The Lowdown

Rusty here again, this time in feet and miles per hour.

Let's break down what’s coming for the next couple weeks at Jongensfontein. There’s a bit of a rough patch in the middle, but a couple of sweet days pop up towards the end.

We start off okay on Tuesday the 15th. The morning session is clean off a light offshore from the NNW, with chest-high swell at 5ft from the east. Combined energy is moderate at 691. The water’s sitting at 62°, which is what you’d expect for this time of year – no surprises there. This is a good start.

By Tuesday afternoon, things get a bit sketchier. The wind goes cross-off from the west at 13 mph, but the wave comment hints at tide issues. Swell is a touch smaller at 5ft.

From Wednesday the 16th right through to the 24th, it’s pretty grim. Onshore winds and cross-onshore mess up pretty much everything. Swell sizes vary, but blown-out junk is blown-out junk. Friday the 18th sees strong winds at 28 mph and wave energy climbing into the 1587 range, but it’s not for surfing. Saturday the 19th pumps a 10ft ESE swell with a short 9-second period, but with easterly winds howling at 25 mph, it’ll be a mess for a surfer – a good day for the kite crew though.

After a long, frustrating wait, Thursday the 24th afternoon finally delivers. Glassy conditions, a 6ft swell from the SSW with a nice long 13-second period. Wave energy is a sturdy 1373. The wave comment calls it excellent for experienced surfers. That’s the one.

Friday the 25th morning follows up strong with offshore wind from the west at 13 mph, and a clean 8ft SW groundswell with that same long 13-second period. Energy hits a massive 3342 – that’s strong, powerful stuff. This is an experienced surfer’s window; beginners should sit this one out.

Saturday the 26th stays rideable with a consistent 6ft SW groundswell, but the wind goes cross-shore, so it’s less lined up than the days before.

One more small window shows up on the 30th of September. Glassy morning, 7ft from the ESE with a short 8-second period. Waves will be clean but lack the punch of a longer period swell.

So, put a pin in Thursday the 24th afternoon and Friday the 25th morning. That’s your best chance for proper, clean, rideable surf after a long average run.

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.
