The Lowdown
Alright, gents, Rusty here. Let’s size up the surf at Jongensfontein for the next couple of weeks.
Water temp is a normal 61°F, nothing out of the ordinary. The issue is we’re starting with a stiff cross-onshore wind at 25 mph and a messy, powerful SSW swell. The combined energy is a massive 5044 (very strong), but the wind is ruining it. No waves worth talking about for the first few days.
We get a window of something on Tuesday morning, September 8th. The wind goes dead calm, glassy, and the swell drops to 5ft from the east with a short period of 9 seconds. The energy is a modest 671. It’s clean and small. The morning is your only chance, as the wind turns onshore in the afternoon.
The real standout is Thursday morning, September 10th. The swell builds to 8ft from the southwest with a very long period of 16 seconds – that’s proper groundswell. The combined energy jumps to 2494 (strong). The wind is light and changing, barely a puff, so the surface will be clean. This is a reef break, so that long-period swell will line up well. The 8ft is getting big for rookies, but it’s manageable. Crowds are possible, but it’s worth it.
Then we hit a lull. Friday and Saturday are a washout with onshore wind and rain.
Next good one is Monday morning, September 14th. The swell is 6ft from the southwest with a 9-second period, and the wind is a light cross-offshore breeze. The energy is 1059 (moderate). The forecast says excellent conditions for experienced surfers, and the wind will keep the faces clean.
The following Tuesday morning, September 15th, is also worth a look. The swell is 5ft from the southwest with an 11-second period. The wind is light cross-off, and the energy is 934 (moderate). Clean and well-shaped.
After that, it’s junk again. A big storm brings heavy rain and gale-force winds from the 16th through the 18th, blowing it out. The swell hits 8ft, but it’s unsurfable.
The last day, Saturday, September 19th, is a weird one. The afternoon shows a 10ft swell from the southeast with a clean cross-off wind. The forecast says the 10ft is too big for this break – that’s expert-only stuff. The energy is 1640 (strong). If you’re a big-wave charger, it might be a beast, but for most of us, it’s a spectator day.
The pick of the fortnight is Thursday morning, September 10th, for that long-period groundswell and clean conditions. The Tuesday morning, the 8th is your backup for a smaller, clean session.
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.
