The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for our local stretch.
The coming weeks are a mixed bag, with a lot of onshore wind and messy conditions, but there are a few moments that’ll get the heart rate up. The standout window is definitely the second week, with a couple of days that look exceptional for experienced surfers.
Right now, the water temp is sitting at 62°, which is about average for the time of year, so no surprises there.
Tuesday, 4 August kicks things off with a little 4ft swell from the ESE, period of 10 seconds, and a light cross-offshore breeze in the morning. The combined energy is moderate at 611, and it’s clean. That’s a nice little session for intermediates, but the swell drops off and the wind turns messy in the afternoon.
Wednesday, 5 August sees a new pulse of SW groundswell. The morning has 5ft, a very long period of 16 seconds, and light cross-shore wind. The combined energy jumps to 1475. That’s a solid, powerful swell, but it’s a bit all over the place with the wind, so while the raw energy is there, it’s not the cleanest.
Thursday, 6 August and Friday, 7 August get bigger but the wind is cross-onshore and choppy. The swell is 8ft and 8ft, with periods around 13-14 seconds, but the wind is a problem. Friday afternoon actually has a 10ft SW swell with 16-second period and an onshore wind, but the combination of size and wind is a no-go for paddle surfing.
Saturday, 8 August is a bit of a tease. The morning has a clean 8ft SW swell with a cross-offshore breeze, but the wind is a moderate 16 mph, so it’s not glassy. The swell energy is strong at 1915.
Sunday, 9 August and Monday, 10 August are a total write-off. Strong winds, big messy swell, and poor conditions. The combined energy hits 3089 and 3784, but it’s all wind-blown junk. Definitely not a weekend for the surfboard.
Tuesday, 11 August is still fresh and lumpy, nothing to write home about.
Now, here’s where it gets interesting. Wednesday, 12 August morning: a clean 8ft ESE swell, period of 12 seconds, with a cross-offshore breeze. The combined energy is massive at 4914. That’s a lot of power, but it’s a bit on the big side – better for more experienced crew.
Thursday, 13 August is the true standout. The morning has a 10ft ESE swell, 14-second period, and cross-offshore wind, but it’s the afternoon that’s gold: glassy conditions, 8ft ESE swell, 14-second period, and a combined energy of 4245. That’s excellent, powerful, clean surf for experienced surfers. This is the one to circle on the calendar.
Friday, 14 August morning is still good – clean 7ft ESE swell, 12-second period, with a gentle cross-offshore breeze. Energy is 2062. A solid session.
After that, the swell backs off. Saturday, 15 August and Sunday, 16 August have smaller ESE swell, dropping to 3ft, and wind is mostly onshore or cross. The energy drops to 310 by Sunday morning. It’s a quiet end to the period.
Monday, 17 August and Tuesday, 18 August bring a fresh SW swell, but the wind is strong and cross-shore, so it’s messy again. The energy is high, but it’s not surfable in a clean way.
So, the best on offer is hands down the Thursday, 13 August afternoon session at Jongensfontein. Glossy, powerful, and clean. The Wednesday morning and Friday morning are also decent. The rest of the time, you’re fighting the wind or the size.
Rusty signing off.

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.
