The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Haardebaai over the next 16 days.
Right off the bat, I’ll level with you – this is a tough outlook. We’ve got a solid stretch of more than a week with almost nothing worth paddling out for. The wind is howling out of the southeast and east-southeast for days, with speeds hitting 28 to 37 mph, which is just gonna trash the surface. The swell is there, but it’s messy and blown out. The first real window of opportunity doesn’t show up until Monday, September 7th.
The water temp is sitting at 59°, which is about 2° cooler than average for this time of year – so, pretty normal for the season, nothing wild.
Now, for the one standout. Monday, September 7th is where it’s at. The morning sees a light westerly-northwesterly offshore breeze at just 6 mph, and the swell is a solid 7 ft out of the southwest with a 14-second period. That’s proper groundswell energy, and the combined energy is a strong 1514 – you’ll feel that push. The afternoon cleans up even more with a gentle breeze, and the swell holds at 6 ft from the southwest. This is the best you’re gonna get all week. The direction is west, which is the optimum for this reef, so it should line up sweet. The conditions are clean, the energy is there, and it’s a good call for advanced surfers only – 7 ft is pushing into expert territory.
Tuesday, September 8th morning is still worth a mention. The wind goes glassy – dead calm from the south-southeast at 3 mph – and the swell drops to a clean 4 ft from the southwest. It’s a smaller, cleaner option, but the energy is moderate (494). It’s a nice change of pace if the Monday was too big.
After that, the wind swings back onshore and the quality tanks again. The next flicker of hope comes Monday, September 14th. The morning has a fresh offshore northwesterly at 22 mph, with a 8 ft southwest swell on a 15-second period. That’s some serious energy (2881), but the forecast says marginal conditions – likely due to tide issues or that strong wind cleaning it up but making it tricky. The afternoon is a bit lighter and cross-offshore, with a 8 ft swell. It’s a “keep an eye on it” situation, but it’s not a lock.
Finally, Wednesday, September 16th morning offers a late-in-the-game treat. Gentle offshore wind from the west-northwest at 9 mph, with a 3 ft south swell at 11 seconds. The energy is moderate (603), and the conditions are clean. It’s a small, tidy session for a sneaky Wednesday morning.
So, the takeaway: the first week is a write-off until September 7th. That Monday is the standout. September 14th has potential for the big-wave crew, but it’s not a sure thing. The long-range stuff on the 16th is a nice little bonus if you’re patient.
Keep your powder dry, and charge that Monday morning.
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.

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.
