The Lowdown
Alright folks, Rusty here. Let’s have a look at the next stretch of days for Robberg. It’s a bit of a mixed bag ahead, so let’s break it down.
We start off with a bit of a quiet patch. Thursday the 27th has some chest to head high swell, around 7ft, but it’s coming from the SSW with a light cross breeze, so it’s going to be a bit lumpy and not really worth fighting for. The water is sitting at 60° which is a bit colder than normal for this time of year, so you’ll want the thick rubber. The energy is solid though, at 1666, so there’s some push in the water, but the quality just isn't there. Friday the 28th cleans up nicely in the afternoon with a glassy surface and 4ft of S swell. It’s small but tidy, a proper longboard or funboard wave, but nothing that’s going to light the world on fire. Saturday the 29th is a write-off with light winds and weak energy, dropping to 321-421, so we’ll be staring at a flat-ish, bumpy ocean.
Sunday the 30th brings the swell back up, over 7ft, but the cross-onshore breeze and chop makes it pretty messy. We’re looking at a lot of moving water but zero shape. Monday the 31st is more of the same, junky cross-on conditions with around 6ft of SW swell. Nothing worth getting excited about.
Now, let's talk about the real standout. Tuesday the 1st of September. The morning is still messy, but the afternoon is where it's at. The wind swings to a light WNW cross-off, which cleans it right up. You've got a solid 8ft of SW swell with a 12-second period, and the energy jumps to 1766. This is the first time in the outlook that conditions align. The wave quality is excellent for experienced surfers. This is the day to get on it before the ocean goes off its head.
And then, hold on to your board. Wednesday the 2nd of September is the one to circle on the calendar. It’s a monster. Overnight the swell just jacks up. Wednesday morning is looking at a massive 15ft of SW groundswell with a 15-second period, and the energy reading blows the doors off, coming in at a huge 9117. The wind is glassy, pure glass. This is a big, serious, expert-only day. This is not a day for the faint-hearted or anyone without a solid quiver. It’s the standout of the entire forecast, pure and simple. The afternoon stays big at 13ft but picks up a light cross-onshore, so the morning window is the one. This is the day you’ll be telling stories about.
After that big day, the ocean takes a turn for the worse. Thursday the 3rd and Friday the 4th of September are blown out. Strong onshore winds from the SSE, hitting 25 mph at times, with huge, lumpy, and unruly surf. The energy is still high, but the conditions are just terrible. Honestly, on Friday, with that 13ft of ESE swell and a fresh cross-onshore wind, this setup looks way more interesting for someone on a kite than for a paddle surfer. You’d just be getting thrashed.
The weekend washes out a bit. Saturday and Sunday the 5th and 6th of September are still big, with 12ft to 16ft of ESE swell, but the cross-shore winds keep things bumpy and hard to read. There’s serious water moving around, but it's messy. A far cry from Wednesday’s perfection.
We get a little respite from the huge stuff on Monday the 7th, but the wind picks up in the afternoon, so it's not great. Tuesday the 8th is a nice little surprise, though. The afternoon is clean again, with a light cross-offshore wind bringing in 6ft of ESE swell. It won't be big, but it should be fun and contestable, a proper rebound session.
The last few days of the window, from the 9th through the 11th, tail off. The swell fades, dropping to under 3ft, and the winds get fluky. The energy is low, and it doesn't look like the ocean has much interest in cooperating. We might see a little bump on the 11th with 6ft of SSW swell, but it's onshore, so it's not looking worthwhile.
So, to sum it up: the first few days are about waiting. The clear standouts are the afternoon of the 1st for a clean, solid session, and then Wednesday the 2nd is the big one, an absolute bomb for experts only. After that, it’s a battle with the wind for a few days, before a smaller, cleaner window on the 8th. Choose your moments, and be ready for that big Wednesday.
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.
