The Lowdown
Alright, Rusty here. Let's talk about what's coming our way for the next couple of weeks.
Right now, things are looking pretty average, and there's a big stretch ahead where the wind is just going to ruin it for us. We've got a consistent S-exposed reef break on the cards, but the timing has to be perfect. The water temp is about average for this time of year, nothing unusual there.
The first real window I'm looking at is Tuesday morning, the 15th of September. That's our standout. We’ll have a 5ft swell rolling in from the east with an 11-second period – that's a nice groundswell, good energy in the water (828). The wind is a gentle offshore from the NW, so it'll be clean, glassy conditions. The combined energy is moderate, but it's the cleanest we'll see for a while, and on a consistent reef, that's a gem. Expect some crowds here though.
After Tuesday, things fall apart. The wind goes onshore or cross-onshore and stays messy right through until the 23rd of September. That's a solid week of lumpy, choppy, poor surf. The swell sizes hover around 5ft to 8ft, but the wind direction just kills the quality.
Now, keep an eye on Wednesday morning, the 23rd of September. That's a promising one further out. We’re looking at a 6ft SW swell with a 13-second period (1567 moderate energy). The wind will be a light W, cross-offshore, which means clean faces. The report says it’s excellent for experienced surfers, so the shape will be there. It's a long-range call, so less certain, but that's the one to pencil in on the calendar.
Later that week, the 24th of September, we get some bigger SW groundswell energy, with 17-second periods pushing through (2539), but the wind turns cross-onshore again, so it'll be difficult to find a clean one.
All in all, your best bet is Tuesday morning. The rest of the run has a lot of wind-affected days and a few potential standouts that are a week away and need the weather gods to play ball.
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.
