The Lowdown
Alright crew, Rusty here with the long-range picture for the next couple of weeks. Let’s get into it.
We’re starting off on a rough note. The first few days are a total washout for any decent paddling. Saturday the 5th and Sunday the 6th are blown to bits – fresh to strong cross-onshore winds wrecking a solid SSW swell. The wave energy is significant, sitting at values over 5000, but the wind makes it impossible to surf. You’d just be getting rag-dolled.
Monday the 7th through Wednesday the 9th is still poor. Swell drops, but the onshore and cross-shore winds keep the ocean lumpy and choppy. The combined energy dips into the weak 300-600 range. It’s a waiting game, plain and simple.
Thursday the 10th and Friday the 11th see a bigger SW swell push in, with combined energy around 1000-2000, but the wind is still onshore. The data calls it “marginal,” so there’s size but no quality yet.
Now here’s the real standout: Sunday the 20th of September. This one gets me excited. A solid 3.5m SSW swell is forecast, and here’s the kicker – the wind is glassy in the morning with a light NW breeze. The combined wave energy is cranked up to 3416, and with a very long 12-second period, this is a proper groundswell. The break is Jongensfontein, a reef setup, so that long-period energy will line up beautifully. But listen, at over 2.5m, this is strictly for the experienced surfer. Beginners, sit this one out.
There’s also a nice little window on Monday the 15th of September. The morning offers 1.9m of SW groundswell (11-second period, combined energy 1017) with a light WNW cross-offshore breeze. The data says it’s “excellent surf conditions for experienced surfers.” It’ll be clean, well-shaped, and a lot of fun for the right crew.
The rest of the second week is messy with a lot of wind and chop. Focus on Sunday the 20th for the biggest and cleanest waves. The water temp is sitting at 16°, which is just about average for this time of year, so nothing unusual there.
Stay safe out there, and I’ll see you in the water.

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.
