The Lowdown

G’day, it’s Rusty. We’ve got a solid run of surf lining up at Jongensfontein over the next couple of weeks, with some real juice on offer. The wave energy builds from moderate through to strong, and with a consistent S to SW swell direction hitting this exposed reef, the setup is looking good for experienced crew. Water temp is sitting at 60°F, pretty normal for this time of year.

Monday morning the 17th kicks things off nicely. Clean 5ft SW swell with a long 13-second period, light WNW cross-off breeze – that’s a proper combo for a reef like this. The combined energy is moderate at 930. It’s a solid start, but there’s better to come.

Tuesday the 18th is a bit of a mixed bag. The morning has a cleaner 6ft SW swell at 13 seconds, but the wind swings cross, and the energy jumps to 1124. Still rideable, though not the pick. By Tuesday afternoon, the swell pushes 8ft from the SW, but it’s onshore from the ESE, so it’s messy.

Wednesday the 19th morning is a standout for experienced surfers. Clean, 7ft SW groundswell at 12 seconds, light W cross-off winds, and the energy is strong at 1445. The waves will have shape and power, but that size means it’s not for beginners.

Thursday the 20th brings the biggest swell of the first week. Morning sees a whopping 12ft SSW swell with a 13-second period – combined energy is very strong at 3735. The wind is light and cross-off, but that’s way too big for this break, even for experts. Only the most hardcore might paddle out. Afternoon is similar with 10ft SW, but onshore wind makes it a no-go.

Friday the 21st drops back to 6ft SSW, but it’s onshore – poor conditions, not worth it.

Saturday the 22nd morning offers a decent 6ft SW swell with light WNW cross-off and 717 energy. It’s clean, but the real action is later. Tuesday the 25th morning is a true highlight. Glassy conditions with zero wind, a 7ft SW groundswell rolling in at a long 13 seconds, and strong energy of 1613. This is the best session of the whole window – clean, powerful, and lined up on the reef. Crowds are possible here, so get in early.

The end of the month sees a huge surge again. Monday the 31st has 10ft SW swell with a very long 16-second period – energy is extreme at 4319 – but with persistent cross-onshore winds and rain, conditions are poor. That same massive energy lingers into September 1st, but again winds are messy. The reef won’t be clean, and the size is only for the brave.

Overall, there are gaps of a few poor days here and there, especially around the 21st and the very end. The standout is Tuesday 25th morning – glassy, substantial swell, long period, and clean. Next best is Wednesday 19th morning. The rest is a mix of good and ordinary, but those two windows are the ones to circle.

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.
