The Lowdown
Alright, folks, Rusty here. Let’s get into what the ocean has in store for us over the next couple of weeks. It’s a bit of a mixed bag, so let’s not waste any time.
We kick things off this Saturday morning, the 15th, and honestly, it’s not worth getting too excited. There’s a little bit of southwest swell around 3.9ft, but it’s got a light onshore wind on it and the water is a brisk 55.6°. That’s a solid 7.9° colder than it should be for this time of year – that’s “why is my wetsuit not thick enough” kind of cold. The wave energy is weak at 648, so you’ll be scratching for anything half-decent.
The next couple of days are pretty slow. Sunday the 16th has a touch more push in the morning with 4.9ft, but a cross-shore wind is going to chop it up. The afternoon fades to almost nothing. Monday morning the 17th is when things start to get interesting. We have a proper southwest groundswell at 7.9ft, with a 14-second period, and the wind is completely glassy. The energy jumps to 2108 – that’s a powerful pulse. This one is for the experienced crew, as that size at Keurbooms is not a beginner wave. It’s going to be heavy and hollow.
Tuesday the 18th keeps the ball rolling with another clean 6.6ft morning and glassy conditions (energy 1398). The afternoon backs off a bit, but Wednesday the 19th brings it back with a 8.2ft morning, and then the afternoon is a standout: 7.9ft of swell, 12-second period, and dead calm winds. Energy is at a strong 1681. This is prime time for the big-wave riders.
Thursday the 20th and Friday the 21st stay in that same powerful zone, with waves sitting around 7.5ft to 8.2ft. Thursday afternoon is another excellent one – glassy with 8.2ft and energy at 1958. Friday afternoon also looks super clean, with the wind dying completely and 7.2ft of SW swell. These are solid, powerful waves, folks. Not the day to be towing a foamie.
The weekend rolls around with Saturday the 22nd offering a smaller 6.2ft in the morning, but the afternoon cleans up nicely with a cross-offshore breeze and 5.6ft. Sunday the 23rd is the one to circle on your calendar. The morning session looks absolutely firing: 8.2ft from the SSW, cross-offshore wind, and a huge energy jump to 2315. This is a proper, powerful groundswell. The afternoon gets a little tricky with the wind turning onshore, but that morning window will be one for the memory bank.
Now, Monday the 24th is where we need to have a serious, serious chat. The swell is forecast to be a monstrous 9.8ft from the SSW with a very long 16-second period. The energy reading is off the charts at 4751 – that is a massive amount of water in motion. The wind and tide are favorable, but that wave is simply too big for Keurbooms. It’s going to be a full-on, dangerous washing machine. This is for elite experts only, and even then, you need to know the reef and river mouth intimately. It’s not a day to be a hero.
After that peak, the swell eases but stays fun. Tuesday the 25th is smaller, around 5.6ft to 5.9ft, but the winds are onshore, making it a bit messy. Wednesday the 26th is back on, with a clean cross-offshore breeze and 7.2ft to 7.9ft of long-period SW swell. The energy is still cooking at 2760 and 2972. Another great stretch for those who know what they're doing.
The end of the run, from the 27th to the 30th, has waves in the 4.3ft to 7.2ft range. There are a few clean windows, particularly on the 29th and 30th when the wind goes cross-offshore. The swell direction stays consistently from the southwest, which suits the break well. It’s more of a pick-and-choose situation, but definitely rideable.
The absolute standout of the entire period is the morning of Sunday the 23rd. That’s the perfect alignment: a solid 8.2ft SSW swell, glassy cross-offshore wind, and a massive energy pulse. Second best is the afternoon of Thursday the 20th – also 8.2ft and glassy. Both of these are for the good surfers amongst us. If you’re not confident in solid overhead surf, you need to set your sights on smaller days like Sunday the 22nd afternoon or the 29th, but remember the water is cold, so suit up properly.
As far as the long-range goes, things are looking promising but less certain. That monster pulse on the 24th is a real wild

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.
