The Lowdown
Alright, Rusty here. Let’s break down what Haardebaai has in store for the next couple of weeks. It’s not an instant classic, but there are a few sessions that’ll get your heart racing.
First off, the water’s sitting at 58°, which is a bit colder than usual for this time of year – about 3° cooler. So, grab the thicker wetsuit.
Haardebaai is a sheltered reef break, consistent but for advanced surfers only. The first few days are a bust. Sunday the 6th is blown out with a fresh cross-onshore wind.
The first real chance is Monday morning, the 7th of September. It’s glassy – dead calm with a light offshore from the NW. The swell is a solid 7ft from the SW, with a long 14-second period. That’s proper groundswell, and the combined energy is strong at 1572. It’ll be clean, but that size and period at a reef means it’s for experienced surfers only. Not the top pick, but a good start.
Things go quiet again until a big pulse hits. Thursday the 10th sees a massive 12ft SW groundswell with a 16-second period and combined energy of 5351. That’s a lot of water moving, but the wind is onshore from the SE at 15 mph, and it stays poor. That one’s a miss.
The next real standout is Monday the 14th of September morning. Clean conditions with a moderate offshore from the NNW at 12 mph. The swell is a modest 4ft from the SW at 12 seconds, with moderate energy (656). It’s clean and manageable – a good one for someone who knows the reef.
But the true highlight? Tuesday the 15th of September morning. This is the one to circle. The swell is pumping at 10ft from the WSW with a 13-second period, and combined energy is 3148 – very strong. The wind is offshore from the NW at 12 mph, and the conditions are clean. This is excellent surf, but only for experienced surfers. That’s a solid 10ft at a reef break, so you need to know what you’re doing. Crowds are sometimes an issue here, so you might have some company.
The good run continues on Saturday the 19th of September. Saturday morning is clean with a light cross-offshore wind, 6ft SW groundswell at 15 seconds, and strong energy (1707). Saturday afternoon gets even better: 7ft from the SW at 15 seconds, combined energy of 2061, and clean conditions. That’s excellent for experienced surfers.
Then Sunday the 20th of September morning delivers another standout. Offshore wind from the NW at 9 mph, 8ft SW groundswell at 13 seconds, and combined energy of 2063. Clean, powerful, and good shape. That’s another one for the advanced crew.
After that, the winds turn onshore again, and we’re back to poor conditions by Monday the 21st. So, the window is from the 14th to the 20th, with Tuesday the 15th and Saturday the 19th being the absolute best on offer. Get on it.
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.
