The Lowdown
Alright, let’s break it down for Robberg. Water temp is 57°F, which is 6°F colder than usual—that’s a sharp chill, so suit up.
The first real highlight lands on Monday, August 17th. Morning brings a clean 8ft SW groundswell, 14-second period, glassy flat calm. This is excellent for experienced surfers, with strong combined energy (2118). Robberg is a beach and reef mix, and with that long-period swell, the reef sections could cough up some real gems. Crowds can show up sometimes, but a Monday morning might keep it quiet.
Tuesday, August 18th morning is another one: 6ft SW swell, 13 seconds, glassy again. Excellent for experienced surfers, energy at 1134.
Thursday, August 20th morning: 8ft SW swell, 12 seconds, glassy, energy 1839. That’s expert-only size, but clean as a whistle.
The second week gets big and rough. Saturday, August 22nd afternoon has a massive 18ft SW swell, 13 seconds, but moderate cross-shore wind at 25 mph. Energy is extreme at 11442—more for kite surfers than paddle surfers. Sunday, August 23rd sees 16ft SSW groundswell, 15 seconds, still cross-onshore.
But we get another clean window: Friday, August 28th morning. Glassy, 7ft SW swell, 14 seconds, energy 2304. Excellent for experienced surfers.
Saturday, August 29th morning is glassy with 6ft SW swell, 13 seconds, energy 1266—very good. Afternoon stays clean with 5ft, 12 seconds, energy 948.
First week has the best quality. Second week is bigger but windier. If you’re not solid on a bigger board, give it a miss.

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.
