The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at the 16-day picture for our local patch.
Right off the bat, I gotta be straight with you – the first week and a half is a real struggle. We’ve got a nasty run of strong cross-onshore winds that are just tearing the place up. From Monday the 10th right through to the middle of the month, it’s a write-off. The wind is howling from the SSE and SE at 18 to 25 mph, and the swell is bumpy and lumpy. Even when the swell gets some size, the wind is just ruining it. There’s a solid 7ft to 8ft S/SSE swell running on Monday and Tuesday, but the combined energy is high, and it’s all for nothing with that wind. It’s a total mess.
We finally get a little window of hope on Friday the 14th afternoon. The wind drops right out to glassy, and the swell is a clean 4ft from the SW with a 15-second period. That’s a proper groundswell, and with the glassy conditions, it’s the best we’ve seen all week. The energy is moderate, but it’s clean. That’s the highlight of the first week, but it’s a small window.
The weekend (15th and 16th) is back to marginal, with the swell dropping to 2ft–3ft. Clean enough in the mornings, but small and weak.
Now, the real standout is way out there, but it’s worth the wait. On Friday the 21st of August, we’ve got a big 10ft ESE swell rolling in. The wind is offshore from the W at just 3 mph, and the conditions are clean. Now, this is a big one. The combined energy is very strong, and the period is 11 seconds. This is for experienced surfers only – it’s too big for beginners. This is the best swell on offer by a long shot.
Then, the following Saturday and Sunday mornings (22nd and 23rd) are glassy too, with a 4ft–5ft SW groundswell (period 15–17 seconds). The energy is strong, and the conditions are excellent for experienced surfers. The long period will make for some proper waves, but at a reef break, it’ll be a good thing.
So, the long and short of it: the first week is a write-off. The best surf is the Friday the 21st big swell, and then the last weekend of the month looks promising. Keep your eyes on the forecast.
Rusty.

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 Jongensfontein 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.
