The Lowdown
Alright, Rusty here, checkin' in with the local outlook for the Robberg area over the next couple of weeks. Let's get straight into it.
We've got a bit of a slow start, but the good news is there's real, solid groundswell on the horizon. The first few days are all about the build-up, with some size coming through but wind and conditions not quite playin' ball. The real standout windows are gonna be the morning sessions, especially when that wind drops off.
Alright, Friday morning the 14th, we've got some solid 5 ft SW groundswell with a 16-second period. That's a long period, meaning real energy and power, but the wind is a gentle offshore from the N. The water is a nippy 57°, which is 6° colder than normal for this time of year – that's a serious chill, so you'll want a good wetsuit. The combined energy is a powerful 1503 (moderate to strong). This is excellent for experienced surfers only, as it's over 5 ft and that long period makes it punchy. The breaks are a beach and reef setup, so the long period might make it a bit walled at the beach, but the reef could hold it well. Friday arvo, the wind swings to a cross-on from the SW, and the quality drops right off. Not worth it.
Saturday and Sunday the 15th and 16th are a write-off for good surf. The swell drops in size, the wind is messy, and the energy is weak. The Sunday arvo has a tiny 2 ft E windswell with a 7-second period and only 51 energy – dead flat. Don't bother.
Monday morning the 17th is the first real standout. We've got a clean 8 ft SW groundswell, period of 14 seconds, and it's glassy. The combined energy is a beefy 2121 (strong). This is a solid, powerful swell with no wind. It's over 8 ft though, so this is experts-only territory. The crowd factor is rated as "sometimes", so you might have some company, but for a wave this good, it's worth it.
Tuesday the 18th and Wednesday the 19th are a bit of a mixed bag. The swell stays big (6 ft to 8 ft), but the wind is a light cross or cross-on, which messes up the face a bit. It's surfable, but not the clean perfection of Monday.
Thursday morning the 20th is another solid window. The swell drops slightly to a clean 6 ft from the SW, with a 12-second period, but the wind is glassy. The combined energy is 886 (moderate). This is a much more manageable size for a strong intermediate, and the glassy conditions will make it look like a postcard. This is your best bet if you want a powerful session without the huge size of Monday.
The end of the week (Friday 21st) is a bit average with cross-on winds.
Now, get ready for the real monster. Saturday the 22nd and Sunday the 23rd. We're looking at massive swell. The Saturday arvo hits 18 ft from the SW at 15 seconds, with energy readings of 12730 (very strong). The Sunday morning is still a massive 15 ft from the SSW. The wind is manageable, but this is for the absolute elite. This is a proper big-wave event. The forecast scores for these days are high, and the raw power will be unreal. But the wind is cross or cross-on, so it won't be perfectly clean. Still, if you're charging, this is the real deal.
Through the following week, we see a slow drop in size, with 10 ft to 8 ft swell hanging around most days. The wind is a mix of light cross and cross-off, which will keep things clean-ish. The Wednesday morning the 26th, the swell is 10 ft from the SW, but the wind is a clean offshore from the S, with a period of 14 seconds. That's a solid, powerful, clean session for the experts.
The very end of the period (Friday 28th onwards) has the swell dropping and the wind picking up, so the quality fades.
Summary: The two true standouts are Monday morning the 17th for a big, clean, glassy groundswell that experts will love, and Thursday morning the 20th for a still-powerful but more accessible swell with perfect glassy conditions.
Stay safe, read the ocean, and charge it.

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.
