The Lowdown
G'day, Rusty here. Look, the next couple of weeks at Jongensfontein are a real mixed bag, and you'll have to be patient. There's a big stretch of messy, blown-out conditions before we get a couple of promising windows.
The only real standout in the whole run is on Tuesday the 15th. Tuesday morning is your best bet. We've got a 5ft swell rolling in from the east, but the wind is offshore from the WNW. The guidance says it's a consistent reef break, and with that clean wind, the sets should be holding up nicely. The water temp is about average for this time of year. It's a good call for an intermediate surfer.
Monday the 14th is a write-off with light rain and a cross-onshore wind messing up the 8ft ESE swell. The energy is moderate (1339), but the wind kills it.
Tuesday afternoon sees the wind go cross-shore and the swell drop to 5ft, but the quality fades. Wednesday through the following Sunday is a long, ugly run. We've got strong onshore winds and a mix of SW swells from 4ft up to 8ft. The energy is moderate to strong (up to 1611), but the wind is just too strong and onshore. This stretch is a write-off. It looks more interesting for kite surfing than paddle surfing.
Sunday the 20th offers a small window of hope. Morning has a cross-shore light breeze with a 5ft SW swell, but the conditions are still listed as marginal. The energy is strong (1423), but the clean-up won't be perfect. Monday the 21st morning has a tiny 4ft SW swell with light onshore wind and marginal conditions.
Then, things get big. From Thursday the 24th, we get huge swell – 12ft to 13ft. The wind is all over the shop, but Friday the 25th is interesting. The wind is offshore or cross-shore with a massive 12ft to 13ft SW swell. The energy is very strong (3196), but the forecast explicitly says it's too big for this break. That's expert-only territory if you’re brave enough. Saturday the 26th morning has a 8ft SW swell with a 15-second period and clean cross-offshore wind. That’s a long-period groundswell that will be best on the reef. The energy is very strong (3378), so it will be powerful.
After that, the wind turns onshore again through the end of the month, with more huge 10ft to 12ft SSW swells and strong energy readings. Not much good for paddling, unfortunately.
Stay patient and keep an eye on Tuesday the 15th morning. That's the one to circle.

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.
