The Lowdown
Alright, this is Rusty. Let’s have a look at what’s cookin’ for the next stretch.
The first few days are a write-off, mate. Wednesday and Thursday are just messy, with strong onshore winds and lumpy, poor surf. You’re better off stayin’ dry. Friday morning, the 14th, finally clears up and that’s where the real window opens.
Jongensfontein is a consistent reef break, and on Friday morning the 14th, we’ve got a clean, cross-offshore breeze with a 3.6ft SW groundswell running at a solid 16 seconds. That’s a long period groundswell, so the sets will be nice and lined up, with plenty of energy behind ‘em. The combined energy is moderate (1107), so it’s not a monster, but the shape should be excellent for experienced surfers. Water temp is sitting at 61°, which is about normal for this time of year. If you can get out there for that morning session, that’s the standout of the whole run.
Saturday and Sunday drop off again, with onshore wind and smaller, choppy surf. There’s a few clean windows on Monday the 17th morning and Tuesday the 18th morning, but the swell is weak and the period is short – around 13 seconds and 3.6ft to 4.3ft. It’s marginal, but you might find a fun little wave if you’re desperate.
The next real highlight is the morning of Thursday the 20th. The wind swings clean offshore, and we get a 5.2ft swell from the ESE, but the period is a short 8 seconds. That’s a windswell, so it’ll be a bit crumbly and less powerful, but the conditions will be clean. The combined energy is only 521, so it’s weak. Not a standout, but it’s a surfable morning.
After that, the second week looks pretty average. There’s a lot of onshore wind and choppy, poor surf. However, keep an eye on the mornings of the 25th, 26th, and 27th of August. The wind goes glassy, and the swell is tiny – 2.3ft to 2.9ft – but with absolutely no wind, it’ll be as clean as a whistle. The energy is weak (234 to 352), so it’s only for the longboard or a foiler, but if you want a glassy session, that’s your best bet that far out. Just remember, forecasts that far ahead are a little less certain.
So, bottom line: the best bet is Friday morning the 14th. Don’t sleep on it.

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.
