The Lowdown
Alright, let’s get into it.
The next stretch is a bit of a mixed bag, to be honest. We’ve got a solid south swell pushing through, but the wind is going to be a real pain the arse for the first few days. It’s gonna be big and messy before things start to clean up.
That opening run from Sunday the 9th through Tuesday the 11th is a washout. We’re looking at strong southerly winds and surf in the 5.2ft to 9.8ft range, and it's going to be proper choppy and lumpy. The energy is high – around 2450 to 2760 – but it’s raw, junky power. Not worth paddling out for anything but a fight. There’s a bit of a window Monday afternoon with a dropping wind, but it’s still onshore and not really offering anything clean. If you’re a kiter, you might be having a better time than us surfers out there, especially with that cross-off wind coming through on Monday morning. This is not the time for a beginner to be in the water either, with those 8.2ft+ sets.
Wednesday the 12th looks like the start of a transition. The swell drops back to around 3.9ft, and the wind goes more cross-shore. The period is nice and long, but the energy drops off a cliff to 2700. It’s getting better, but it’s still small and a bit junky. Thursday the 13th is where things start to look up. The morning has a clean cross-off breeze from the NNE and the swell is back up to 6.2ft with a long 19-second period. Energy is climbing to 4135 as well. This is a possible window for Jongensfontein, a consistent reef setup. That long period favors reefs like this, so it could be holding some nice lines before the afternoon becomes more cross-shore.
Friday the 14th is a drop-off. Back to smaller 3.3ft waves with a little less energy. It’s clean in the morning with a cross-off wind, but it’s pretty weak. We’ll wait it out. Saturday the 15th, the swell swings around to the east-southeast, short-period slop. Not what we want. It’s small and confused, basically a no-go.
Now, here’s the standout. On Sunday the 16th, the morning is looking glassy, dead calm with a west wind. The swell has dropped to 3.0ft, but it’s clean and the period is a solid 13 seconds. It’s small, sure, but it could be a funky, clean little session. The energy is only around 432, so you won’t be getting barrelled, but you’ll be getting some clean rides.
Then, Monday the 17th brings back some size. We see 5.6ft waves from the southwest with a 16-second period, and the morning is glassy with a light east wind. It’s got some energy at 1672, and the reef should handle that long-period swell well. This is promising.
But for my money, the real pick of the window is Tuesday the 18th. The morning is dead calm, glass offshore, with 4.3ft of clean southwest swell. That’s going to be the best conditions of the whole run. The wave comment says “very good surf conditions” and I believe it. Light winds, clean lines on the reef. That’s the one to circle on the calendar. It’s not huge, but it’s just about perfect.
After that, things get more uncertain. Wednesday the 19th brings a punchy 6.9ft short-period swell with a cross-off wind, but the period is only 7 seconds, which is junk. The strong winds return Thursday and Friday, and it gets messy again. There’s more size on Saturday the 22nd, 7.5ft from the southwest with a 15-16 second period, but that strong WSW wind, even if it’s cross-off, will put some real texture on the face. It’s promising as a long-range idea, but I wouldn't get too hyped yet for that one. All that southwest groundswell energy (around 2421-2471) will be there, but that ocean breeze is gonna be howling. It’s got potential, though.
The last couple of days, Sunday the 23rd and Monday the 24th, look like 5.6ft of SW swell with light winds. Decent, but it’s not a standout. Overall, the water’s been about average for this time of year. No major warm or cold anomaly coming through. It’s just what we expect.
So, the call is: You wait for that window from the 16th to the 18th, with Tuesday the 18th being the one to get. It will be clean, the reef will hold, and you’ll have a smile on your face.
Keep it salty.

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.
