The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Haardebaaai.
Sunday the 30th is an absolute no-go. Strong onshore wind and ugly, poor surf – leave your board in the car. Monday the 31st is barely better; light cross-onshore wind and just marginal, sketchy conditions.
But Tuesday, September 1st? That’s the one. The morning session is the best we’ve got in this whole 16-day stretch. Swell is a solid 10 ft from the SW with a nice long 13-second period – that’s proper groundswell. The wind is light and cross-offshore, so it’s clean. For a reef break, that long period will really stand it up for the experienced crew. The combined energy is strong at 2679. Water temperature is a touch colder than usual at 59°. Tuesday afternoon has a cross-shore wind and trickier tides, so make it the morning. Crowds are possible, so beat the rush.
Wednesday the 2nd is blown out again. Onshore wind kills it.
Thursday, September 3rd sees a monster 25 ft swell from the SSW, but it’s way too big for this sheltered reef. The energy reading is insane at 14612, but it’s only for experts, and the cross-wind won’t clean it up. Skip it.
From Friday the 4th through to Tuesday the 8th of September, you’re looking at a five-day dead zone. Strong onshore winds, lumpy chop, and tiny, weak surf. The energy drops to almost nothing – 75 or 68. Not worth a look.
There’s a small hope on Thursday, September 10th. The morning has a clean 3 ft swell from the WSW with clean cross-offshore winds. The afternoon swings to a 7 ft swell from the SE, but with a short 6-second period – that’s just windswell with no grunt. Energy is moderate at 639. It’s ‘expect good surf conditions’, but it’s not a highlight.
From Friday the 11th through to Monday the 14th, it’s a mess again. Strong winds, near-gale gusts, and blown-out surf. Monday afternoon turns offshore, but at 25 mph, it’s clean but a nightmare to paddle into.
So, the one and only standout window is Tuesday morning, September 1st. Don’t miss it. The rest is mostly a wait-and-see.
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.
