The Lowdown
Alright, mate. Rusty here, and I’ve got the lowdown on the coming swell window at Haardebaai. It's a bit of a mixed bag over the next two weeks, with a proper wait for the goods, but there’s a genuine standout morning if you’re patient.
First things first, the water temp is sitting at a fairly standard 59°F. That's about par for the course – nothing to wet your wetsuit about, just normal for this time of year.
Alright, looking ahead, we've got a bit of a flat spell to get through. The first few days are a write-off. From Wednesday the 2nd through the weekend, it’s a rough scene. Strong, howling onshore winds in the 18 to 40 mph range, mostly from the south and east, will keep the place chopped up. The swell is messy, and while there’s heaps of energy in the water on Wednesday (over 2600 combined energy), the cross-onshore wind just guts it. Don't bother paddling out. Saturday the 5th is particularly nasty with a near gale blowing right across the face.
The wind finally eases and swings around late Sunday the 6th, but the swell is still on the messy side and the wind is on it. Not the one.
Monday, September 7th – That’s your call to arms. Early morning, mate. This is the best we’re going to see. We get a clean 6 ft south-west swell rolling in with a proper 14-second period – that's pure groundswell energy (1201 combined energy, which is strong). The wind swings to a light offshore from the north-northwest at 15 mph, and the break is sheltered from the east, so it’s going to be clean. This is the one to point the car at. Tuesday the 8th has a much smaller 3 ft clean wave if you need a gentle paddle, but Monday is the standout.
After that, the swell drops right off. We go into a long, quiet gap with barely a ripple through the middle of the week. The wind stays messy (on or cross-on) from the east, and the swell barely registers past 2 ft. A few small pulses show up, but the wind is just garbage.
There’s a flicker of hope again on Monday, September 14th and Tuesday, September 15th. We get a clean 5 ft groundswell with moderate offshore winds from the north-west on Monday morning – that’s another clean session, though it won't have the size of the 7th. Tuesday the 15th bumps up to a powerful 7 ft swell with a very long 16-second period and a fresh offshore, but with 2052 combined energy, that’s a serious, heavy wave for experts only. The period is long so it could be a bit straight and racing at the beach, but this reef setup should hold it nicely. It’s a promise, not a lock, being that far out.
So in short, don’t rush out today or this weekend. Monday the 7th is your no-brainer, clean, solid surf. The later window around the 14th and 15th looks promising but is less certain – keep an eye on it. It’s not a total bust, just a waiting game.
Stay wet,
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.
