The Lowdown
Alright folks, Rusty here, giving you the lowdown on Haardabaai. This is a reef break that demands patience, and we’ve got a whole lot of waiting to do. For the first ten days or so, it’s just not happening. The wind is blowing a gale from the east and southeast, making everything a choppy, blown-out disaster. Even when there’s a big swell—like a solid 8ft on the 12th—it’s being trashed by a 31 mph cross-on wind. Total write-off.
There’s a small window on Monday morning the 14th with a fresh offshore wind, but the swell is only 4ft and the conditions are “marginal.” Tuesday the 15th sees a bump to 8ft, but the period is a shocking 6 seconds, which is just junk on a reef.
The first real day of peace comes on the morning of Sunday, the 20th. It’s glassy as a mirror, with a light southeasterly breeze, and a clean 4ft SW swell pushing in. It’s small, but it’s your first chance at a proper, clean surf. The energy is low, only 495 (combined energy of all swells directed here), so grab a log and enjoy the quiet.
But the one you’re waiting for—the big one—is the morning of Friday, the 25th. The wind is nearly dead calm from the east, and we’ve got a massive 10ft groundswell from the SSW with a long 16-second period. The energy is a staggering 4858 (combined energy of all swells directed here). This is a serious, expert-only day. It is excellent, but that kind of size and power on a reef is not for the faint of heart.
After that, it mellows out. The 27th brings a clean 5ft SW swell with a 17-second period and a light cross-off breeze, making for a very good, clean session.
So, to wrap it up: the first week and a half is a howling mess. The clear winner is the glassy, giant swell on the 25th for the experts only, and the 20th is your calm, small-wave entry point.
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.
