The Lowdown
Alright folks, Rusty here with a look at what the ocean's got cookin’ for us.
Overall, we’ve got a bit of a mixed bag over the next couple of weeks. We start with some half-decent, but flawed, conditions before things clean right up for a classic, glassy winter’s day. But don’t get too comfy, because after that, a whole lot of wind and some truly monstrous, dangerous swell rolls in. The back half of the window is pretty much a write-off for us.
Our one and only spot on the menu is Jongensfontein, a consistent reef break that likes a good south swell.
Monday (24th) & Tuesday (25th) are a bit of a tease. We see some waist to chest-high swell around 4ft to 6ft coming from the southwest. The energy is building from moderate to strong (maxing out at 1911), with a decent 11 to 13-second period, so there’s some push there. But the wind is on it, keeping things choppy and messy. You might find a corner, but it’s not one to get excited about.
Now, Thursday morning (27th) is the real standout. This is the one we wait for. The wind drops right out to glassy – dead calm – and the water turns to glass. We’ve got a clean 5ft to 6ft southwest groundswell with a 12-second period and strong energy in the water (around 1296). This is a setup made for Jongensfontein. The reef will be working, the waves will have shape, and the paddling out will be a breeze with those longer lulls. For a confident intermediate, grab a board and go. This is the best of the whole run.
Friday (28th) turns ugly fast. The wind swings onshore and whips up to a lumpy 19 mph, killing the quality. The swell shifts easterly and drops in period to 10 seconds, and combined with the onshore wind, it’s just a messy, choppy affair. Give it a miss.
Saturday (29th) is a wild card that goes from bad to insane. The morning is small and weak. But by the afternoon, the swell rockets up to a massive 10ft. The problem is, that’s way too much juice for this break. It’s a clean, big, and dangerous wash-through. Leave this one to the tow teams or the lunatics. For a regular surfer, this is a no-go zone.
From Sunday (30th) all the way through to Monday (7th September), the outlook is poor. We’re talking relentless onshore winds and big, unruly swell. The water gets churned up with a lot of rain showers. There are a few days where the swell gets comically large – hitting 18ft on Thursday 3rd September with 17-second periods and energy readings over 17887. That's not surf, that's a survival event. For the rest of us, it’s a solid break from the ocean.
There is a little flicker at the very end on Tuesday morning (8th September). The wind goes clean offshore and the swell drops to a manageable 4ft, but the period is a short 7 seconds. It could be a fun little session for a longboard or a fish if you’re jonesing, but it’s not the main event.
So, to sum it up: Your window is Thursday morning (27th). That’s the one. After that, sit back, watch the ocean rage, and wait for the next calm.
Rusty.

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.
