The Lowdown
Alright folks, Rusty here. Let’s have a look at what Haardebaai has in store for us over the next couple of weeks.
It’s a bit of a frustrating outlook, to be honest. The first few days have some serious size but the conditions are a mixed bag, and after that, we hit a long, flat, blown-out spell that’s pretty tough to watch. Haardebaai is a sheltered reef break that needs a good NW offshore wind to really shine, and that alignment just doesn’t line up often enough in this forecast.
The real standout is the window from Tuesday morning, September 1st, through Tuesday afternoon. Monday the 31st of August is a write-off—cross-shore wind, a bit of chop, and marginal energy (1532 combined energy) on that 7ft SW swell. Not worth it.
But then, Tuesday the 1st of September? That’s the one. Early morning brings a clean 10ft SW groundswell (13 seconds) paired with a light NW offshore breeze. That’s a proper session for experienced surfers—the reef will be handling that size with power, and the water is a bit colder than normal at 59°. The combined energy is pumping at 2917, and it just gets better into the afternoon when the swell pushes 12ft (3890 combined energy) with a WNW cross-offshore wind. Clean faces, big, long-period lines. That afternoon is the pick of the whole forecast.
Wednesday the 2nd of September is onshore junk with a solid 10ft swell—don’t bother.
Then from Thursday the 3rd onward, it falls apart. We’re looking at strong onshore winds, near gale force at times, dropping swell down to under 3ft for days. There’s a long gap of poor to flat conditions from Thursday the 3rd right through to around Tuesday the 8th of September. The combined energy drops into the hundreds or lower—weak, messy, and not worth paddling out.
We get a little tease on Wednesday the 9th of September with tiny 2ft glassy waves, but that’s barely surfable. Then another window of poor, onshore junk from the 10th through to the 13th of September.
There’s a flicker of hope on Sunday the 13th of September afternoon—glassy conditions on a 4ft SW swell—but the energy is low (319), and it’s not exactly going to light your world on fire.
The last chance is around Monday the 14th and Tuesday the 15th of September, with a moderate offshore wind and a 5ft SW groundswell. The energy picks up to around 877-907, but the forecast only gives it a marginal or low rating. It might be worth a look if you’re desperate, but it’s not the standout.
So, bottom line: If you’ve got a solid skill set and can make it out on Tuesday the 1st of September, that afternoon is your golden window. The rest of the 16-day run is either blown out or flat. That’s the reality for this stretch.
Rusty.

Information about the Haardebaai Surf forecast
The above surf forecast table for Haardebaai provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Haardebaai can be found by selecting the local surf guide option on the grey menu. Our Haardebaai 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 (Haardebaai) 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 Haardebaai 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.
