The Lowdown
Alright folks, Rusty here. Let’s check out what’s cooking at Robberg. The first few days are a total dud – messy cross-shore winds and lumpy chop, with the swell all out of sorts. There’s a real dry spell until the middle of next week before anything starts to look promising.
The water is sitting at 61°, which is a bit colder than normal for this time of year, so you’ll want that thick rubber.
The first sign of life is Monday, September 7th. Robberg (beach and reef) gets a 7ft SSW swell with a 14-second period. The energy is solid, with a combined energy reading of 2981. The wind is light and cross-shore, so it’ll be a bit rippled but still surfable. It’s only marginal, though. Conditions stay in that “marginal but surfable” zone through Tuesday and Wednesday, with the swell fading a bit.
The real standout, the one you need to mark on your calendar, is Saturday, September 12th. Saturday afternoon, the wind drops to a light 6 mph cross-shore breeze, and the swell is a pumping 8ft from the SSW with a 16-second period. That’s a long-period groundswell with combined energy over 5000 (5442 to be exact). For a beach and reef setup, that long period will mean powerful, proper lines. This is for experienced surfers only at that size, but it’s the best of the whole window. The morning also looks clean with a cross-offshore breeze, though the swell is a touch smaller.
Then on Sunday the 13th, the swell is still solid at 8ft, but the wind is a moderate 12 mph cross-shore, chopping it up a bit. The energy is still there (3303), but it won’t be as clean as Saturday.
Later in the window, look at Tuesday, September 15th. The afternoon session sees a clean 8ft SSW swell with a 12-second period and light offshore wind. The combined energy is 1706. Conditions are described as excellent for experienced surfers, and the wind is light and clean. That’s a great option.
The very end of the forecast, on Saturday, September 19th, has a morning of glassy conditions. The swell is a smaller 6ft from the SSW, but with zero wind, it’ll be as smooth as glass. The energy is 809, so it’s a fun, mellow day for the intermediate crew.
Stay safe out there, and don’t sleep on that Saturday the 12th.
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.
