The Lowdown
G’day, Rusty here, and I’ve had a proper look at what’s on the cards for Jongensfontein over the next couple of weeks. It’s a reef break that’s exposed to the south, and it’s consistent, but this forecast is a bit of a mixed bag with some real standouts if you time it right. The water temp is about average for the time of year, so nothing too wild there.
The first bit of the week is a write-off. Wednesday 26th is a mess with strong cross-onshore winds, and Thursday morning 27th is the first real whisper of hope. That Thursday morning kicks off with glassy conditions, a clean 6ft swell from the SSW at a long 12 seconds, and the combined energy is a strong 1272. It’s excellent for experienced surfers – the sort of session that’ll have you smiling. But Thursday afternoon gets a bit iffy with a light cross-shore, and then Friday and Saturday slide back into poor surf.
Sunday 30th and Monday 31st have some small windows. Monday morning 31st is glassy with a 4ft SW swell at 12 seconds, and the energy is a moderate 394. It’s clean, but nothing to get too excited about.
Now, here’s the big one. Tuesday 1st September is a standout. The morning session has a massive 10ft swell from the SW with a 15-second period and a very strong energy of 4144. The wind is cross-offshore and clean, but this is too big for this break – definitely for experts only, and even then, it’s a beast. The same goes for Wednesday 2nd September morning. These are big, powerful, long-period swells, and at a reef break, they’ll be heaving but mighty dangerous. For the average surfer, it’s a day to watch.
After that, there’s a bit of a gap with poor conditions and strong cross-onshore winds through the first week of September. The swell drops and the wind chops it up.
Then, on Sunday 6th September, there’s a decent looking morning. A 6ft swell from the ESE at 12 seconds with a moderate energy of 1408, and cross-offshore winds from the north making it clean. It’s excellent for experienced surfers. That’s your second highlight.
The tail end of the window, on Thursday 10th September, offers a small, clean morning with a 2ft SE swell at 12 seconds and light wind. It’s glassy, but the energy is weak at 270. A quiet session for the longboard.
So, the best on offer is the Thursday 27th August morning for a quality, clean session, and the big Tuesday 1st September morning if you’re an expert chasing a serious challenge. The rest is a lot of waiting for the wind to play ball.
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.
