The Lowdown
Hey, Rusty here. Let’s break it down in feet and Fahrenheit. The next two weeks at Robberg are a rollercoaster of solid SW groundswell and tricky wind. Robberg is an exposed beach and reef that’s inconsistent, so you’ll need to pick your moments. Water temp is about 62°F, right around the average for this time of year.
First up, Monday afternoon, August 3rd. A clean 5ft ESE swell at 11 seconds, light cross-off breeze from the ENE, and the combined energy is 1228. Decent for experienced surfers, but not a standout. Tuesday morning, August 4th, drops to 4ft from the SW with a 12-second period, cross-off from the NNW, and clean.
The real gem is Wednesday afternoon, August 5th. Glassy conditions, a 7ft SW groundswell with a 16-second period—that’s long-period energy, perfect for a reef. Combined energy is 2237. Clean, punchy, and for experienced surfers only. That’s your best early session.
Thursday, August 6th, gets big with 12ft and 10ft SW swell, but cross-wind and chop make it marginal. Friday, August 7th, is similar—big and messy. Saturday, August 8th, saves the week. Both morning and afternoon are glassy, with 8ft and 8ft SW swell at 14 and 13 seconds. Energy is 2360 and 1830. Clean and powerful. A top session.
Sunday, August 9th, gets messy. Monday, August 10th, through Tuesday, August 11th, is a total loss. 45 km/h and 35 km/h SE winds, heavy rain, 16ft to 13ft swell—dangerous and ugly.
After the storm, Wednesday morning, August 12th, fires with an 12ft SE swell, 10-second period, and a clean cross-off from the NW. Energy is 5701. Exceptional for experts. Thursday, August 13th, has a 13ft SE swell, 13-second period, and a gentle cross-shore. Energy is 8004. Big but rideable for the brave.
The second week calms down. Saturday morning, August 15th, has a clean 6ft SW swell with glassy conditions and a 13-second period. Energy is 1027. A nice, mellow session. Tuesday, August 18th, finishes strong with an 12ft SW swell, 13-second period, and a clean cross-off from the ENE. Energy is 3906. A promising long-range option, but keep an eye on it.
Robberg is inconsistent, so be patient. Crowds are possible. It’s a solid spot when it’s on.
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.
