The Lowdown
Alright, hear me out, Rusty here. We’ve got a solid run of surf coming down the line at Robberg. It’s a beach and reef set-up that’s exposed to the swell, and it’s inconsistent, so don’t expect it to be firing all the time – but when it does, it’s on.
The water is sitting at 62°F, which is about normal for this time of year, nothing out of the ordinary.
We kick off on Tuesday, 4th of August. It’s a slow start with a 4ft SW swell at 11 seconds, but the wind is glassy and the sky is clear. The combined energy is moderate (745), and it’s one of the few windows where the conditions line up right for a decent paddle. The following days, Wednesday and Thursday, see a jump in size. We’ve got a 7ft SW swell on Wednesday afternoon with a 16-second period, but the wind is a touch onshore, making it messy. Thursday morning hits 12ft from the SW at 13 seconds, but that cross-shore wind keeps it from being perfect. The combined energy is strong (4254). This is getting big – over 8ft, so it’s for experienced surfers only.
The first real standout comes Friday morning, 7th of August. The swell is 8ft from the SW, period 13 seconds, and the wind is glassy. The energy is strong (2279), and the wave comment says it’s excellent for experienced surfers. That’s the one to circle. Saturday, 8th of August, is similar – glassy wind, 8ft SW swell, and a solid 14-second period. The energy is 2675. It’s another beauty.
Sunday, 9th of August, the wind rips in at 19 mph from the west, and the swell hits 13ft. That’s a beast, but with that cross-chop, it’s a battle. The energy is massive (5355), but it’s more of a challenge than a pleasure. The following days, Monday and Tuesday, are blown out with onshore winds and lumpy conditions. The swell drops to 5ft by Tuesday morning, 11th of August, with a clean cross-offshore wind, but it’s a short period S swell at 9 seconds. The energy is moderate (803). It’s rideable, but not the best.
We get a bit of a lull mid-week, with Wednesday morning, 12th of August, offering an 8ft E swell but the wind is cross-off, making it clean. The energy is strong (2761). Thursday, 13th of August, is mixed with a 5ft SW swell at 16 seconds, but it’s a cross-shore breeze. The energy is 2366. It’s average.
The second standout is on Friday, 14th of August. The swell is 5ft from the SW at 14 seconds, and the wind is glassy. The energy is moderate (1125), and it’s excellent for experienced surfers. That’s a clean, solid session. Saturday, 15th of August, is smaller with a 4ft SW swell, glassy wind, but the energy is low (484) – a good board for a longboard, maybe.
The run ends on Sunday, 16th of August, with a very weak 2ft E swell and energy at just 92. That’s a flat spell. Then we head into the next week. Monday, 17th of August, shows an 8ft SW swell with a cross-shore wind, but it’s not the best. Then Tuesday, 18th of August, is the real long-range promise: a 10ft SW swell at 14 seconds, glassy wind, and energy at 3728. The wave comment says it’s excellent for experienced surfers. That’s one to watch, but it’s a week away, so keep an eye on the forecast.
The biggest entry is Wednesday, 19th of August, with a 13ft SW swell at 14 seconds, heavy energy (7042), and a moderate onshore wind in the morning, but the afternoon goes glassy with a 13ft swell and 14-second period. The wave comment calls it exceptional for expert surfers. That’s the big one if you’re a charger.
Overall, the best bets are Friday morning, 7th of August, and Friday, 14th of August. For the long-range, keep an eye on the 18th and 19th of August. The spot is inconsistent, so when it’s good, it’s good – but you’ll be sharing the water, as crowds are sometimes an issue.

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.
