The Lowdown
Alright, Rusty here for the imperial version.
We’ve got a slow start, but things pick up. Tuesday the 18th is a washout with cross-shore wind and marginal surf. The first real action is Wednesday morning, the 19th.
The absolute standout is Thursday morning, the 20th of August. The swell is 10ft from the SW with a 13-second period, and the wind is glassy. That’s a dream setup at Jongensfontein. The combined energy is massive at 3423, so there’s serious power. This is too big for beginners, and even intermediates need to be careful. It’s a reef break, so the long period groundswell will line up perfectly. Crowds are possible, so don’t sleep in.
Wednesday morning, the 19th, is a solid warm-up. You’ve got 7ft SW swell with a 12-second period and a light offshore WSW wind. Clean conditions with energy at 1445. Good for experienced surfers.
Saturday the 22nd is a case of too much. Swell pushes to 10ft to 13ft, and while the wind is clean cross-off, the energy is insane at 5518 on the afternoon. This is expert-only, and honestly, with that power and a strong breeze, it might be more for the kite surfers.
Sunday the 23rd morning is a nice reset with 8ft SW swell, light cross-off wind, and a clean lineup. Good for experienced folks.
Then we hit a rough patch from the 25th to the 30th. The wind is mostly onshore or cross-onshore, and conditions are poor. There’s a small window on Wednesday morning, the 26th, with a light offshore wind and 5ft SW swell, but the energy is low at 900. It’s a smaller-board session.
The period from the 25th to the 30th is mostly a gap of poor surf. By the 31st, we’re back to marginal conditions with a 7ft SW swell and light cross-shore wind, but nothing special.
The water temp is 60°F, about normal for the time of year, so no surprises.
Focus on the early sessions on the 19th, 20th, and 23rd. The 20th is the one to circle.
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.
