The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' at Jongensfontein for the next couple of weeks. This reef break is a consistent performer, and we’ve got a solid run of south and south-west groundswells on the cards. The water is sitting at a normal 62° for this time of year, so nothing weird there.
The first session to get excited about is Saturday morning, the 18th of July. We’re looking at a clean 4 ft swell from the south, with a period of 12 seconds, offering a decent amount of energy (537). The wind is a light 6 mph from the west, so it’s a cross-off breeze. That’s a nice, clean start to the weekend for a paddle out.
Sunday morning, the 19th, keeps the fun going with a 5 ft south-west swell and a 12-second period, packing a punch with 1204 energy. The wind is up to 12 mph from the west, but still cross-off, so the face will be clean. It’s a good size for intermediates.
The real standout, and the one you want to circle, is Tuesday morning, the 21st of July. Glassy conditions, zero wind, and a solid 6 ft swell from the south-southwest with a long 14-second period. The energy is a beefy 1656. This is the pick of the bunch for experienced surfers – clean, powerful lines rolling in. The period is long, so expect some nice, well-shaped waves with gaps between the sets, making it easier to get out the back.
Wednesday morning, the 22nd, is also a ripper. A 8 ft swell from the south-west with a 12-second period, powered by 1845 energy, and a light 6 mph offshore breeze from the north-west. That’s clean, makeable waves for the experienced crew.
Now, through the rest of the week, we see the swell size bumping up. Wednesday afternoon, the 22nd, hits 10 ft from the south-west, and the energy jumps to 4060. The wind is light, but that’s a big, powerful swell for this reef. It’s a bit much for a paddle; you’d be looking at a kiting session if the wind cooperates. Thursday and Friday, the 23rd and 24th, stay big with 10 ft swells, but the wind is a bit tricky, mostly cross or cross-on.
The following weekend, Saturday the 25th, has a choppy 8 ft swell with a strong onshore breeze, so keep the board in the car. Sunday the 26th, though, is a beauty. A 7 ft and 7 ft south-southwest swell with a very long 16-second period (2194 and 2402 energy), and a clean cross-off wind from the north-northeast. That’s an excellent call for experienced surfers on a reef – the long period will groom those lines perfectly.
The first week of August kicks off with a massive 10 ft swell on Saturday the 1st, but the period is a short 8 seconds, so it’s a bit of a mushburger. The wind is clean, but it’s just too big for a comfortable paddle. The best call to end the run is Sunday morning, the 2nd of August: a clean 7 ft from the east-southeast, and then a nice little 4 ft south-west swell in the afternoon with a 14-second period and 1081 energy. That’s a tidy way to finish the run.
Overall, the standout is Tuesday the 21st for the glassy conditions and the Sunday the 26th for the long-period groundswell. Get on it.
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.
