The Lowdown
Alright, grab your wetties, let's have a look at what's coming down the line at Jongensfontein. This reef set-up is consistently exposed to the south swell, which is the key to unlock it.
We’re looking at a classic South African winter pattern. Water temps are sitting around 62°, which is bang on average for this time of year – nothing out of the ordinary there, just a standard winter wetsuit job.
The standout window for this break is the early part of the forecast. Tuesday morning, the 25th of August, is your best bet. We've got a solid 6ft SW groundswell with a long 13-second period rolling in, and the combined energy is nice and chunky at 1911 (moderate wave energy). The wind is dead glassy from the NE, so those waves will be as clean as a whistle. It’ll be a bit heavy for beginners with that size, but for anyone with a bit of experience, this is the session to circle. Crowds are a "sometimes" thing here, so you might get it with a few mates.
Tuesday afternoon the wind swings onshore and everything turns to chop.
Wednesday the 26th gets smoked by a 28 mph cross-onshore gale. Forget about it.
Now, Thursday morning, the 27th of August, is your second highlight. The glassy WNW wind returns with a 6ft SW swell and a 12-second period (combined energy of 1282 – moderate). That’s another window of clean, lined-up waves for the experienced crew. Thursday afternoon, the wind goes light cross-onshore and the quality drops off, but the morning session is the one.
Friday morning, the 28th of August, is a nice little morning option. The swell drops a touch to 4ft from the south, period 11 seconds (combined energy of 690 – weaker), and you’ve got that glassy SSE wind again. Clean conditions, but it won’t have the grunt of Tuesday or Thursday.
After that, Saturday (29th) and Sunday (30th) are a write-off – messy, onshore winds or small, weak waves. There’s a gap here for a few days with no solid recommendations.
Now, looking at the second week, things get proper heavy. From the 1st of September onwards, the swell really starts to crank up, but it gets too big for comfort. Tuesday the 1st and Wednesday the 2nd are looking at an 12ft swell, and the combined energy on the 2nd is a massive 4916 (strong). That’s expert territory only. The wind is offshore on those days, so the reef will be showing some very serious, clean faces, but you’ll need to know what you’re doing.
The 4th of September is even bigger. We’re talking an 18ft SE swell with combined energy hitting 7694 (very strong). The wind is light and cross-shore, but that size at this reef setup is going to be a washing machine for anyone not absolutely dialled in. This is more of a big-wave tow-in or a spectator sport kind of day.
Overall, don't mess around with the afternoons. Stick to the glassy mornings for the cleanest rides. The standout is clearly Tuesday morning the 25th of August for that perfect combo of size, period, and wind.

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.
