The Lowdown
Alright, let’s talk surf for Jongensfontein in feet and knots. It’s a reef break, open to the south, and it handles that SW groundswell we’ve got lined up. Water temp’s around 60°F, right about average for the season.
First real chance to get wet is Sunday morning, August 23rd. You’re looking at about 6ft of smooth SW swell, 12-second period, with moderate energy (914). Wind? Dead calm. Glass. That’s your best in the first week – clean, no chop, just sets coming through. Magic.
Monday the 24th is smaller but similar: 4-5ft, still SW, a light offshore from the WSW at 3 knots. Still real clean.
Tuesday the 25th pushes up to 7ft with a 13-second period and strong energy (1988), but the wind turns onshore from the ESE at 6 knots. It’s a bit junky by afternoon.
Wednesday the 26th is a wash – easterly wind cranking at 31 knots in the morning, blows the whole day out. Don’t bother.
Now Thursday morning the 27th – this is the second standout. Swell sits around 5-6ft, period 12 seconds, and wind is absolutely calm – glassy water, big energy (1327). Strong, clean waves for experienced surfers. This is a session to remember.
Friday the 28th fouls up again with strengthening east wind. Saturday the 29th starts with a tiny 3ft swell and 30 knot offshore wind – not worth it. Afternoon jumps to 8ft, but period drops to 8 seconds. Messy.
Sunday the 30th gets huge – 13ft from the SW, 13 seconds, but with 31 knot cross-offshore wind. Clean but too big for the break. That pattern continues: Monday the 31st drops to 7ft, lighter offshore wind, good for experienced folks.
From September 1st onward it’s a mix: some clean days at 6-8ft, but Thursday the 3rd jumps to 10-13ft with big energy (2570). Friday the 4th hits 16ft! And it stays huge through the weekend – 13ft to 16ft, massive groundswell with periods up to 16 seconds. That’s way oversize for this spot. The energy numbers go into the thousands, even tens of thousands. Expert only, if anyone dares.
To keep it short: your two best sessions are Sunday morning the 23rd and Thursday morning the 27th – glassy, clean, solid surf without the crazy size. After that, it’s either blown out or swell too big.
Keep your eyes on the horizon.

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.

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.
