The Lowdown
Listen up, team. Rusty here, and I’ve been digging through the charts for our little slice of coast. It’s a 16-day run with some real juice and some proper duds. Don’t rush into it – the first few days are a bust.
The one to circle is Sunday morning, August 23rd. Hit Jongensfontein – this reef break is consistent and it’s gonna be firing. The water’s at 61°F, right where it should be for this time of year, so nothing weird there. We’re looking at a solid 6ft swell out of the SW with a 12-second period – that’s proper groundswell, the kind that lines up. And the wind? Dead calm, glassy. Moderate wave energy (841), and the swell direction is spot on for the spot. This is your session.
Monday the 24th morning is still worth a look. Smaller at 4ft from the SW, but with a light cross-off breeze keeping it clean. The energy drops a bit (529), so it’s a fun, smaller day on a mid-length.
Tuesday the 25th gets bigger – 8ft SW swell with a 14-second period. That’s a lot of water and strong energy (2020). But the wind goes cross-on, and it’s only marginal with small ripples. Maybe one for the experienced crew only.
Wednesday and Thursday (26th and 27th) are a mess. Strong easterly winds at 28 mph blow everything out. The swell’s still there with strong energy (2130 on Wednesday), but the wind is ruining it. Honestly, I’d look at this as a kite session more than a paddle session.
Friday the 28th is a write-off, and Saturday the 29th morning has a cross-off wind that cleans it up, but the swell period is short (9 seconds) and energy is moderate (708). Not worth it. That afternoon, the swell hits 10ft – too big for this break. Experts only.
Sunday the 30th has an 8ft SW swell with a decent period, but cross-on winds and strong energy (1767) make it marginal.
Monday the 31st morning has a 6ft SW swell with a clean cross-off wind – that’s a sneaky good session with moderate energy (677).
The long-range promise is Sunday, September 6th. That morning it’s flat calm – glassy, with a 8ft SW swell and a 13-second period. Energy is strong (1937), and the forecast says excellent for experienced surfers. It’s two weeks out, so don’t bank on it, but if it holds, it’s a beauty.
So, your standout is Sunday morning, August 23rd at Jongensfontein. Glassy, clean, and a solid SW groundswell. Second look is Monday the 24th morning, and keep an eye on that 6th of September.
Rusty, out.

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.
