The Lowdown
Alright folks, Rusty here. Let’s take a good look at what’s coming up for the local stretch.
The forecast starts with a solid pulse of swell arriving on Friday, July 31st, and the energy hangs around on and off for the next two weeks. There are a few rough patches with strong winds and blown-out conditions, but there are some real gems in there too, especially for the more experienced crew.
Robberg is a beach and reef setup that’s inconsistent, so you need to be patient. The best of the early action kicks off Friday morning, July 31st. Swell is 4ft from the SW with a period of 13 seconds, clean with a cross-offshore breeze. Combined swell energy is pumping at 1107 (moderate-strong). Water temp is 63°, which is normal for this time of year. That morning session is the pick for the first few days.
The weekend gets bigger. Saturday morning, August 1st, sees 10ft from the E with a period of 9 seconds, but the wind is cross, and the wave comment says marginal. The energy is strong at 2199, but it’s not the cleanest. Sunday morning, August 2nd, is glassy with 7ft from the ESE and 8-second period – the energy is moderate at 913, and it feels mellow, but clean. Sunday afternoon though, that’s the standout: 7ft, glassy, ESE swell with a long 13-second period, energy of 1642. That’s a proper groundswell, and it’s going to be clean and lined up. Not for beginners at that size, but for intermediates and up, that’s the session to aim for.
Monday morning, August 3rd, is still glassy with 6ft from the ESE at 11 seconds – excellent, clean surf. Then the wind turns on Tuesday, and things get messy. Wednesday morning, August 5th, is glassy again with 4ft from the SW and a very long 15-second period. Energy is 1273 – not huge, but that long period will wrap in nicely. Good for a point or reef.
The following week sees a massive swell spike. Thursday, August 6th, morning is a write-off – 15ft from the SW with 15 mph cross-onshore winds and heavy rain. That’s kite-surfing territory, not paddle. But the afternoon calms down with 13ft and a light cross wind, so it’s less dangerous. Friday morning, August 7th, is cross-offshore with 10ft from the SW – clean and powerful for experts. Saturday morning, August 8th, is another 10ft SW swell, but cross wind makes it choppy.
The real standout for the entire forecast is Wednesday, August 12th. Morning is glassy, 12ft from the SW with a 15-second period, energy of 4900 – that’s very strong. The afternoon is even better: glassy, 13ft from the SW with 14-second period, energy of 5972. That is exceptional, but experts only. If you’re not comfortable in waves over 8ft, give this one a miss.
The following weekend, Saturday, August 15th afternoon, is glassy again with 10ft from the SW at 15 seconds, energy of 4680. Another excellent session for the experienced crew.
There’s a long gap of poor conditions from the 10th to the 14th, with onshore winds and weak swell, so don’t bother paddling out then. Focus on the 2nd, 3rd, 5th, and the 12th for the best waves.
Expect some company at Robberg, it gets crowded sometimes, so get out early.
Stay safe, pick your sessions, and I’ll see you in the water.
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.
