The Lowdown

Right, let’s have a look at what’s coming up for Robberg. This is a beach and reef setup, exposed to the swell, and it’s inconsistent, so we’ve got to pick our moments.

We’re looking at a bit of a slow start, but there’s some real promise later on. The water’s sitting at 60°F which is a bit colder than normal for this time of year.

First up, Wednesday the 26th is a write-off, really. We’ve got a 8ft SSW swell with a 16-second period (that’s groundswell, meaning long lines and longer waits between sets), but a strong cross-shore wind is messing it all up. The wave energy is very strong (3862), but you’re fighting a lumpy cross-chop.

Thursday the 27th morning is still messy with a 7ft swell and cross-shore wind, though the energy is still solid (1664). The standout comes on Thursday afternoon: the swell drops to 5ft from the S with a 12-second period and a light cross-offshore breeze. The groomed, clean conditions (1362 energy) will make for excellent surf for the experienced crew.

Friday the 28th sees the swell easing further to 5ft and 4ft from the S, with onshore winds and light breeze. Not the best, just marginal.

Saturday the 29th drops off into small, choppy surf – not worth paddling out.

Sunday the 30th morning is marginal with a short-period 7ft SSW swell and cross-on wind. But hold up – Sunday afternoon is a treat: glassy conditions, a clean 5ft SW swell with a 13-second period (869 energy). That’s the pick of the first week if you can get out.

Monday the 31st is tiny and ordinary.

Tuesday the 1st of September kicks off with a 6ft SW swell and light cross-on, but the afternoon turns nasty with a huge 13ft SW swell and a 14-second period, but hammered by strong cross-onshore winds (10401 energy) – that’s a messy, dangerous beast, only for experts if at all.

Wednesday the 2nd is still big with a 12ft SW groundswell and moderate cross-shore wind (3544 energy). Not pretty.

Thursday the 3rd morning is a so-so 6ft SW swell. But Thursday afternoon is a real gem: an 12ft SE swell with a short 8-second period and a clean offshore wind from the N. Despite the short period, the clean conditions and big size (1472 energy) make it excellent for experienced surfers.

Now, let’s talk about the major standout. Friday the 4th of September: a massive 20ft ESE swell arrives in the morning with a cross-shore wind (9855 energy). The afternoon goes absolutely mental with a 23ft ESE swell and a 12-second period, light offshore breeze – the swell is just too big for this break, even though the conditions are favorable for experts. The energy is overwhelming (15111).

Saturday the 5th of September keeps the big swell going: a 12ft ESE swell with a 13-second period and a cross-offshore breeze, giving clean, exceptional conditions for expert surfers (7926 energy). That’s the real highlight for the second week.

Sunday the 6th eases to a 6ft ESE swell in the morning, then a clean 5ft SSW groundswell with glassy conditions in the afternoon (2097 energy) – a nice end to the weekend.

The rest of the week into the 8th and 9th sees smaller, cleaner swells (4ft and 4ft SW with glassy conditions on the 8th) but they’re less consistent. The 10th is poor again.

So, if you want the absolute best, aim for Thursday afternoon the 27th for the clean 5ft S swell, and then the real monster is Saturday the 5th of September with that 12ft ESE swell and clean winds. Keep an eye on the forecast – it’s a long way out, but it looks promising.

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.
