The Lowdown
Alright, Rusty here, let's look at what's on the cards for the Plett area, focused on Robberg.
Right now, there's a bit of a wait. The surf doesn't kick in properly until Friday the 11th, so you've got a few days of nothing much to worry about. The water temp is sitting about average for this time of year, nothing weird going on there.
Friday 11th September morning is where it gets real interesting. Robberg is waking up with a solid 6ft SW groundswell, with a nice long 13-second period – that's proper energy heading into the reef. Combined wave energy is pumping at (1176), so there's plenty of grunt. The wind is glassy, 3 mph from the SSE, meaning the surface is going to be like a mirror. This is top-shelf stuff for experienced surfers; you'll be getting long, clean lines off that SW swell, but at this size and with the swell direction matching the optimum, it's not one for the beginners. The vibe is good, but it does get busy here sometimes.
Friday afternoon the wind swings more cross-shore and the quality drops off, so make the most of that morning.
Saturday 12th morning is smaller at 3ft, but it's a clean and glassy start with a super long 15-second period. A bit inconsistent, but the sets that come through will be wonderfully clean and well-shaped if you're on the right part of the reef.
Monday 14th morning brings another real standout. Robberg gets a 8ft ESE swell with a 10-second period and a clean N offshore wind at 6 mph. The combined energy is strong at (1629). The wind is perfect, and the swell's got some power, meaning clean, hollow-ish waves for the experienced crew. The offshore will hold it up nicely. This is a solid session to pencil in.
Through the middle of the week, we see a lot of onshore and cross-shore winds, keeping things a bit messy. A couple of sessions like Tuesday 15th morning are worth a look with 5ft E swell and a dead calm (0 mph) glass-off – super clean but moderate energy at (879). And Tuesday afternoon cleans up a bit too.
Friday 18th September sees a 7ft SW swell, but the cross-shore wind gets up, making it a bit bumpy. Not a stand-out.
Now, Saturday 19th September looks like the absolute pick of the entire 16-day period. Both the morning and afternoon are magic. Morning shows 6ft SW swell at 14 seconds with glassy 3 mph SSW wind. The afternoon dials it up to a gorgeous 7ft SW swell at 15 seconds, still glassy. Energy is bouncing at (1496) and (2016). This is long-period groundswell hitting the reef perfectly, directly matching the optimum direction, with zero wind. A true classic Robberg day in the making, but it's for the experienced folks at that size.
After that, we get a few days of messy, strong onshore winds, particularly Monday 22nd with 28 mph WSW winds. That's not a paddle session. Then the tail end of the period shows some promise again.
Thursday 24th September morning is a return to form – a 6ft SW groundswell with a 15-second period, and glassy conditions from a SSE air. Clean, powerful, and a great option to finish the run.
Remember, for this area, the really good, clean days are spaced out, so don't sleep on the 11th, the 14th, and definitely don't miss the 19th. You'll be kicking yourself if you do.

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.
