The Lowdown
Alright, listen up. Rusty here, breaking down the next couple of weeks for you.
We’re looking at one spot, Jongensfontein, a reef that’s consistent and facing south. Water temp is about 61°F, which is normal for this time of year.
The pattern is a slow start. The first window worth a look is Tuesday the 15th. Tuesday afternoon, some clouds, a west wind at 19 mph blowing cross-off, and a small 5ft easterly swell. The energy is weak (910), and it’s described as “marginal.” It’s clean, but nothing special. After that, it goes ugly. Wednesday through to Monday the 21st is a total loss – cross-onshore winds, messy conditions. That’s a solid 6-day gap of poor surf.
We get a clean break on Tuesday the 22nd. Tuesday morning, clear skies, a light NNE wind at 9 mph blowing cross-off. The swell is 6ft easterly with a short period of 8 seconds and weak energy (546). It’s small and a bit gutless, but it’ll be glassy. Good for a fun intermediate session if the tide plays nice. That afternoon the wind ruins it.
The real standout, the one I’d mark on the calendar, is Wednesday the 30th of September. It’s a long way off, so take it as a promising prospect. Wednesday morning at Jongensfontein, clear skies, a light NNE breeze at 9 mph blowing cross-off. The swell is 7ft easterly, period of 10 seconds, and moderate energy (1144). The forecast says “excellent surf conditions for experienced surfers.” That’s the one. That 7ft is getting into expert territory, but with offshore wind and a decent period, it’ll be chunky and clean. Crowds are “sometimes” an issue, so expect a few heads.
Before that, there’s a monster pulse around Thursday the 24th and Saturday the 26th. Swells of 10ft to 13ft, long period (14 to 16 seconds), and massive energy (over 4000). But the file says it’s too big for this break. That’s big-wave-only stuff, and with cross-shore wind, it’s more of a kite-surfing scenario than a regular paddle.
So, the takeaway: clean, small surf on Tuesday the 22nd for a quiet session, but the real gold is that clean 7ft easterly on Wednesday the 30th of September. That’s your best bet. Keep an eye on the wind as it gets closer.
Rusty.

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.
