half of the period is a bit of a write-off with poor quality, but we start to see some better potential around the 22nd.

Let's break it down. Sunday the 13th through the 22nd is mostly a story of onshore or cross-shore winds and only moderate wave energy, with the combined energy in the 1000s (2904, 3195). The swell directions are a bit confused, bouncing from ESE to SW, which isn't ideal for this break that likes it from the SE. The waves are there, but the quality just isn't.

The first real standout comes on the morning of Tuesday the 22nd of September. We've got a 7ft SW swell with a very long 17-second period. The combined energy is strong at 3574. The wind is a moderate cross-shore from the E at 12 mph, which will add a bit of chop but it's workable. This is a solid groundswell, and that long period will wrap nicely around the reefs. The size is pushing into the intermediate zone, so it's not for beginners, but if you've got some experience, this could be your session.

Now, looking further out, the morning of Friday the 25th of September is a real gem. The wind is forecast to be glassy – a dead calm, slight air from the SE at only 3 mph. The swell is a clean 6ft from the SW with an 11-second period, giving us a combined energy of 730. The conditions are expected to be very good. This is a prime window for clean, fun waves.

Then we've got a big one on the horizon. On Monday the 28th of September, the morning looks excellent for experienced surfers. We're looking at a 13ft SW swell with a short 9-second period, combined energy of 2151. The wind is glassy – calm from the SW at 0 mph. This is a big, powerful swell. The 13ft is definitely expert territory. That afternoon the swell holds at 13ft with a 12-second period and a cross-shore wind, still with strong energy at 4314, but that morning glass is the window to be in the water. This is the standout of the whole forecast.

So, to sum it up, the first week and a half is a lot of "meh", but the morning of the 22nd offers a good, long-period groundswell, the morning of the 25th is a glassy clean-up day, and the morning of the 28th is the big swell prize for the experts. Keep an eye on that last one.

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.
