The Lowdown
G’day, Rusty here. Let’s talk about your local spot. We’re looking at Haardebaai, and it’s a real mixed bag over the next couple of weeks. The first few days are a total write-off, so don’t even bother paddling out until Thursday the 27th. After that, there’s a decent window, then it turns real cranky again.
Haardebaai is a reef break, and it’s consistent, so it’s got that going for it. But it’s an advanced wave – you need to have your wits about you. The water’s running at about 59°, which is bang on average for this time of year, so nothing weird there.
Right now through Wednesday, it’s a mess. Tuesday the 25th is all onshore junk – 8 ft from the SW with a strong ESE wind blowing straight across it. Forget it. Wednesday isn’t any better: still cross-onshore, messy as hell.
Thursday the 27th is where it finally turns. The morning shows a clean 5 ft SW swell, light offshore wind from the WNW, and a solid 12-second period. The wave energy’s moderate (955), but the glassy wind makes it look real nice. It’s not huge, but it’ll be fun and clean. Afternoon drops off a touch to 4 ft, but it’s still clean.
Friday the 28th is a step down. Swell hangs around 4 ft from the S, but the wind swings cross-on, light. It’s marginal – surfable, but you’ll be working for it. Same deal Saturday morning with a clean but smaller 5 ft WSW swell.
Standout alert: Saturday the 29th afternoon. This is the pick of the first week. We’ve got 7 ft from the WSW, a 14-second period, and a clean offshore wind from the WNW. The combined energy jumps to a strong 3084. This is proper reef-swell territory – long period, groundswell, will line up nicely. That said, 7 ft on a reef is expert territory, no place for beginners. The crowd factor here is “sometimes” busy, so expect a few heads out but nothing nasty.
Sunday the 30th turns bad again – onshore wind, lumpy 8 ft to 8 ft. No good. Monday the 31st is still blown out.
Then we get a late run. Tuesday the 1st of September morning shows 7 ft from the SW with a fresh offshore wind – clean but on the smaller side for this spot. The afternoon though… 10 ft from the SW, 14-second period, offshore wind, and a combined energy of 3908. That’s powerful. It’s only a 3 out of 10 on their scale, but that’s because it’s a beast – experts only. Crowds might be about.
Wednesday the 2nd of September morning is the biggest of the whole run. 13 ft from the SW, 14-second period, fresh offshore wind, and a massive 6021 combined energy. This is not a day for the faint-hearted. The long period makes it a proper groundswell, so it’ll hold up on the reef, but it’s for experienced surfers only. Afternoon drops to a cross-off wind, still 13 ft, but not as clean.
After that, it falls apart. Thursday the 3rd is messy cross-on junk, then Friday the 4th and Saturday the 5th are small and blown out. Sunday the 6th through to the 9th of September is all onshore, small, and poor – a long gap of useless surf.
So, if you’re paddling out, the clear standout is Saturday afternoon the 29th of August – 7 ft SW, offshore wind, clean. And for the brave, Wednesday morning the 2nd of September – 13 ft SW, offshore, just a monster.
Rusty out.

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.
