The Lowdown
Alright, Rusty here, let’s break down what’s cooking at Haardebaai for the next couple of weeks.
Kicking off slow, but the first real opportunity comes Sunday afternoon, August 2nd. Water temp is right around 60°, which is dead average for this time of year.
Sunday afternoon, August 2nd: Clean and glassy. A 4ft SW swell, 12-second period, with moderate energy. The wind is glassy from the SW. A sweet, sheltered reef session.
Monday, August 3rd: Morning’s the call. A 4ft WSW swell, longer period at 14 seconds, and strong energy. Glassy conditions. The afternoon turns onshore, so get out early.
Tuesday, August 4th: Both sessions are clean and surfable. 4ft to 4ft SW swell, moderate energy, with cross-off winds. Fun, but not the highlight.
Wednesday, August 5th: Now we’re talking. A 7ft SW groundswell, 16-second period, and a serious jump in energy. Fresh offshore wind from the NNW. This is a big, powerful day for experienced surfers only. The afternoon holds similar size at 8ft.
Thursday, August 6th: The morning is magic for the experienced crew. 10ft of SW swell, 13-second period, and massive energy with glassy conditions. The text says “excellent for experienced surfers.” The afternoon gets onshore.
Friday, August 7th: Another big day. 10ft to 10ft SW swell, with cross-shore in the morning and clean cross-off in the afternoon. The afternoon session is a gem.
Saturday, August 8th: Morning is a clean 8ft groundswell with fresh offshore. The afternoon is a monster at 12ft, with a strong offshore that’s hard to paddle into. Expert territory, maybe even kite-surfing conditions.
Sunday, August 9th through Monday, August 10th: A rough patch. Strong winds, rain, messy onshores. Avoid.
Tuesday, August 11th: THE STANDOUT. The morning is a 16ft SSW groundswell, 14-second period, with an insane energy reading. The wind is glassy from the NNE. This is a rare, exceptional day for experts only. The text calls it “exceptional.” The afternoon is even bigger at 18ft, but likely too big for this break.
Wednesday, August 12th through Sunday, August 16th: The swell drops. The 13th of August (Thursday afternoon) offers a nice 6ft SW swell with gentle offshore. The 16th (Sunday) has clean sessions in the 4ft to 5ft range with offshore wind, perfect for a relaxed paddle.
The Bottom Line: The absolute best is that Tuesday morning, August 11th. It’s a once-in-a-blue-moon session for the experts. Thursday, August 6th morning is another top-tier pick. For most of us, the smaller, clean windows on the 2nd, 3rd, and 16th are the ones to target.

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.
