The Lowdown
Alright, let’s get into it. Keurbooms is your spot for the next couple of weeks, and there’s some serious movement in the water. The long-range stuff is still a way off, so keep that in mind, but the shape of this forecast has some real gems hidden in it.
We kick things off with a bit of a flat spell, but don’t get discouraged. There’s a window opening up as we head through the middle of the month. The first real call to get excited about is the Sunday morning, September 13th session. The swell is coming in at a solid 7ft from the SW, with a period of 14 seconds – proper groundswell energy. The wind is dead glassy, which will have it looking like a mirror. This is the standout of the first week, hands down. The water is running really cold at 55°F – that’s 8°F colder than what you’d typically expect for this time of year. You’re gonna need the thickest suit you own, no messing around.
After that, Monday afternoon the 14th also looks tasty. It’s a bit smaller at 7ft with a cross-off wind to keep things clean. Different swell direction though, out of the ESE at 10 seconds, so it might be a bit more lined up than the SW groundswell.
Now, heading into the second week, the forecast gets a bit wild. Wednesday the 16th is looking at a serious pulse of swell – 10ft of SW windswell with 15-second periods in the morning. The wind is favorable, but that size is pushing well past the fun zone for this break. The afternoon cleans up with a 10ft SSW windswell and glassy conditions, but honestly, that’s expert-only territory. It’s too big for most of us. The energy readings are off the charts too, over 4000 on the morning session and strong on the afternoon.
The following week starts to fall back into a more manageable rhythm. Monday the 21st afternoon is another classic: 4ft of SSW groundswell at 15 seconds, with a cross-off breeze. It’ll be clean and lined up. Then Tuesday the 22nd morning is another one where the size jumps back up to 10ft, but this time it’s an ESE windswell, short period stuff at only 7 seconds, and the wind is on it. That’s a combo that will make it a mess, and it’s too big on top of that. A pass.
Overall, there’s plenty to work with over the next 16 days at Keurbooms. The standout windows are the 13th and the 14th, then again on the 21st. Everything else is either smaller, windblown, or just too big to be any fun. The cold water is the story right now, so prepare for that. This is one of those runs where patience pays off – wait for the right window and you’ll be rewarded.

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.
