The Lowdown
Alright folks, Rusty here. Let’s get into the outlook for Haardebaai – a reef set-up that demands respect. We’ve got a bit of a slow start, but there’s some serious potential waiting for the right crew.
The first real invite comes on Tuesday, August 4th, in the morning. It’s small, around 4 ft from the southwest, but with a glassy sea and clean conditions, it’s your best early bet. The water temp is feeling about average for this time of year, so nothing to shock you. The energy is moderate, with a combined swell energy of 423 – not a lot of punch, but it’s rideable and clean.
Then we hit a rough patch. Wednesday, August 5th, brings a massive jump in swell – 8 ft to 8 ft from the southwest – but it’s hammered by a strong 22 mph offshore wind. That’s raw power, with combined energy readings soaring to 2484 and 2614, but it’s a wild, gnarly beast. Only for the experienced, and even then, it’s marginal. The wind stays onshore and messy through Thursday and Friday, with swell pumping 10 ft to 12 ft and energy climbing to 4555. That’s big, ugly, and blown out. For paddle surfing, it’s a write-off. If you’re into kiting, that kind of clean offshore wind on Wednesday might be your session, but for a surfer? Hard pass.
We get a reprieve on Saturday, August 8th. The swell drops to 8 ft from the southwest, and the wind goes light cross-offshore. It’s clean, but the energy is still hefty at 2376. It’s a step in the right direction, but not the standout.
Sunday the 9th is a write-off again with rain and strong onshore winds, and Monday the 10th is a confusing mess of dropping swell.
Now, here’s the real standout to circle on your calendar. Wednesday, August 12th, in the morning. The forecast is for 5 ft of swell from the southwest, a glassy sea, and a combined energy of 1919. The swell is long-period (19 seconds), which means proper groundswell, smooth lines, and long lulls between sets. On a reef like Haardebaai, that’s a dream setup. The water will be glassy, the shapes will be clean, and it’s not too big for a confident intermediate. This is the one to aim for.
The following days (August 13-15) offer a consistent run of 4 ft to 6 ft swell from the west-southwest, with light offshore morning winds. Solid, clean, fun surf. On Saturday, August 15th, the afternoon goes glassy with 5 ft and clean lines – a very nice second wind.
After a brief blowout on Sunday the 16th, we get another promising window. Monday, August 17th, in the morning brings 8 ft of swell from the west-southwest, a clean offshore breeze, and a combined energy of 1726. That’s a lot of power, but clean. It’s a big day for experts.
And finally, for the long-range crew, Wednesday, August 19th, in the morning is a tentative call. The forecast shows 10 ft of swell from the west-southwest, with a glassy, clean offshore wind. The energy is 2475 – that’s serious. It’s a long way out, so keep your fingers crossed, but if it holds, that’s an epic, heavy day for the experienced crew at Haardebaai.
So, to boil it down: glassy, clean, and small on Tuesday morning. The real standout is the glassy, long-period groundswell on Wednesday, August 12th. If you want a big, clean challenge, watch for August 17th.

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.
