The Lowdown
Alright folks, Rusty here, lookin’ at what we’ve got cookin’ for the next couple weeks around the Jongensfontein reef. It’s a mixed bag, so let’s ride through it.
The first half of this forecast period is a bit of a struggle. Plenty of swell energy kickin’ around – we’re talkin’ moderate to strong energy levels pushing 1326 through 2877 early on – but the wind just won’t play nice. Our spot, a south-facing reef that loves a clean S swell, is gettin’ hammered by cross-on and onshore breezes for days. Tuesday the 11th through to the Thursday the 13th are all write-offs: messy, lumpy, and cross-chopped. The water’s sitting at about 61°, which is pretty much normal for this time of year. Not too shabby, but you won’t be feelin’ it when the wind’s howlin’.
Then we get a little glimmer. Friday morning the 14th, the wind backs off and goes cross-offshore. That cleans the lines up nicely. We’re lookin’ at a 4ft groundswell from the SW with a beautiful 16-second period (long period, so reefs, points and rivers love this). The energy is moderate at 1217, and with that clean face, this is a proper window for experienced surfers. This is your first standout. Get on it early.
After that, things get a bit small and choppy again through the weekend and into Monday, with the swell droppin’ to under 3ft. We’re in a bit of a lull, but it’s not completely dead.
Now, keep your eyes peeled on Monday the 17th. Tuesday the 18th and Wednesday the 19th see a return of the SW groundswell, but wind becomes an issue again – cross-off on Tuesday keeps it clean but the gusts are fresh. The real gem waiting for us is deeper in the run.
Here’s the long-range promise: Friday the 21st of August is a serious standout. Morning session sees a 6ft SW groundswell, period at 12 seconds, and light cross-offshore wind from the west. Clean lines, solid energy (1154), and the conditions are rated excellent for experienced surfers. The following Saturday morning the 22nd holds similar potential, with 6ft SW swell and clean cross-off wind, though it’s a touch bigger in energy at 1476.
But if I’m picking one morning to circle on the calendar, it’s Tuesday the 25th of August and Wednesday the 26th of August. Tuesday morning has 6ft of SW swell with an offshore breeze – glassy, clean, and an energy reading of 1278 (moderate-strong). Wednesday the 26th? That’s even better: a 7ft SSW groundswell (a bit more size, still fine for experienced surfers) but with glassy conditions and a period of 12 seconds. That’s the kind of morning where the reef just comes alive. It’s a bit far out, but the signs are good.
Just remember, this is a consistent break but it’s a reef set-up, so longer period swells can make those waves stand up a bit more. And the crowds do show here sometimes, so bring your patience along with your board.
For kite surfers, there are days in this forecast where the cross-onshore winds and 5ft to 8ft sloppy swell look like more fun on a kite than a paddle, but for a real surfer, you wait for the clean windows.
That’s the long and short of it. Stay patient, pick your mornings, and I’ll see you out there on that reef.

Information about the Jongensfontein Surf forecast
The above surf forecast table for Jongensfontein provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jongensfontein can be found by selecting the local surf guide option on the grey menu. Our Jongensfontein 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 (Jongensfontein) 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 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. 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.
