The Lowdown
Alright folks, Rusty here. Let’s look at what’s cooking for Jongensfontein over the next couple of weeks.
Right off the bat, we’re in a bit of a flat spell. The first real surf on offer is a small, clean window on Thursday morning, the 10th. It’s not massive, but it’s our first real chance to get wet.
The standout of the whole run is undeniably Thursday morning, the 10th of September. Jongensfontein’s getting a solid 6ft of SSW groundswell, with a very long 16-second period. That’s proper energy moving through (combined swell energy of 1682). The wind is a light WSW cross-offshore, which will keep the reef face clean and lined up. Water temp is sitting at 61°, right on the money for this time of year, so no surprises there. This is a true window for the experienced surfer – the size and power are too much for beginners, but for those who know their way around, it’s going to be excellent.
We have a bit of a chop-out after that. The wind turns onshore and the conditions get lumpy for a few days. Friday through Wednesday of the next week are mostly a write-off, with strong onshore winds and messy surf. Keep your board in the car, but don’t expect much.
Then we get a second, smaller highlight. Monday morning, the 14th of September. It’s glassy. The wind is WSW at just 3 mph, dead calm. The swell drops to 8ft from the ESE, but with a shorter period of 10 seconds. It’s still a clean, powerful wave for those who are comfortable in the 6ft+ range. The morning is the pick, with that glassy surface. The combined swell energy is 1376, so it’s got some punch.
Later in the month, Tuesday morning, the 22nd of September, looks promising too. Clean 7ft swell from the east with a short 7-second period, light offshore wind from the west. The energy is moderate (929), but the clean conditions will make it rideable. A bit of a long-range call, but it’s worth circling on the calendar.
Bottom line: the first week is a dud after Thursday morning. The 14th and the 22nd are the other windows to watch. It’s not a classic run of pumping swell, but there are a few good sessions in there if you’re patient.

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.
