The Lowdown
Alright, let’s talk waves at Jongensfontein in feet and knots for those who think that way.
The next few days are a total bust. A strong onshore wind out of the southeast is just thrashin’ the ocean. Thursday kicks off with a combined swell energy of 681, but that 12 mph onshore breeze and light rain are ruinin’ any chance of a clean wave – it’s a choppy mess. That wind stays nasty through Friday and Saturday, gustin’ over 20 mph, and the swell direction is all over the shop. The water’s sittin’ at 61°F, which is right where it should be for this time of year. Save your energy, you’re not missin’ anything.
But hold up. Monday, the 7th of September, is where it gets good. The wind goes glassy in the morning – a whisper at 3 mph from the ENE. We’ve got a 5-foot groundswell from the SSW with a long 14-second period, and the combined swell energy is 1824 – that’s strong, solid power. On this reef, that long-period swell will wrap in with proper shape and lines. This is the standout: clean, powerful, and glassy. For experienced surfers only, but it’s a world-class morning.
The middle of the week fades into smaller surf with light winds, nothin’ to write home about. Then on Sunday the 13th, the swell jumps back to 11 feet, but that 25 mph cross-onshore wind from the east-southeast will shred it into a lumpy mess. Too much wind, too big for the setup.
Now, look ahead to Wednesday the 16th of September. The morning brings a 5-foot SSW groundswell with a very long 17-second period – that’s rare, that’s proper energy. The combined swell energy is 2096. The wind is light at 9 mph from the west-southwest, which is cross-offshore – it’ll groom the face beautifully. That’s your second standout session for the reef. Just watch out – the afternoon turns into a near gale from the southwest, so get your waves early. And Friday the 18th afternoon sees a 10-foot pulse from the south-southwest with a combined energy of 4494, but the wind is onshore, though light. It’ll be raw and heavy – only for the serious crew.
So, two absolute gems on Monday the 7th and Wednesday the 16th, and a whole lot of choppy, windy days in between. Pick your windows, and when the wind goes offshore on that reef, you’ll be smilin’.

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.
