The Lowdown

G'day, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.

Alright, the big news is that we've got some solid swell coming through, but a lot of it is going to be a bit of a battle with the wind. The standout sessions are definitely the glassy mornings, and there's a couple of real gems in there.

The water's sitting at 61° at Jongensfontein, which is pretty much bang on average for this time of year. Nothing to worry about there.

We kick off this Saturday morning, the 29th of August, with a small 2ft WSW swell wrapping in. The wind is a moderate cross-off, so it's clean, but the energy is pretty weak (327). It's a marginal one, but it's a start.

Sunday the 30th sees the swell push up to 6ft from the SW, but the wind is a bit messy. Sunday morning has a light cross breeze, but it's not ideal.

Now, Monday the 31st of August is where it gets interesting. The morning is glassy, absolutely no wind, with a 5ft SW swell. The energy is moderate (524), and the conditions are clean. This is a lovely morning for an intermediate surfer.

Tuesday the 1st of September is a cracker. The morning brings a 7ft SW groundswell with a 13-second period, and the wind is a light cross-off from the WSW. The combined energy is strong (1439), and the conditions are clean. This is for experienced surfers only, as it's a bit of a lump. The afternoon turns a bit gnarly with the wind picking up.

Wednesday the 2nd of September is a bit of a write-off. The swell is solid at 8ft, but the wind is onshore and messy.

We then hit a bit of a dry spell. From Thursday the 3rd of September through to the morning of Monday the 7th of September, the wind is a real problem. It's howling onshore most of the time, making conditions poor. The swell is bouncing around, but it's just not worth the paddle.

Monday the 7th of September morning has a small 3ft swell with a very light offshore, but it's tiny.

The wind stays tricky for the next few days, but then we get another gem. Saturday the 12th of September morning is looking magic. Glassy conditions again, with a 7ft WSW groundswell and a 14-second period. The energy is strong (1877), and it's clean. This is another one for the experienced crew.

Sunday the 13th of September morning has a 8ft SW swell, but it's a bit of a cross-shore mess. The swell's there, but the wind isn't doing us any favours.

So, the pick of the runs is clear: Monday the 31st of August morning for the smaller, clean conditions, and Saturday the 12th of September morning for the bigger, glassy groundswell. Both are standouts.

Stay safe out there.

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.
