The Lowdown
Alright, mates, Rusty here. Let's chew the fat on what's in the water for the next couple of weeks.
First up, we're looking at a solid run of clean, long-period groundswell at Jongensfontein, a reef setup that's consistent and takes the swell head-on. The water temp is about what you'd expect for this time of year, nothing crazy.
The weekend starts off a bit shaky. Saturday morning brings a small 3-foot SSE swell, but with a cross-off wind it's clean, though the energy is moderate (417). Things pick up Saturday afternoon with a 3-foot SW swell, a longer 14-second period, and cleaner conditions (483). It's not the biggest, but it's a start.
Sunday is a write-off. The swell jumps to 6 feet from the SW but the wind is messy, cross-shore in the morning and cross-on in the afternoon, making it choppy.
Now, Monday morning the 31st of August is a real gem. The wind is glassy, dead calm, and we've got a clean 5-foot SW swell with a nice 11-second period. The energy is moderate (533), but the conditions are perfect. This is a standout for the whole period for pure, clean fun.
Tuesday the 1st of September is the big boy. The morning sees a 7-foot SW swell with a 13-second period, powerful as hell (1525), and cross-off winds. The setup is excellent for experienced surfers, but the afternoon gets a bit dicey with a fresh 19 mph cross-off wind and an 8-foot swell, making it marginal. This is the other standout, but it's for the experienced crew only.
From Wednesday the 2nd of September onwards, things go downhill fast. The wind swings onshore and strengthens, turning the surf into a mess. We get periods of strong cross-onshore winds, choppy conditions, and even some rain. A couple of days in the second week, like the 6th of September, have a clean 10-foot swell, but it's too big for this break, and the kite surfers would have a field day.
The rest of the run up to the 13th of September is a long stretch of poor surf with strong onshore winds and messy, blown-out conditions. A few small windows of clean, cross-off wind pop up, like the 10th of September morning, but the swell is tiny at 2 feet. The long-range energy on the 11th and 12th of September is huge (1509 to 2838), but it's all blown out by strong winds.
So, the clear standouts are Monday the 31st of August morning for the glassy, clean fun, and Tuesday the 1st of September morning for the big, powerful, clean swell for the experts. The rest is a bit of a gamble or a write-off.
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.
