The Lowdown
Alright, let’s get stuck into this one. We’ve got a bit of a wild ride ahead for Keurbooms over the next couple of weeks. The water’s sitting at 61°F, which is a bit colder than what you’d normally expect this time of year – not crazy, but you’ll want that hood or a good thick suit.
Right out of the gate, Sunday’s a no-go. We’ve got a solid 10ft of swell (SW) with a 13-second period, and while the morning wind is favorable, it’s just too much juice for this break. The energy is cranked up at (2964), but it’s just a washing machine. The afternoon turns into a right mess with a 30 km/h cross-on, so forget it.
Monday isn't much better. The swell drops a touch to 8ft, but the wind is still onshore and lumpy. The afternoon clean-up is ruined by an onshore breeze. We’re not getting anything clean here yet.
Tuesday morning, still too big at 10ft, and it’s cross-on. The afternoon drops to 6ft, but the wind picks up and chops it all out. This early stretch is a write-off.
Then we get a little breather on Wednesday, the 12th. Swell drops right down to 3ft in the morning, but the period is a huge 20 seconds. That long-period energy is just going to close out on this setup. It’s pretty marginal, and the afternoon isn't much better.
Now, here’s where things start to look interesting. Thursday the 13th and Friday the 14th are the first real windows. Swell is around 5ft from the SW with a solid 16-second period, and we’ve got a light cross-offshore wind from the NNE. It’s clean. The water is glassy. This is what you’re waiting for. The energy is still moderate (3289 on Thursday morning), but the conditions are right. This is overhead, powerful, and lining up for the experienced crew. Not for the faint of heart.
Saturday the 15th looks really good too. Swell drops a touch to 4ft, but the period is still 14 seconds. Saturday morning is clean with a cross-off, but it’s Saturday afternoon that's the standout – glassy, only 4ft, light offshore from the south. This is as clean as it gets. This is the one to circle on the calendar for the first week.
Sunday the 16th goes a bit flat, with some weak, short-period E swell. The afternoon is glassy, but there’s just no push. Monday the 17th has a fun-looking pulse in the arvo – 7ft of SW swell at 15 seconds and glassy. That’s got some punch.
Tuesday the 18th and Wednesday the 19th stay in the 6ft to 8ft range, with the arvo’s looking cleaner. The swell is solid, but the winds are a bit more up and down. Thursday the 20th turns into a bit of a mess with onshores.
Now, hold onto your board. The 21st of August is when the ocean just turns on. We’ve got a massive 16ft SW swell hitting with a 11-second period. The energy reading is through the roof at (6450). But listen to me – this is way, way too big for Keurbooms. It’s a no-go for paddle surfing. The wind is light, but with that much water moving, it’s just a foaming, roaring beast. This setup is more interesting for the kite crew than anyone on a paddleboard.
That big pulse eases over the weekend, but it’s still solid – 12ft on Saturday the 22nd, still too big. The clean conditions are there, but the size is just prohibitive.
Finally, we get a bit of relief on Sunday the 23rd. The swell drops to 7-8ft and it’s glassy in the arvo. Finally, some size you can handle. It’s still a heaving, powerful wave, but it's back to being an expert’s wave rather than a survival mission.
And then, just to mess with us, the 24th brings another massive pulse – 10ft plus, with a 16-second period. It’s glassy, but again, just too big.
So, overall, the best of the best is Saturday afternoon the 15th – small, clean, and perfect. The other standout is Thursday morning the 13th – a bit bigger, still clean, and powerful. The rest is either too small, too messy, or just plain too big. Keep your eyes on that forecast, because it’s going to change.

Information about the Keurbooms Surf forecast
The above surf forecast table for Keurbooms provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Keurbooms can be found by selecting the local surf guide option on the grey menu. Our Keurbooms 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 (Keurbooms) 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 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.
Keurbooms is 6 km (4 miles) from the city of Plettenberg Bay. If you plan a holiday in Garden Route, look for hotels and other accommodation in Plettenberg Bay. Plettenberg Bay has rooms for a wide range of budgets as well as car hire and transport links.
