The Lowdown
Alright, Rusty here. Let’s break down what’s happening at Jongensfontein.
Right now, it’s a total washout. We’ve got a solid 11.5 ft SSW swell hitting Sunday afternoon, but a screaming 25 mph south wind is making it a messy, cross-onshore disaster. The wave energy is pumping at 2410, but you wouldn’t want to be out there. Monday and Tuesday are the same story – lumpy, cross-onshore, and no fun.
The first real chance comes Wednesday morning, 12 August, and Thursday morning, 13 August. The swell drops to 4.3 ft from the SW with a super long period of 19-20 seconds – that’s proper groundswell. The energy is strong (2657 on Thursday). Winds are moderate cross-shore, so it’s borderline, but the reef setup here loves that kind of long interval. The water’s at 61.3°, which is about average for the season.
Now, the standout window. Friday 14 August afternoon through Saturday 15 August morning is the real deal. On Friday afternoon, we’ve got 3.3 ft SW swell at 15 seconds with a light 3 mph cross-offshore breeze – clean as a whistle. The energy is moderate (820), but those conditions will make Jongensfontein (Western Cape) glassy and inviting. Saturday morning is even better: 3.3 ft SW, 14 seconds, and a glassy 3 mph offshore wind from the NNW. That’s about as perfect as it gets. The spot is consistent, so expect a few others in the water.
The next big one is a while off, but mark it. Sunday 23 August morning brings a 7.2 ft SSW swell at 16 seconds – that’s a very long period groundswell. The wind is glassy, and the combined energy is high at 2474. This is excellent for experienced surfers, but at 7.2 ft, beginners should stay on the beach. The reef will handle that long period nicely, but watch for the lulls between sets.
There’s a dry spell from 18 August to 22 August where the surf is mostly poor or marginal, with onshore winds and choppy water. Don’t expect much.
If you want the best, aim for Friday 14 August afternoon and Saturday 15 August morning for clean, glassy waves on the smaller side. And then Sunday 23 August morning for the bigger, long-period groundswell with perfect conditions – that’s the one to get excited about.
Stay salty.

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.
