The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks.
We’re gonna have a bit of a wait for the good stuff, but it’s worth it. The opening window is Monday morning, 31 August, and it’s a real treat. Jongensfontein is glassy, with a clean 5 ft SW swell at 11 seconds. The water’s sitting at 61°, which is pretty much bang on what you’d expect for this time of year. The combined energy is moderate at 524. It’s a reef set-up, so it’s got that nice shape to it, and with a light offshore, it’s going to be clean and lined up. This is the pick of the first week for sure.
Monday afternoon, the wind swings and it gets messy, so don’t bother.
Now, Tuesday morning, 1 September, is a big one. The swell jumps to 8 ft from the SW, with a solid 13-second period and a combined energy of 1754 – that’s strong. Glassy conditions again. This is proper groundswell, and for an exposed reef like Jongensfontein, that’s going to produce some serious, long-period lines. It’s big, so only for experienced surfers, but if you’ve got the skill, this is the standout. The wind stays light and clean.
Wednesday morning, 2 September, is more of the same. Another 8 ft SW swell, 13 seconds, glassy, and very strong energy at 2079. It’s still only for the experienced crew, but the quality is undeniable.
Then things go to hell. From Thursday afternoon, 3 September, right through to the end of the first week and into the second, it’s a write-off. Strong onshore winds, huge messy swell, and rain. There’s a big gap of poor conditions from the 3rd through to the 8th of September. Not worth the drive.
There’s a glimmer on Wednesday morning, 9 September, with a small 4 ft E swell, 9 seconds, and a light offshore. The energy is weak at 305, but it’s clean. It’s a beach day, not a proper surf day.
Thursday morning, 10 September, is glassy again but tiny, with only 3 ft at 8 seconds and combined energy of 166. Surfable, but very ordinary.
The real standout of the second week is Sunday morning, 13 September. A solid 8 ft WSW swell, 10 seconds, with a clean cross-offshore wind. Combined energy is strong at 1794. This is a proper swell, and with the wind off the land, it’s going to be clean and powerful. Only for the experienced. It’s a long way out, but it looks promising.
After that, the wind gets messy again, and the surf drops off. So, to sum it up: Monday morning the 31st and Tuesday morning the 1st are your best bets for the first week. The second week, keep an eye on Sunday morning the 13th.

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.
