Table - best surf conditions forecast for Robberg over the next 16 days.
Alright, Rusty here again, giving you the lowdown on Robberg for the next 16 days. We're gonna use feet and miles per hour for this one.
It's a slow start, no doubt. The first week is a bit of a mixed bag, but the real heavy stuff is gonna be in the second week. The early days are just a warm-up.
Kicking off on Saturday the 11th of July, Robberg is seeing some lumps, but it's a bit messy. We've got an 8ft SSW swell rollin' in, but that cross-shore wind is choppin' it up. The wave energy is strong (1794), but it's not a pretty picture. It's a no-go for me.
Sunday the 12th and Monday the 13th are still marginal. Swell drops off a bit, and on Monday, it all goes glassy. The morning of Monday the 13th, we get a 5ft ESE swell, but the period is short, only 8 seconds. That's a weak, windswell vibe. The energy is moderate (599). Not worth paddling out for.
The first real standout is Monday the 13th afternoon. The wind goes glassy, and we get a clean 4ft SSW swell with a 10-second period. It's small, but the energy is still moderate (576). It's a nice, clean little session for a log or a funboard.
Tuesday the 14th is glassy again, with a 5ft ESE swell. It's clean, but it's not going to blow your mind.
Now, here's where it gets interesting. You wanna wait for the second week. The 16th of July kicks off a big run of swell, but it's accompanied by a light cross-shore wind. There's a 10ft SW groundswell, with a 14-second period, and the energy is pumping (3361). It's a heavy, powerful wave, but the wind is a bit of a side-shore. For the experienced crew, it's worth a look, but it's not the pick of the week.
The absolute standout is the afternoon of Friday the 17th of July. We get an 12ft SW swell with a 12-second period, and the wind is glassy. The wave energy is massive (3889). This is a bomb for the experts. The conditions are excellent, and the sets will be fat and powerful. This is a day for the big boards and the brave.
The 19th of July, Sunday morning, is another glassy day with a 10ft E swell. The energy is strong (3271). The only issue is that short period (9 seconds) means it might be a bit crumbly, but with glassy conditions, it's still a good session.
The real highlight of the entire forecast is the 22nd of July. Wednesday morning, we've got an 8ft SW groundswell, but the period is a massive 16 seconds. This is a very long period groundswell. The energy is very strong (3561), and the wind is glassy. This is a point break or reef type of swell, so at Robberg, which is a beach and reef setup, it could be a bit straight and walled up. But for the experienced surfer, this is a day of incredible, long, loping lines. The 24th of July, Friday afternoon, is also a monster: a 13ft SW swell with a 15-second period, glassy wind, and the energy is off the charts (7451). Very heavy, expert-only territory.
The water temperature on the 11th of July was 62°F, which is a touch cooler than the long-term average for this time of year. It's about what you'd expect for a South African winter.
Robberg is a beach and reef spot, and it's inconsistent. When it's on, it's on, but it can be a bit fickle. The crowds are "sometimes" an issue, so you might have the place to yourself on a midweek morning.
So, to wrap it up: The first week is a bit of a write-off, but the second week absolutely fires. The best on offer is the Friday the 17th of July afternoon for the glassy, powerful swell, and the Wednesday the 22nd of July morning for the super-long-period groundswell. These are for the experienced crew. For the rest of us, the Monday the 13th of July afternoon is a nice, clean little session.
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.
