The Lowdown
Alright, Rusty here. Let’s talk about what we’ve got coming up at Haardebaai.
First thing you need to know: this spot is a sheltered reef, advanced only, and it needs a good NW offshore to really shine. The water’s sitting at about 60°, which is bang on average for this time of year – nothing weird going on there.
Right now and through the first few days, it’s not exactly firing. The swell is there, around 4ft to 4ft from the SW with a solid 13-14 second period (that’s proper groundswell energy), and the combined energy is moderate, sitting between 494 and 964. But the winds are all over the place. Sunday morning looks like the first real chance with a light cross-off breeze from the NNW cleaning things up, and then Sunday afternoon goes glassy with the WSW wind dropping to zero – that’s the kind of clean you dream about. The waves will be around 4ft and glassy, but the overall quality is still just ‘good’, not a standout.
Monday morning is also glassy with a light SSE breeze, and the swell period bumps up to 14 seconds, with combined energy hitting 964 – the best of this early stretch. But again, the score tells me it’s just okay, not epic. Tuesday afternoon goes glassy again but the swell drops to 4ft. It’s surfable, but ordinary.
Now, hold on. Wednesday the 5th of August – things get serious. The swell jumps to 7ft in the morning, then 10ft by the afternoon, coming from the WSW with a 14-second period. The combined energy rockets up to 1997 and then 3408 – that’s strong energy. But here’s the catch: the wind is howling from the NW at 30 km/h. Morning is cross-off and clean, but afternoon is full offshore. This is big, clean, powerful reef surf. But at 10ft, this is expert territory only. It’s the best on offer so far, but you need to know what you’re doing.
Thursday the 6th of August is the true standout for the whole outlook. Morning session: 13ft of SW swell, 13-second period, combined energy of 5362 – that’s very strong. And the wind? Glassy. NE at 5 km/h. That’s a rare combination. The data says “excellent surf conditions for experienced surfers” and I’m not arguing. This is the one. However, by the afternoon the wind swings onshore from the SE at 20 km/h and it’s blown out. So you’ve got a narrow window: Thursday morning is your absolute best bet.
After that, Friday the 7th sees 10ft but with cross-onshore winds, making it messy. Saturday the 8th is a write-off – near-gale force winds and rain. Sunday the 9th has a massive 21ft S swell, but it’s too big for the break and onshore – that’s more for the kite crew than paddlers.
There’s then a gap from the 10th to the 12th with very little to no surf. The 11th has a tiny 1ft, 20-second period swell – long period but no power.
Things start looking up again on the 15th of August. Saturday morning: 8ft WSW swell, 16-second period, combined energy of 2882, and glassy conditions with a NE breeze at 5 km/h. That’s another excellent window for experienced surfers. Sunday the 16th of August is also good: 10ft SW swell, 15-second period, and offshore winds from the NNW in the morning, then NW in the afternoon. Both sessions are clean and powerful.
So to sum it up: the absolute best is Thursday the 6th of August morning – big, glassy, and powerful. The second best is Saturday the 15th of August morning, also glassy with a long-period groundswell. Sunday the 16th is a solid backup. The rest is either too small, too windy, or too big for the average punter.
Stay safe out there. This reef doesn’t mess around.

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.
