The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the way for Jongensfontein, but you’ll have to be patient and pick your moments. The wind is going to be the main character here, and it’s not always gonna be on our side.

The first real chance to wet a line is Thursday morning, the 13th of August. There’s a big 5.6ft SW groundswell with a super long 18-second period showing up. That’s a lot of energy (4061). The water is sitting at 60.8°, which is pretty much normal for this time of year, so no surprises there. The problem is the wind is coming from the NE at 9 mph, putting it cross-shore, so the surface will have a bit of chop. It’s surfable, but it’s not the cleanest start. The afternoon drops a touch in size to 5.2ft, but the wind goes light cross-onshore, so it’s still a bit messy.

Now, Friday morning the 14th is where things get interesting. The swell has backed off to 3.6ft, but the wind swings to the WNW at 9 mph, which is offshore. That’s the golden ticket. It’ll be clean and lined up, perfect for an intermediate surfer to have a blast. The energy is down to 1054, but the quality will be there. This is a standout morning if you can get out. The afternoon turns ugly, though – a strong SSW wind at 12 mph puts it onshore and choppy, so don’t bother.

The weekend is a write-off. Saturday and Sunday are either cross-onshore or too light, with the swell dropping below 3ft. Not worth a paddle.

Monday the 17th shows a bit of life again with 4.6ft SW swell, but the wind is light and cross-onshore, so it’s marginal. The morning of Tuesday the 18th is better – the wind goes cross-offshore from the west at 9 mph, with 4.3ft of swell. It’s clean, but the energy is only 588, so it’s a smaller, mellower session. The afternoon gets wrecked by a 19 mph cross-shore wind.

We’ve got a bit of a gap then. Wednesday and Thursday the 19th and 20th see the swell bump up to 5.9ft – 6.6ft, but the wind is onshore or cross-onshore, making it choppy and tough. The energy is moderate to strong (up to 1142), but the wind just kills it.

Look ahead to Saturday the 22nd. The morning brings a solid 7.9ft SW swell with a 14-second period and a strong cross-offshore wind from the WSW at 16 mph. The energy is pumping at 2298. This is big, powerful, and clean. It’s only for experienced surfers at this size – over 8ft is expert territory, but 7.9ft is still a serious step up. The afternoon drops to 6.9ft but the wind goes cross-shore, so it’s not as clean.

Sunday the 23rd is a step down, with 5.9ft and a light cross-shore wind, but the afternoon gets blown out again.

The real standout for the long range is Thursday the 27th. The afternoon shows a 7.9ft SW swell with a 15-second period – that’s a very long period groundswell, meaning heaps of energy (2529) and long, clean lines. The wind is a light cross-onshore from the SSE at 6 mph, which is almost glassy. This is the biggest and cleanest setup of the whole 16 days, but it’s still over a week away, so keep an eye on it. The period is so long that at a beach break, it might get a bit straight, but at a reef setup like this, it’ll be world-class.

Also, Friday the 28th morning is worth a mention – 7.5ft SW swell, 14-second period, and a light cross-shore wind from the SW at just 3 mph. Another clean, solid day.

Overall, the best two windows are Friday morning the 14th for a clean, smaller session, and Thursday the 27th afternoon for the big, long-period, near-perfect stuff. The crowds at Jongensfontein can be a thing sometimes, so get out early for the clean ones.

Stay stoked.

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.
