The Lowdown
Alright, folks, Rusty here. Let’s break down what’s happening at Haardebaai for the next couple of weeks.
It’s a rough start. The first few days have plenty of swell, but the wind is blowing hard onshore, turning the ocean into a mess. You’ll be sitting on the beach for the early part of the week. The first real chance comes on Friday afternoon, August 7th. The wind switches to a light cross-offshore from the WSW, and we’ve got a solid 12ft SW groundswell with a long 15-second period. The combined energy is massive at 5020 (strong to very strong wave energy). This is serious, powerful reef-break stuff for the experienced crew only. Anything over 8ft is expert territory, so keep that in mind.
Saturday morning, August 8th is another gem. The swell drops to a still-chunky 8ft from the SW, but we get true offshore wind from the WNW, light breeze. It’ll be glassy, clean, and the energy is still a heavy 2340. This is a window for the advanced surfer to get some absolute beauties.
After that, it goes ugly again. A strong onshore wind from the SSE blows through Sunday and Monday, wrecking the surf. There’s a long, quiet gap from Sunday the 9th right through until the end of the second week. The swell drops, and the wind stays nasty from the east or southeast, leaving the conditions lumpy and blown out.
Things start looking better around Friday, August 14th. It’s smaller, but we get a clean morning with a gentle offshore from the WNW and a 4ft WSW swell. The energy is modest at 615, but it’s clean and rideable. That pattern holds into the weekend—small, clean, and manageable. Monday morning, the 17th is another good call for a quieter session, with a 4ft WSW swell and a moderate offshore breeze from the NW.
Then, a real wildcard for the long-range. Tuesday, August 18th shows a massive pulse of 12ft SW swell coming back in. The wind is onshore from the SE, but light, so it might just be workable for the experts. The energy is huge at 3038. This one is a fair way out, so it’s promising but not locked in. Worth watching.
The window closes with a few clean, small days—Wednesday the 19th and Thursday the 20th—with offshore winds and tiny 2ft to 5ft waves. Fine for a longboard or a beginner, but nothing to get excited about.
Water temperature is sitting at 60°F with an anomaly of -0.4°F, so it’s about average for the time of year.
Summing it up: the best of the best is Friday afternoon the 7th and Saturday morning the 8th. Those are the sessions for the big kids. The rest is a lot of waiting and a few small, clean windows for a paddle.
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.
