The Lowdown
G’day, Rusty here. Let’s break down what’s on the cards for Robberg.
We’ve got a slow start. Thursday the 30th of July is a mess, with a 5ft cross-shore wind swell from the SW and a moderate breeze making it ugly. The combined energy is moderate at 1083, but it’s not worth the paddle. Friday morning the 31st looks a little cleaner, with a 4ft SW groundswell (13 seconds) and a light cross-off breeze, but it’s still marginal. Friday afternoon gets messy again with a short period 8ft ESE wind swell, so skip that.
Saturday the 1st of August has some size, 10ft from the East, but it’s a cross-shore wind and a short period of 9 seconds, so it’s choppy and only for experienced surfers. The energy is strong at 2281, but the quality isn’t there.
Now, here’s the good stuff. Sunday morning the 2nd of August is a real standout. Glassy conditions, zero wind, and a clean 6ft ESE swell with a 9-second period. The combined energy is moderate at 1176, but that glassy surface makes it feel like a dream. This is a beach and reef setup at Robberg, and with that offshore wind (N) and calm conditions, it’s going to be clean. The water temp is about average for the time of year at 64°. This is the best on offer in the early part of the run.
Monday the 3rd has a glassy afternoon with a 5ft SW groundswell (14 seconds), but the morning is a cross-on. Not a write-off, but not the top pick.
The following week, things get big. Friday the 7th of August morning is another gold star. Glassy again, 10ft SW groundswell with a 14-second period, and the combined energy is very strong at 3714. This is for experienced surfers—it’s powerful, but clean as a whistle. The following Saturday morning the 8th of August is absolutely insane: 13ft SW groundswell, glassy, and the energy is a massive 5919. That’s expert-only territory, but if you’ve got the skill, it’s a day to remember.
There’s a bit of a gap from Sunday the 9th afternoon through Monday the 10th, with strong onshore winds and lumpy, messy conditions. Don’t bother.
The middle of the second week sees a massive spike on Wednesday the 12th of August afternoon: 15ft SW groundswell, energy of 10999, but with a cross-shore wind. It’s only for the brave. Then Friday the 14th of August morning brings us back to glassy perfection: 13ft SW groundswell, 14-second period, and an energy of 6908. That’s a proper, heavy, clean groundswell for the experts.
Overall, the standout windows are the glassy mornings of Sunday the 2nd, Friday the 7th, and Friday the 14th. The 2nd is the best for intermediates; the 7th and 14th are for the big dogs. Robberg is inconsistent, so these windows are precious. The wind is the key—when it’s glassy, it’s magic.
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.
