The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for Keurbooms. It’s been a rough start—honestly, the first week is a write-off for us. The swell is there, but the wind is just shithouse, with strong onshore and cross-onshore winds tearing up the surface. We’ve got a long gap with no real surf to get excited about from Friday the 4th right through to the end of the first week. The water’s sitting at 60°F, which is a bit colder than we’d expect for this time of year, so you’ll want a decent steamer.
Alright, let’s get into it. The first real glimmer of hope comes on Monday the 7th of September. The wind swings light, almost glassy, and we’ve got a solid 7ft SSW groundswell at 14 seconds. The combined energy is a strong 3232, but the waves are going to be a bit tricky. It’s a long period groundswell, so it won’t be a crumbly beach break—it’ll be lining up with some push, and the offshore wind early might keep it clean. It’s not a standout, but it’s the first time we can paddle out without getting smashed sideways.
Now, the real standout is building through the middle of the week. Mark your calendar for Thursday the 10th of September. The morning is a bit messy with a cross-onshore breeze, but the afternoon? Glassy. Dead flat water. We’ve got a 8ft SW groundswell at 14 seconds, with a combined energy of 2172. This is proper groundswell power, and with glassy conditions, it’s going to be clean, lined-up waves. The direction is from the SW, which is bang on the optimum for Keurbooms. This is the best window of the whole forecast. It’s a bit chunky for beginners—over 5ft—but for intermediate and above, it’s a dream. It’s a fairly consistent spot, but crowds are possible, so get in early.
The good run continues into Friday the 11th of September. Again, glassy conditions with a 7ft to 7ft SW swell at 13 seconds. The combined energy is 1704, and the wind is off the water all day. The waves will be clean, with that long period giving you plenty of time between sets. This is a solid second day of quality.
We hit a hiccup on Saturday the 12th—the wind turns on again, and it’s all chop. But then, Sunday the 13th brings a clean cross-off wind, and a 7ft SW swell at 13 seconds. The energy is 2858, and the wind is coming from the west, which is offshore for this break. The sets will be a bit more powerful, but it’s clean.
The absolute biggest, most powerful swell of the forecast shows up on Thursday the 17th of September. We’re looking at a 10ft SW groundswell with a 13-second period, and the combined energy is a massive 4839. The wind is cross-off and light. Here’s the truth: this is too big for most of us. Over 8ft, it’s expert territory only. The waves will be thumping and the rip will be strong. Good luck if you’ve got the skills, but for the average surfer, it’s a day to watch from the beach. The same goes for Friday the 18th and Saturday the 19th—the swell is 10ft to 13ft, and it’s just too much for the break.
So, to wrap it up: the best of the entire 16-day window is the glassy, clean, 8ft to 7ft SW groundswell on the 10th and 11th of September. That’s your window. The 17th is for experts only. Everything else is a battle with the wind or just too big. Stay keen, and watch the forecasts—they can always change.
Stay wet,
Rusty

Information about the Keurbooms Surf forecast

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 Keurbooms 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.
