The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our local reef.
We’ve got a small window of clean waves on the horizon, but it’s a bit of a mixed bag. The real standout is going to be Friday morning, the 14th, with some proper conditions. Then we’re looking at a long wait for the next real chance, which finally shows up over a week later on the 23rd of August.
Thursday morning (13th August) is a write-off. We’ve got a 6ft swell from the SW, but a 12 mph cross-shore wind is making it a lumpy mess. The wave energy is massive (4174), but it’s just not surfable. The wind drops right off by Thursday afternoon, going glassy. That 5ft SW swell with a 17-second period is clean, and the water temp is about average for the time of year. It’s a solid option for experienced surfers, but for the true highlight, you want to wait for the morning.
Friday morning, the 14th, is the pick of the early period. We’ve got a clean 4ft SW groundswell coming in at 16 seconds, and a 12 mph offshore wind from the NNW is grooming it perfectly. The energy is still decent (1042). This is the kind of reef session you dream about – clean, lined up, and just for the crew who know. It’s a consistent break, so the sets will keep coming. Friday afternoon turns ugly with a switch to a 9 mph cross-onshore, dropping the quality to zero.
Then we hit a dry spell. From Saturday the 15th right through to the 22nd of August, it’s all poor surf conditions or marginal calls. The swell stays small or gets messy with onshore winds. There’s a brief moment on Monday the 17th with a 5ft SW swell, but a light cross-onshore keeps it from being anything special. The energy is weak (819). You’re better off waiting.
The next real glimmer of hope comes on Sunday morning, the 23rd of August. A 6ft SW groundswell (12 seconds) rolls in with a glassy, light offshore breeze from the WSW. The energy is strong (1152), and the description says it’s excellent for experienced surfers. This is a long-range call, so it’s promising but not locked in. The water temp is still average. After that, the outlook gets messy again with strong cross-onshore winds and bigger, lumpy swell from the east that’s just not going to work for this reef setup.
So, to sum it up: Friday morning the 14th is your best bet early. Don’t bother for the next week. Then keep your fingers crossed for Sunday the 23rd.
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.
