The Lowdown

Alright, Rusty here. Let’s get into it for the next couple of weeks.

The immediate picture isn’t pretty. We’ve got a long stretch of messy, blown-out conditions from today, Thursday the 10th, all the way through to Monday the 14th. The wind is mostly cross or onshore, and the sea state is lumpy and choppy. There’s decent energy in the water – a big, long-period groundswell from the SW – with combined swell energy values sitting in the moderate to strong range (1682 on Thursday morning), but the wind is just ruining it. Honestly, for a reef setup like Jongensfontein, this looks more interesting for kite surfing than proper paddle surfing right now. Wait it out.

The first real glimmer of hope comes on Tuesday the 15th. Tuesday morning we’re looking at a moderate offshore wind from the NW, cleaning up a 5-foot swell from the E with a solid 10-second period. The combined swell energy is moderate (729), but the wind is the key here. That offshore flow will groom the reef nicely. This is your window for some clean, workable waves. The water temp is sitting at 62°, which is about average for this time of year, so a spring suit is fine.

Tuesday afternoon sees the swell drop right off to 4 feet, but a new, very long-period 18-second groundswell from the SW ramps the energy up to 1978. It’s clean with a light cross-off breeze, but that period is *long*. At a reef like Jongensfontein, that long period will produce some proper, powerful lines, but keep in mind it might wall up and make sections harder to find. A good option if you’re keen on a solo session.

The mid-week gets blown out again by Wednesday the 16th with a strong cross-shore, and then we’re back into a messy pattern of wind until the weekend of the 20th and 21st.

Here’s the standout. Look at Monday the 21st of September. Monday morning has a powerful 10-foot SW groundswell with a 16-second period hammering the coast. The combined swell energy is a massive 5205 – that’s very strong. The wind is a stiff offshore from the W, which will make it absolutely howling clean. The caveat? At 10 feet and such long period, this is *only* for experienced surfers. It will be a heavy, powerful reef break. This is the one to circle on the calendar. The following morning on Tuesday the 22nd, the wind swings strong and cross, messing it up again.

After that, the end of the outlook fades into smaller, cleaner but less powerful conditions Friday the 25th, with a clean 6-foot SW swell.

So, to sum it up: the next four days are a write-off. Your best bet for a clean session is Tuesday the 15th. The big daddy of the forecast is Monday the 21st, but that one is a serious, expert-only beast.

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.
