The Lowdown

Alright, surfers, Rusty here. Let's have a look at what the ocean's got cookin' for us over the next couple of weeks at Jongensfontein. It’s a mixed bag, so let’s get into it.

The forecast starts off with a bit of a dud, to be honest. Friday the 4th and Saturday the 5th are looking pretty grim, with strong onshore winds and messy, poor surf conditions. The energy is there on Friday – we're talking moderate to strong energy with those readings around 1534 and 1242 – but it's all over the place and blown out. You can call it a write-off. We’ve got a clean slate for a couple of days there.

Sunday the 6th is a strange one. We've got a powerful, long-period SSW swell hitting – the combined energy is cranking at 5559 – but it's crossed up by a solid 28 mph east wind. It’s going to be big, maybe 8ft, but it’s going to be a messy, stormy mess. Not worth the paddle. Not for anyone.

The surf starts to settle down but stays marginal for a few days. Monday the 7th sees a drop in wind, but it's still cross-onshore, leaving the waves a bit lumpy. You're looking at waves around 6ft from the SSW, but it's going to be hard work for not much reward. Tuesday the 8th looks even less appealing – light winds but a weak, short-period E swell that just won't have any push to it.

Okay, now we're getting somewhere. Wednesday the 9th is the first sign of life. A light WSW cross-offshore wind and a clean 3ft SW swell. It’s small, but it’s clean, and the water is a normal 61°F for this time of year. That’s your glassy, small-wave option for those just wanting to get wet.

Now, Thursday the 10th is where it starts to get interesting. Overnight, a proper SW groundswell fills in. The morning is looking excellent – light cross-offshore winds, clean conditions, and the swell pushing 6ft with a 15-second period. That’s the kind of energy that makes a reef setup like Jongensfontein (Western Cape) come alive. The afternoon backs off a touch as the wind swings more cross-shore, but that Thursday morning window looks like the first real standout of the period.

Then we get slapped with another dose of reality. Friday the 11th and Saturday the 12th are blown out again, with strong SE to ESE winds ruining a decent-sized swell. Saturday especially is a washout, with 8ft of SSW swell and 28 mph winds – a complete mess. Sunday the 13th is similar, just a big, lumpy ocean, and by the afternoon it gets too big for the bay, with a 10ft cross-shore swell.

The following week is a real mixed bag. Monday the 14th has clean conditions but very little size. Tuesday and Wednesday are onshore slop. Then, just when you think it’s all over, the forecast for Thursday the 17th and Friday the 18th has some serious potential. Thursday morning brings a long-period SW groundswell with a fresh cross-offshore wind – still sizable at 6ft, but clean. That looks good.

But the big news is Friday the 18th. A massive S groundswell is forecast to roll in, with energy readings of 13036 – that's extremely strong. The swell is predicted at a solid 13ft. Now, the wind is looking offshore on Friday morning and by the afternoon it’s forecast to be glassy – absolutely zero wind. However, and this is a big however, a 13ft swell is not for the faint of heart. The data flags it as too big for this break. This is a day for experts only, and even then, it could be a washing machine out there. It’s promising, but that far out, you have to treat it as a potential monster, not a certainty.

So, to sum it all up: You've got a long, slow grind for the first week with a few brief windows of clean, small surf on the 9th and a better, more powerful window Thursday morning the 10th. The second week is where the real, goliath swells are lurking, with the 17th and especially the 18th being the potential highlights, but they come with a serious warning label: experts only.

This is Rusty, keeping an eye on the horizon for you.

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.
