The Lowdown
G’day, it’s Rusty. We’ve got a solid 16-day window ahead of us, but don’t get too fired up just yet – the first week is mostly a write-off with messy wind and onshore slop. The good stuff starts to show late in the second week, with a couple of days that look genuinely special.
Alright, let’s start with the only break on the cards: Jongensfontein. It’s a consistent reef setup, exposed to S swell, and the optimum swell direction is S, so when the wind plays nice, it can be magic.
The early part is grim. Friday the 7th morning is already cross and lumpy with 8ft SW swell at 15 seconds and a fresh ENE breeze – not worth paddling out. The whole first week, from Friday the 7th right through to Monday the 10th and Tuesday the 11th, is plagued by onshore winds or funky cross-chop. Swell sits around 5ft to 8ft, but the wind state is just poor. You’ll see a few days where the combined swell energy is strong (2510 to 3432) but it’s all blown out. Tuesday the 11th afternoon is particularly messy with a 25 mph E wind and only 5ft swell – skip it.
Wednesday the 12th and Thursday the 13th start to show a flicker. Wednesday morning has a 4ft SW groundswell at 20 seconds, but a fresh cross-shore messes it up. Thursday the 13th morning is where it gets interesting: the wind turns light NNE cross-off, 6ft SW swell at 18 seconds (very long period), and the combined energy is 2479. The water temp is about average for this time of year at 62°, nothing unusual. This is a legit session for experienced surfers – that long-period groundswell will wall up nicely on the reef. Just be aware that crowds are possible here.
There’s a bit of a lull from Friday the 14th into Saturday the 15th – smaller swell, dropping to 4ft to 4ft, but the wind stays light and clean. Saturday morning with 4ft SW at 15 seconds and a light N breeze is a solid pick for a fun, uncrowded session.
Now, the standout. Monday the 17th morning is the one to circle. Light offshore wind from the NW, 6ft SW swell at 14 seconds, combined energy of 1124 – this is excellent, clean surfing for experienced surfers. It’s not too big, it’s not too small, and the reef will shape it up beautifully.
Friday the 21st is a beast, but with a big caveat. Morning has a 8ft WSW swell at 11 seconds and cross-off wind – clean but solid. The afternoon though, is huge: 10ft SW swell at 12 seconds, clean cross-off, and combined energy of 2247. The file says this is predicted to be too big for the break. That is expert-only territory, and even then, it could be washing through.
The final weekend, Saturday the 22nd, goes back to rain showers and strong cross-shore slop – best to stay home.
So, the real highlights: Thursday the 13th morning and Monday the 17th morning. Both offer clean, long-period SW groundswell with light to offshore wind, perfect for a reef set-up. The rest of the window is mostly frustrating – a lot of energy but wrong wind.
Stay patient, and keep an eye on that second week.

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.
