The Lowdown
Alright folks, Rusty here. We’ve got a tricky 16-day window ahead for Haardebaai, and I’ll be straight with you – it’s a long wait for anything decent, but there is a glimmer of hope at the end.
The whole period starts off with a lot of wind and messy conditions. The first real recommendation isn’t until nearly the second week, with a whole lot of onshore slop in between. The water here is sitting at about 57°F, which is a good three and a half degrees colder than usual – that’s a notable chill, so a thick wetsuit is a must if you’re suiting up at that break.
So, the best bet on offer? Honestly, it’s the morning of Saturday, September 19th. That’s the standout. We’ve got a clean 2ft of SW groundswell (12 seconds) with a slight cross-offshore breeze. The wave energy is moderate (850), and it’s going to be a clean, lined-up wave at this sheltered reef. The only catch is, this spot does get surfed, and with conditions this clean on a Saturday, you can expect crowds to be likely. Still, it’s your best chance at a proper session.
Leading up to that, there’s a few marginal moments. Monday afternoon the 14th brings a short-period NW windswell at 6ft with a fresh offshore wind – it’ll be clean, but the period is only 6 seconds, so it’s going to be a bit of a bumpy, weak ride.
Tuesday the 15th has a very long period (18-21 seconds) SW groundswell. The size is manageable (4ft-6ft), and the wind is strong offshore, making for clean faces. But the period is so long that these waves are going to be very hard to paddle into at a reef, and the energy is actually high (up to 3233), so it’s a powerful but tricky one. Maybe one for the experts who can manage the extra-strong offshore wind and the slow sets.
After that, it gets messy again until that Saturday the 19th. There’s a distant chance on Tuesday the 22nd with a 7ft SW swell and offshore wind, but the quality is still considered marginal.
To be honest, this is a bleak run for a while. The onshore winds just won’t let up. If you’re not keen on waiting until the 19th, you might be better off checking if conditions are better elsewhere. The setup with all this onshore wind and solid swell does look more interesting for kite surfing than paddle surfing for most of the fortnight.
Things fall away again after the 19th with more onshore wind and bigger, stormy swell. It’s a long dry spell, but that one Saturday morning is the real target. Keep your fingers crossed the forecast holds.
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.
