The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The only spot on the radar for this stretch is Robberg, and it’s a bit of a mixed bag. The forecast is a long one, 16 days, but don’t expect a constant party. We’re looking at some serious wait time at the start, with nothing really worth paddling out for.
We kick off on Sunday, 9th August, but honestly, it’s a write-off. A solid 10ft SW swell is running, but the cross-on wind is just shredding it. The wave energy is powerful (2967), but it’s messy and choppy. That’s a pass from me.
The first real glimmer of hope comes on Wednesday, 12th August. The morning session is the standout of the whole outlook. A clean, long-period groundswell of 3ft from the SSW, with a period of 20 seconds, is pushing in. The wind is light and cross-offshore, making for clean conditions. The combined energy is moderate (1539), but that long period will give you some real shape and easy paddling between sets. This is the one to circle on the calendar for experienced surfers.
Thursday, 13th August, also looks promising. The morning is clean again with a light offshore from the NNE and a 5ft SW swell (16 seconds). The energy is ramping up (3536), and the conditions are excellent. Thursday afternoon and Friday, 14th August, keep the quality going with clean, cross-offshore winds, though the swell drops a bit.
After that, the surf gets a bit ordinary. There’s a small window on Sunday, 16th August, where the afternoon turns glassy with a tiny 4ft E swell, but it’s not going to get the heart racing. The combined energy is weak (392). We then get a couple of days of small, weak waves.
The second week is more of a gamble, with a lot of average to poor conditions. The models are showing some size again, but the winds are questionable. Monday, 24th August, has a decent 7ft SW swell but with a light cross-onshore wind, so it’ll be a bit bumpy. It’s a long-range call, so keep an eye on it, but don’t hold your breath.
For the standout, it’s got to be Wednesday morning, 12th August at Robberg. That’s your best chance for a clean, quality session on a long-period groundswell.
Rusty, signing off.

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.
