The Lowdown
Alright folks, Rusty here with a look at what’s coming up for Keurbooms. We’ve got a pretty wild ride over the next couple of weeks, with some proper swell windows and a few days that are flat-out not for messing about. The water is sitting at a cold 57°F at the start, which is a whopping 6°F colder than usual for this time of year – that’s a seriously chilly anomaly, so don’t forget the thick rubber if you’re heading in.
We start off on Saturday the 12th of September with a glass-off. The morning is small, around 3ft from the SW, but that 15-second period and glassy conditions mean there’ll be some tidy little lines. The combined energy is moderate (406), so it’s not packing a punch, but it’s clean and rideable. Saturday afternoon, the swell bumps up to 7ft from the SSW, still glassy, with a huge jump in energy (2168). This is getting solid – intermediate territory, and the sets will be pushing through proper.
Sunday the 13th is where things get heavy. The morning sees a chunky 12ft swell from the ESE, but the wind is a cross-on from the E at 9 mph. With that massive energy reading (3677), this is a beast of a swell, but it’s too big and messy for this break. This is more of a kite-surfing show than a paddle session. Sunday afternoon is worse – same size, stronger onshore wind.
Monday the 14th brings a reset. The morning is clean with a light NW offshore wind and a 8ft ESE swell. This is excellent for experienced surfers – the energy (1551) is strong, and those offshore conditions will groom it nicely. Monday afternoon turns glassy again with a 7ft ESE swell – another cracker for the confident surfer.
Tuesday the 15th is a real treat. Morning and afternoon both serve up glassy conditions, with a 5ft and 4ft swell from the E, periods around 11 seconds. Easy paddling, clean waves, and moderate energy (889 and 825) – this is the pick of the early run for the intermediate crew.
Wednesday the 16th shows us another big jump. The morning has a 10ft SW swell with a 14-second period and glassy wind – energy is through the roof (3785). That’s a lot of water moving around, and it’s expert territory again. Afternoon blows up with a strong S cross-on wind at 16 mph, making it ugly.
After a few poor days, we see a nice little window on Friday the 18th. That afternoon, a 7ft SW swell with a 14-second period and a cross-off wind gives us clean waves for experienced heads. Saturday the 19th is even better – the morning is clean at 8ft, and the afternoon turns glassy with a 7ft SW swell. That afternoon session on the 19th is the standout of the whole forecast: glassy, powerful, long-period groundswell.
The second week settles down a bit. Tuesday the 22nd has a clean cross-off morning with a 6ft E swell. Friday the 25th afternoon is worth a look – clean, 5ft ESE swell. Then on Saturday the 26th afternoon we see another glassy gem: 7ft from the SW. And to close it out, Sunday the 27th morning serves up a 5ft SW swell with a very long 16-second period and clean offshore winds.
There are a few gaps in the second week, a couple of days at a time where the wind starts to mess it up, but the good windows are there if you’re picky.
Stay stoked, and stay warm.

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.
