Alright, let's break this down in feet and miles per hour.
We start Monday the 7th with a solid 7ft SSW swell, but it's cross-shore so it's a little bumpy. A lot of energy moving through though (2978). The real gem is Tuesday morning, the 8th of September. The swell drops to a clean 5ft from the east, with a short period of 9 seconds, but the wind is glassy – dead flat. That's a mirror finish. That's your best bet for a fun, clean one.
Then we hit a flat spell. Wednesday the 9th is nearly nothing, with a weak 2ft swell. Energy drops right off (436). The wind is light, but there's just no wave.
Things pick up again Thursday the 10th. A 4ft SSW groundswell with a real long 17-second period, pushing energy to 1440. It's a bit onshore, but those long lines will have nice shape. The standout for this week is definitely Friday morning, the 11th. We've got a 7ft SW groundswell (1777) with a 14-second period, and the wind is dead calm – glassy. That's excellent for the experienced crew.
The weekend gets messy. Saturday the 12th has a cross-shore wind hitting 15 mph, making it choppy on the 5ft swell. Sunday the 13th is similar, more energy but still cross-shore. The following Monday afternoon, the 14th, is another glassy moment with a 4ft SW groundswell – clean and tidy, but small.
The second week gets rowdy. The 15th and 16th see some bigger, lumpy swells in the 8ft to 8ft range, but winds are strong and cross-shore, creating a lumpy mess.
Now for the big one. Friday the 18th of September. This is a beast. The morning has a 13ft ESE groundswell (3533) with offshore winds from the north – clean. That's big, experts only. The afternoon is even bigger – a 16ft ESE swell (5096) with glassy conditions. This is exceptional, but you need to be a pro. The period is 10 seconds, so it's a bit peaky, but the power is insane. This is the big standout, but it's a long way off, so keep an eye on the forecasts. Saturday the 19th is still huge, 12ft to 13ft, but the wind turns onshore, so it'll be a washing machine.
The end of the outlook, around the 20th and 21st, settles back to a more manageable 6ft to 5ft, but the wind is onshore again, so it's a bumpy finish.
For the consistent surfer, Tuesday the 8th and Friday the 11th are your clean, solid days. If you've got the nerve, keep an eye on that Friday the 18th potential.

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.
