The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for Haardebaai.

We’ve got a proper groundswell rolling in to kick things off, but you’ll need to earn your waves. The standout window is from Thursday the 13th through Monday the 17th, with a few other windows of fun surf later on. There’s a big ugly gap from Wednesday the 19th all the way through to Tuesday the 25th, where the wind and conditions just turn to junk, so don’t bother planning around that.

Thursday morning, August 13th is where we start. Haardebaai is pumping for experienced surfers only. It’s a reef break and it’s handling a solid 8 ft swell out of the SW, with a very long 17-second period. That’s proper groundswell, meaning the sets will have some serious energy – we’re talking 3307 for the combined energy. The water’s a bit colder than normal for this time of year at 58°, so grab an extra mm. Wind is a light NNE breeze at 6 mph, cross-off, making for clean surf. This is your best shot for the whole run if you’ve got the skills. The wave quality and consistency are there.

Thursday afternoon holds similar, with 7 ft SW at 16 seconds, still cross-off and clean. Still excellent, still expert territory.

Friday the 14th drops off a bit. Morning sees 6 ft WSW at 15 seconds, with a moderate NNW offshore breeze at 16 mph keeping it clean, but the quality is a step down. It’s still good, but not the standout. Afternoon is similar with 6 ft and 14 seconds.

Saturday the 15th is a write-off. Light cross-onshore wind and questionable conditions. Not worth the paddle.

Sunday the 16th we get a nice comeback. Morning is clean with a moderate NW offshore at 12 mph, 6 ft WSW at 14 seconds. It’s a solid option for a bigger lineup. Afternoon the wind goes cross-off, still clean, with 7 ft at 15 seconds.

Now, Monday the 17th morning is special. Glassy conditions, not a breath of wind, and a crisp 8 ft WSW swell at 13 seconds. The wave energy is strong at 2154. This is the second real standout for experts. The glass makes it perfect. Afternoon gets a bit messy with cross-on wind, so get out early.

Then we hit that ugly stretch. From Tuesday the 18th afternoon through to Tuesday the 25th, the wind is onshore, strong, and messy. Swell stays around but the quality is poor. You get a few clean moments on the 18th morning and on the 25th afternoon, but they’re marginal at best.

Tuesday, August 25th afternoon is the first glimmer of hope after the lull. A moderate WNW offshore at 12 mph and 4 ft SW at 12 seconds, clean, but tiny. Worth a look if you’re desperate.

Thursday, August 27th sees a decent return. Morning has 5 ft WSW at 12 seconds with a moderate NW offshore at 16 mph, clean. Afternoon is 6 ft at 12 seconds with a WNW offshore. Good clean waves, but not the size or energy of the first week. Friday the 28th is a lighter option with fresh offshore wind.

All in all, your two absolute best days for the experienced crew are Thursday the 13th morning and Monday the 17th morning. Everything else is a backup.

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.
