The Lowdown

G’day, it’s Rusty here.

Alright, let’s get into it. The next week and a half or so is a bit of a mixed bag for our stretch, with a few windows of real quality buried in a pile of onshore slop. The real standout is a window approaching on the first of September. The pick of the bunch is Jongensfontein.

Water temp is 61°, which is about normal for this time of year. The first few days are pretty forgettable. Sunday the 30th has a bit of swell, but the cross-offshore winds and an 11-second period will have it looking messy, with only a 6ft swell on offer. The energy is weak enough at 963. Not worth paddling out for. Monday the 31st fades a bit, dropping to 5ft, and it keeps that messy, cross-shore ripple look. Still nothing doing.

Now, here’s where it gets interesting. Tuesday morning, the 1st of September, is the one to circle. The swell jumps to a solid 8ft, bumping up from the southwest with a nice, long 13-second period, and the combined energy jumps to 1835 – that’s a proper pulse. Winds are light and cross-offshore, with that clean look to it. This is the best of the week. It’s a reef break, and while it’s mainly middle-of-the-road, this is cleaner and more powerful than anything else we’ve seen. The afternoon before it gets a bit bigger (8ft) but the breeze swings around and gets it messy, so you’ll want to make your move in the morning. That 8ft in the afternoon is getting into expert territory, but 8ft in the morning is still a great, powerful wave.

After that, it’s a letdown. Wednesday has some size but the E wind is straight on and ruining it. Thursday the 3rd has some clean morning windows with 5ft so you might get a fun one in before the wind, but that afternoon brings a 15ft pulse with a strong S wind, so the ocean turns into a washing machine. Forget it.

The following few days are a proper write-off. The wind goes easterly and it’s cross-onshore and breezy, making it messy and lumpy. Even with a few longer period swells from the southwest, the south-east and east winds blow everything out. No point even looking at it until the 10th, really.

Thursday the 10th of September has another chance. It drops back to 6ft, but the wind finally drops out and goes light cross-offshore. It’s clean again. It won’t have the grunt of the 1st, but it’s fun and clean. That’s a good one for the longboard or a groveler.

Then it gets ordinary again for a stretch as the wind comes onshore and the swells get short and weak, with a couple of low-energy, short-period SE pulses. The last real thing to note is the 14th of September. The morning is glassy, with a solid 10ft ESE swell, but that’s too much water moving through here, and the break just won’t handle it. It’s only for the very brave, and even then, it could be a washing machine. Better to watch that one from the beach.

So, the two standouts are the morning of Tuesday the 1st of September, and to a lesser degree, the morning of Thursday the 10th. Get in the water before the wind gets up. It’s a good reef, and when it’s on, it’s on. There’s a bit of a lull for a few days either side, but that first Tuesday looks like the pick of the whole fortnight.

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.
