The Lowdown
Alright, let’s talk about what’s coming up. The next couple of weeks have some potential, but you’ll need to pick your moments.
Right now, it’s a slow start. The first real option is Monday the 14th, but it’s not great. Light rain, a cross-on breeze, and a messy 7ft swell from the ESE. The water’s at 61°, normal for this time of year. The wave energy is moderate (1082). You could paddle, but you’ll be fighting the chop.
Tuesday the 15th is the one to aim for. Morning at Jongensfontein (reef) is looking clean. A light offshore wind from the west, with 5ft of east swell. The combined energy drops to 691, but the wind is clean and the shape should be good. The afternoon holds up too, with a 5ft east swell and an 11-second period, giving it a bit more power (916 energy). This is your best bet – get out there Tuesday if you can.
Wednesday the 16th goes bad fast. The wind swings onshore and picks up, and the swell drops. By the afternoon, it’s onshore and messy. The rest of the week, from Thursday the 17th through the weekend, is blown out. Strong winds, choppy conditions, and the swell gets bigger but uglier. Saturday the 19th sees a big 10-13ft ESE swell (energy up to 3215), but with a strong cross-on wind, it’s a mess – more for kites than surfers.
There’s a gap after that. Monday the 21st and Tuesday the 22nd are still marginal, with onshore winds and lumpy conditions. Nothing worth getting excited about. The next real chance is Friday the 25th. The wind turns cross-off from the WSW, and we get a clean 7ft swell from the ESE. The energy is moderate (1097). It’s a bit windy, but the clean conditions could make it work. Could be a good session for the experienced crew.
After that, it fades again. The last few days of September are small, onshore, and messy. A long-period SW swell shows up around the 26th, but the wind kills it. Tuesday the 29th has a chance for a glassy morning, but the swell is tiny and the direction is wrong.
Overall, the standout is Tuesday the 15th at Jongensfontein. Get it while it’s clean.

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.
