The Lowdown
Alright, this is Rusty. Let's get stuck into what's happening at our local spot.
The next sixteen days are a bit of a mixed bag. We're looking at a solid start, then a big spell of rough conditions, before things possibly clean up again towards the end. The water temp is about average for this time of year, nothing unusual there.
The main event looks to be Jongensfontein on that Tuesday morning, the 1st of September. We've got a clean 7ft swell rolling in from the SW with a 13-second period. The wind is light and offshore from the W, so it should be glassy and well-shaped. The energy is strong (1526), so this is the one for the experienced surfers out there. A solid, punchy groundswell.
The Saturday before that, the 30th of August, is a bit of a write-off with a messy 6ft cross-onshore swell. The Monday morning (31st) is cleaner but smaller, with a 5ft SW swell and a fresh W cross-offshore breeze. It's a bit average, but better than the afternoon when the wind swings onshore.
Now, after that Tuesday, things get wild. From Wednesday, the 2nd of September, the swell just keeps pumping, but it gets too big for this break. We're talking 15ft to 30ft swells with some serious gale-force winds. It's a beach-and-reef setup, so this is more kite-surfing territory than paddling. That big, messy period lasts through the 4th and 5th.
Look, the 6th of September (Sunday morning) is a possible standout. The swell has dropped to a still-chunky 7ft from the ESE, and crucially, the wind is a gentle offshore from the NW. That's clean. The energy is still strong (1840), but it's a big swell for a break this size, so only for the hardcore crew.
The week after that tapers off. The 7th of September is small and weak, and from the 8th to the 10th, it's either too small or too messy with onshore winds. The 10th of September morning sees another big 10ft ESE swell, but it's a short-period, wind-swell affair (7 seconds) so it'll be a bit of a washing machine. The 11th and 12th are just too big and raw again.
So, to boil it down: your best bet is the Tuesday morning, 1st of September, for a proper, clean groundswell. The Sunday morning, 6th of September, is your next best hope, but it's a big, powerful wave. The rest of the window is a lot of swell and wind, or flat and moody.
Rusty.

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.
