The Lowdown

Imperial Version

Alright, let’s talk Jongensfontein. This reef break is exposed to the south, and the coming days are a bit of a mixed bag, but there are a couple of absolute standouts if you pick your window. Right now, the water temp is running about average for this time of year, nothing weird.

The first few days are quiet. Wednesday the 9th is a write-off with small, weak 3ft swell from the southwest and a cross-breeze. The combined swell energy is a paltry 347 – just not enough grunt. Thursday the 10th sees a pulse of proper groundswell push in, hitting 6ft on the morning with a long 16-second period from the SW, and the energy jumps to 1558 (moderate energy). The wind is light enough to keep it clean, but it’s still a bit marginal. Friday morning the 11th is where it gets interesting: glassy conditions, a clean 4ft SW swell at 12 seconds, and energy at 599. That’s a fun, cruisy session for intermediates, with a small chance of crowds.

The real standout, though, is Tuesday the 15th. The morning starts with a 5ft easterly swell, a light offshore from the northwest, and a combined energy of 1369 – it’s clean and lined up. But the afternoon is the absolute gem: glassy as a mirror, a 5ft SW groundswell with a very long 20-second period, and energy jumping to 2322. This is a proper groundswell with heaps of energy, which is perfect for this reef. It’ll be a bit bigger on the sets and clean as a whistle – best session of the whole window. Expect it to be a little more crowded than usual given the quality.

There’s another promising window on Saturday the 19th morning – 6ft SW swell at 14 seconds, light cross-offshore wind, clean conditions, and energy at 1375. Then Sunday the 20th morning sees a bigger 8ft SW swell with a fresh cross-offshore, but the energy jumps to 4201. That’s getting solid and will pack a punch – only for experienced surfers.

Heads up: Monday the 21st morning has a massive 13ft SSW swell predicted (energy a whopping 7634), but the file says it’s probably too big for the break. That’s a “stay on the beach and watch” kind of day for most.

So to sum it up: if you only paddle out once, make it the afternoon of Tuesday the 15th. If you miss that, the morning of Saturday the 19th is your solid backup. The rest of the window has a lot of windy, choppy periods, especially the second week, but those two sessions are worth setting the alarm for.

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.
