The Lowdown
Alright, let’s break down what’s happening around Jongensfontein for the next couple weeks.
First thing – we got a dry spell before anything good shows up. Right now on Monday afternoon, it’s no good. You’re lookin’ at 4ft of SW swell, cross-on S wind at 6 mph, and the energy is weak (469). Total mess. Don’t bother.
Now, Tuesday morning the 1st of September is the real deal. That’s the one to aim for. The reef at Jongensfontein is gonna be clean with a solid 8ft SW groundswell, 13 second period, and glassy wind from the WSW at just 3 mph. The combined energy is strong at 1754. For intermediate surfers, that’s as good as it gets. Water temp is 61°, which is pretty average for this time of year, nothing wild. This is a morning session you do not wanna miss.
Tuesday afternoon the wind picks up and it gets choppy, so the window’s short. Wednesday morning the 2nd is glassy again with similar size – 8ft SW swell, same 13 second period, and strong energy at 2079. Another excellent window for the experienced crew before the onshore wind wrecks it in the afternoon.
From Wednesday lunchtime onward, it’s a long, ugly stretch. Thursday the 3rd brings rain and dropping swell. Friday through the weekend is hammered by strong onshore winds – 25 to 34 mph – and big messy surf up to 12ft. That’s kiteboarding weather, not surfing. The whole first week of September is pretty much a bust after Wednesday morning.
We do get a little glimmer on Tuesday the 8th of September. Morning session has a clean 8ft ESE swell with a cross-offshore N wind at 12 mph – marginal but doable. Then Tuesday afternoon goes glassy again with 6ft ESE swell, 10 second period, energy at 742. A nice little evening wave if you don’t mind smaller surf.
After that, the second week fades hard. Swell drops, winds get messy. The last decent look is Thursday the 10th with a small 4ft SW groundswell, 12 second period, and clean cross-offshore wind in the morning – but it’s still only marginal. From the 11th onward it’s mostly poor all the way through the 15th. The long-range stuff on the 15th shows some size (5ft, 14 seconds, SW) but the wind is too strong and cross-shore to call it good.
So if you’re around Jongensfontein, lock in Tuesday morning and Wednesday morning of the 1st and 2nd of September. After that, the second week is quiet and unreliable.
Stay wet, stay keen.

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.

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.
