The Lowdown
Alright, let me break down what’s happening at Robberg in feet and knots.
The start of this run is flat-out poor. Wednesday the 12th is all cross-shore wind and lumpy crap – don’t even bother.
Thursday the 13th afternoon starts to come good. Swell hits 6 feet from the SW, with a light cross-offshore N breeze at 9 knots. That’ll scrub the bumps. The energy is strong (3058). This is groundswell with a 17-second period, so long lines and plenty of power. It’s one for the better surfers, though – tide and positioning will matter.
Friday the 14th is the gem. Morning brings an offshore N wind at 9 knots and a 5-foot SW swell – clean, rippable. But the afternoon is pure glass: NW wind at 3 knots, almost nothing, with a 5-foot SW groundswell. The period is 15 seconds, so long, smooth sets. Water temp is 62°F – a bit chilly for the season, so a thick suit is wise. That afternoon window is your best bet of the entire run.
Saturday the 15th is a dud – onshore and cross-shore winds ruin it.
Sunday the 16th: tiny and messy.
Monday the 17th brings size back – 6 to 6 feet from the SW – but the cross-onshore wind chops it up.
Tuesday the 18th and Wednesday the 19th stay marginal. Wednesday afternoon sees a big 8-foot SW swell but with an onshore S breeze – that’s big, messy, and only for experts.
Thursday the 20th through Friday the 21st are blown out by strong cross-shore winds. Not worth it.
Now for Saturday the 22nd morning: glassy – S wind at 3 knots, dead flat water, and a solid 7-foot SSW swell with a 13-second period. Power is high at 1601. This is a proper wave, but it’s big, so experienced crew only. Crowds are possible on a day like that.
Sunday the 23rd holds size at 7 to 8 feet from the SW, but the cross-shore E wind puts a ruffle on it.
From the 24th on, the swell tails off to 4 to 5 feet, with mostly light cross-shore winds. Thursday the 27th afternoon goes glassy again – 5 feet SW, no wind – a nice small-wave finisher.
Your two golden windows: Friday afternoon the 14th – glassy and clean. And Saturday morning the 22nd – glassy, big, and powerful. Everything else is a scratch.

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.
