The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming for Jongensfontein in feet and knots.
First week is a tough one, I won’t lie. From Sunday the 13th through Friday the 18th, it’s mostly cross-onshore or onshore winds, making the ocean lumpy and choppy. Water temp is about average for this time of year, nothing to write home about. But the wind is a real buzzkill.
The first real chance to get wet is the morning of Tuesday the 15th of September. Light offshore wind from the NW, clean 5-foot swell out of the east with an 11-second period. Wave energy is moderate. It’s a short window, but that’s the best looking session in the first week.
After that, we’re back to messy conditions until the very end of the forecast. Monday the 28th of September is the big one. We’re talking a solid 10-foot swell from the SW, with a 13-second period, and light cross-offshore wind from the west – that’s going to be glassy. The wave energy is strong. Now, this is a big swell – over 8 feet, so it’s for experienced surfers only. Beginners, stay on the beach. For the crew that knows what they’re doing, this reef break at Jongensfontein (South Africa) could be absolutely pumping. The swell direction is perfect for this spot, and with light winds, it’s about as clean as it gets. Crowds are possible, so you might have to share.
Between the 16th and the 27th, there are some days with swell, but the wind is almost always cross-on or onshore, ruining the quality. Some of those days have long periods (over 15 seconds), which can make for some drawn-out lines, but with the wind blowing messy, it’s not worth it.
So here’s the bottom line: the first week is mostly a no-go. Your best bet is the morning of Tuesday the 15th for a quick clean session, but the real prize is waiting for Monday the 28th of September. That’s the day to have on your radar. It’s a ways out, so keep checking the forecast, but right now it’s the only true standout.
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.
