The Lowdown
Alright, folks, let’s talk about Jongensfontein. We’re starting on Thursday, 27 August, and the first few days are a bit of a mixed bag, so don’t be in a rush.
Thursday morning has a 6ft SSW swell with a 12-second period, giving a solid energy reading (1330). The wind is light and cross from the NE, so it’s a bit messy. Not ideal. But Thursday afternoon is the real gem – the wind goes glassy from the SE, dropping to 4ft S swell. That’s a session for the purists. The reef will be working, but it’s a good intermediate size, nothing too hairy. The water temperature is about average for the season.
Friday and Saturday are poor, with onshore winds and the swell dropping out. Not worth the drive. Sunday brings a 7ft SW swell, but with a strong 15 mph cross-shore, it’s choppy and messy.
Monday, 31 August is a dud. But Tuesday, 1 September is the big one. Tuesday morning offers a clean 7ft SW swell (1443 energy) with a whisper of a WSW wind, only 3 mph. That 12-second period will make the waves stand up beautifully. It’s solid intermediate territory, not for the timid. The afternoon blows up with a 10ft SW swell and a stiff cross-onshore, so get it early.
Wednesday, 2 September has a 10ft SW swell (3525) but the wind is cross, and it’s just too big for this spot. That’s expert-only, if you’re feeling lucky. The rest of the first week and into the second week is a run of massive, oversized swells – 15ft to 24ft – with strong onshore winds or clean cross-offshore, but the sheer size means it’s unmanageable at Jongensfontein. The energy numbers are huge (up to 15673), but it’s not for paddling.
The second week calms down. 8 September sees a 10ft ESE swell (2526 energy) with clean conditions, but again, that’s big. The 9th and 10th drop to smaller, poor-quality waves, and the 11th is a total loss with fresh cross-shore winds.
The two highlights are Thursday afternoon, 27 August, and Tuesday morning, 1 September. The first is a glassy, clean little session, and the second is a proper, long-period groundswell. Get in the water early on Tuesday.

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.
