The Lowdown
Alright, Rusty here, let’s talk about what’s cooking for the next couple of weeks.
Overall, it’s a mixed bag at best. The first few days are pretty average, and we’ve got a long stretch of messy, blown-out conditions coming up. The standout window is narrow, but there is a moment where it all comes together.
Tuesday 15th September Morning is the pick of the early period. The swell drops to a manageable 5ft from the East, with a clean WNW offshore breeze of just 9 mph. That’s a proper clean window at Jongensfontein. The energy is moderate (629), but with that wind, it’ll be smooth and lined up. It’s a reef, consistent, and when it’s offshore like this, the waves will have some real shape. The water temp is 62°, which is bang on average for this time of year, nothing unusual there.
The next sniff of decent surf is Monday 21st September Morning. We see a 6ft Southeasterly swell, but the wind is a light WSW cross-off at 6 mph, which will keep things clean. The energy is moderate (1186), and while the crowd factor at Jongensfontein can be “sometimes” busy, on a Monday morning you might get a few less people out. This one is aimed at experienced surfers though – the conditions are marked as excellent but for the more skilled crew.
After that, the second week trails off into a lot of onshore wind and choppy, blown-out conditions, with plenty of strong winds and energy in the water, but no quality for a paddle surfer. Between the 15th and the 21st there’s a long gap of poor surf, and the last week is mostly marginal or poor, so don’t hold your breath too long.
Best on offer: Tuesday 15th September morning for the clean offshore glass. The back-up is Monday 21st September morning if you can handle a bit more size and a cross-off breeze.

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.
