The Lowdown
Alright, let me tell you how it’s looking for your local stretch.
Right now, we’ve got a bit of a slow start. The first few days are a washout—strong onshore winds and messy conditions, so don’t even bother paddling out until later in the week.
Things finally turn around on Thursday morning, 27 August. Haardebaai (a sheltered reef setup for advanced surfers) picks up a 5 ft SSW swell with a clean 11-second period and light offshore NW wind at 6 mph. Combined swell energy is moderate at 709, and it’s looking clean. By Thursday afternoon, the swell drops a bit to 4 ft from the south at 12 seconds, cross-off wind, still clean—good for a session if you’re picky.
Friday and Saturday are marginal at best, but Saturday afternoon, 29 August, shows some promise with a 4 ft WSW swell, 14-second period, light cross-off wind, and clean conditions. Combined energy is low at 533, but it’s surfable if you’re keen for a mellow one.
Now, here’s where it gets interesting. Tuesday, 1 September, the swell kicks up to 8 ft SW with a 14-second period, cross-off wind at 16 mph, and combined energy at a strong 2534. This is solid, but the conditions are described as marginal, so maybe not perfect. By Wednesday, 2 September, we’ve got the standout of the whole outlook. Haardebaai gets an 12 ft SW swell at 13 seconds, light offshore NW wind at 6 mph, and combined energy at a very strong 3958. Conditions are excellent for experienced surfers. This is the one to point your board at. Water temp is around 59°, which is about normal for this time of year.
After that, it falls apart again. Thursday and Friday bring strong cross-shore winds and lumpy, messy conditions with big swell—not good for paddling, more like kite-surfing weather. The following week drops off to small, weak, and onshore slop. There’s a small blip on Tuesday, 8 September, with a 5 ft S groundswell at 16 seconds and offshore NW wind, but combined energy is moderate and the surf is ordinary at best. Not worth getting excited about.
So your best bet: Thursday morning, 27 August for a clean, smaller session, and Wednesday, 2 September for the real power.

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.
