The Lowdown

Alright folks, let's get into it. Overall, the next 16 days are looking pretty ordinary out at Jongensfontein. There’s a lot of wind and messy conditions on the way, and only a couple of short windows that look any good. We’ve got a big gap of rough stuff to sit through before we see anything clean.

Right now and through this first weekend, it’s a write-off. Friday morning starts with a marginal 4ft SW swell (907 combined energy), but that ESE wind at 6 mph is already on it, and the tide's not playing nice. By the afternoon the wind cranks up to 19 mph, and it’s all downhill from there. Saturday and Sunday are purely for the windsurfers. We’re looking at waves from 5ft to a massive 12ft, but with howling onshore and cross-onshore winds over 25 mph, it’s just a mess.

Monday doesn’t offer much relief either. It’s still messy, with moderate cross-shore wind and a bit of cross-chop. The surf stays around 7ft to 8ft, but the conditions are marginal at best.

Then, we finally get a little window. Tuesday morning, the 15th of September, is the first standout in this whole run. The wind swings light WSW at 6 mph, coming cross-offshore, cleaning things right up. We’ve got a 5ft swell from the east (11 seconds of period, 1218 combined energy). It’s clean, and the conditions are excellent for experienced surfers. This is the best session on offer in the first week, but you’ll want some skill under your belt.

After that, it’s back into the blender. Wednesday through the rest of the week and into the next weekend is plagued by moderate to fresh cross-onshore winds, choppy and lumpy surf, and nothing worth paddling out for.

Now, here’s the second standout, and it’s a long way off. The morning of Monday, the 21st of September, is easily the most promising day in the whole outlook. It’s glassy. Dead flat calm, with an ESE breeze at just 3 mph coming right onshore but so light it’s glassy. The swell is a clean 5ft from the SSW (12 seconds, 1078 combined energy). This is a rare, clean moment. Again, this is for experienced surfers. Mark it in your calendar, but keep an eye on the forecasts because it’s a long way out.

Up until the 26th, things then go back to poor, with strong to near-gale winds and lumpy conditions. A few days around the 24th show some bigger SW swell (7ft to 8ft) and moderate cross-shore wind, but it’s just not clean enough to get excited about.

So, to wrap it up: the water temp is about 63°, which is pretty normal for this time of year. There's no real stand-out reason to go looking for crowds at Jongensfontein, but if you want a clean wave, Tuesday the 15th morning and Monday the 21st morning are your only real shots. Hang in there.

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.
