The Lowdown
G’day, I’m Rusty. Let’s look at what’s cooking for Jongensfontein. It’s a reef break, exposed to the south, and the water temp is 61°F, pretty average for this time of year.
First few days are a bust. Tuesday and Wednesday (August 11th and 12th) are ugly with strong cross-onshore winds and messy surf. Combined energy is pushing 1590 and 2216 but it’s all wind slop. Not worth it.
Thursday the 13th is still scrappy. Morning offers a chance with a moderate cross-shore and a 2ft, 18-second south-west groundswell. Energy is 2980 but it’s only marginal.
Friday the 14th morning is your first real option. Light north-east breeze, 2ft of east-south-east swell, period around 9 seconds. It’s cross-shore and a bit bumpy, but it’s rideable with 1341 energy. That’s the best in a few days.
Saturday the 15th goes tiny – 0.9ft and onshore. Not worth it.
Now listen up. Sunday the 16th morning – light south-west cross-off wind, 0.9ft of clean south-west swell at 14 seconds. Energy is low at 409 but the surface will be glassy. Small, clean fun.
Monday the 17th morning is the standout. Absolutely glassy, zero wind, and the swell jumps to 1ft from the west-south-west with a 13-second period. Combined energy is 1048 – solid. Excellent conditions for experienced surfers. The reef should be humming. Crowds can show up sometimes, but a Monday is your best bet. This is the session to chase.
Tuesday the 18th morning brings a big 3ft south-west swell at 14 seconds, but the forecast says it’s too big for this spot. That’s 2874 energy and clean wind, but it’ll be surging through. Only for the brave.
The end of that week and into the 22nd is hit and miss. Friday the 21st morning has a clean 1ft south-west swell with light offshore wind – good, but not a highlight. Monday the 24th morning shows another pulse: 2ft from the south-west at 15 seconds, clean with a light cross-off and 2123 energy. That’s promising but it’s well over a week out, so keep your fingers crossed.
Bottom line: Monday the 17th morning is your best bet. Clean, medium-period, good energy. The 24th is worth a look but it’s a long way off.
Stay stoked.
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.
