The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe at Keurbooms. The forecast window kicks off with a fair bit of size and energy, but the wind is going to be the main character for the first few days, making things a bit lumpy and uninviting. We’ve got a solid run of swell on the way, though, and if you can time the glass-off windows, there are some absolute gems.
Right off the bat, Tuesday the 11th is a write-off. We’re looking at a solid 6.9 ft SSW swell with a short, wind-affected period, and a nasty 20 km/h cross-on easterly wind is going to chop it all to pieces. The water temp is sitting at 61.3°, which is a bit colder than normal for this time of year. The combined wave energy is strong (2077), but it's useless with that wind. By the afternoon, the wind picks up to 25 km/h and it's a total mess.
Wednesday the 12th cleans up slightly, but it’s still not on. The morning has a smaller 3.6 ft SSW swell but with a very long 20-second period. That kind of period can make the waves break a bit straight here, plus the cross-on wind (15 km/h) keeps it choppy. The afternoon sees the swell jump to 4.6 ft but the wind goes back to 25 km/h cross-on. Best to sit this one out.
Thursday the 13th is where we start to get a little hope. The morning has a 3.9 ft SSW swell with a 19-second period and a light 10 km/h cross-shore breeze. It’s still not ideal, with a bit of crossing ripple, but the energy is high (2812). The afternoon is a touch bigger at 5.9 ft from the SW but with that same light cross-shore wind. It’s still marginal, but you might find a few if you’re keen.
Now, Friday the 14th. This is where it starts to get interesting. The morning is clean with a 4.9 ft SW swell and a 10 km/h offshore northerly. That’s a proper window. The afternoon though... wow. The wind drops to 5 km/h and goes glassy. We’ve got a 4.6 ft SW swell with a 15-second period and the combined energy is moderate (1188). The conditions are described as excellent for experienced surfers. This is your first standout. Get in the water Friday afternoon.
Saturday the 15th backslides. The swell drops to 4.3 ft and the wind swings around to a light cross-on from the SSE, leaving small wind ripples. The energy is weaker (811). Not worth the paddle.
Sunday the 16th is small. A 3.0 ft E swell with a very short period. The morning is clean with a light offshore, but there’s just no push. The afternoon is worse with a cross-on wind.
Monday the 17th brings a new pulse. The morning sees a 6.2 ft SW swell with a 13-second period and a light cross-shore breeze. It’s marginal, but there’s energy (1358). The afternoon goes glassy again, but the swell drops right off to 3.0 ft. That morning window might have a few.
Tuesday the 18th is a tale of two halves. The morning is a clean-ish 4.9 ft SW swell with a light cross-shore breeze. It’s surfable. But the afternoon? The swell pumps up to a massive 9.8 ft from the SW with a 12-second period. The wind is glassy. The combined energy is huge (2792). But here’s the thing – this break can’t handle that much size. It’s going to be too big and dangerous for anyone but the most experienced, and even then, it’s questionable. Keep an eye on it, but don’t get too excited.
Wednesday the 19th is still big but cleaner. The morning has 8.2 ft SW swell with a 12-second period and a clean offshore wind. That’s big and powerful (1866 energy), rated excellent for experienced surfers. The afternoon drops to a more manageable 5.9 ft with the same clean wind. This is a solid day for the crew who can handle it.
Thursday the 20th is a bit of a letdown. The wind goes onshore in the morning and picks up in the afternoon, killing the quality of the 5.2-5.9 ft SW swell.
Friday the 21st is another glass-off day. The morning has 5.2 ft SW swell with zero wind – glassy as

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.

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.
