The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the next couple of weeks.
Alright, straight up, we've got a mixed bag coming our way at Jongensfontein over the next 16 days. The water temp is sitting at 61°F, which is pretty much spot on for this time of year, no surprises there.
The forecast starts from Monday the 7th, but honestly, the first few days are a bit of a write-off. Monday morning offers a 6ft SSW swell, but with a cross-shore wind, the combined wave energy's still got some grunt at 2241, but the conditions are just marginal. By the afternoon, it's even worse. Tuesday and Wednesday are the same story – small, onshore winds, and low energy. You're looking at a solid block of nothing much until we get to Thursday morning, the 10th. That's a gap of a couple of days with no real recommendation.
Now, Thursday morning the 10th sees a bit of a pulse. A 7ft SW swell rolls in with a very long 16-second period, and the energy jumps right up to 2169. The wind is light and cross-shore, so it's not blown out, but the forecast still calls it marginal. It's a promising sign though, as the longer period suggests some clean lines if you pick your tide right. That long period, combined with the reef setup, means it should hold up well, but keep in mind that long-period groundswell at a beach setup can sometimes straighten out – here, the reef will be your friend.
Then we hit a bit of a lull again Friday the 11th and Saturday the 12th, with onshore winds and shorter period junk. But hold onto your board, because the standout of the whole outlook is Tuesday the 15th afternoon. The ocean really turns it on. A clean 8ft SW swell, hitting from the optimum S direction, with a very long 16-second period. The wind is a light cross-offshore breeze, making for clean waves. The combined energy is a massive 3379, so there's plenty of power. This is for experienced surfers only – that size and power is no joke, but for those who can handle it, this is the session to circle.
Earlier that same Tuesday morning is also worth a mention. A smaller 4ft SW swell, but with a WNW offshore breeze giving you glassy conditions. The energy is lower at 552, but it’ll be a fun, clean option for intermediates who want to get a few without the heavy juice.
Wednesday the 16th morning looks interesting too, with a big 10ft SW swell, but the wind is a fresh cross-shore, and honestly, the report says it might be too big for this break anyway. The energy is huge at 3178. It's a big, lumpy mess more suited to a bigger, more exposed point. After that, from the 17th right through to the 22nd, it's pretty grim. Strong gale-force onshore winds and rain showers just blow everything out. There are a few cleaner windows with cross-offshore winds on the 20th, but the swell is dropping and the energy is moderate. The very end of the forecast, on Tuesday the 22nd morning, there is a dead-flat 3ft glassy morning, but it's tiny.
So, to wrap it up, keep your eyes locked on Tuesday the 15th afternoon. That 8ft SSW groundswell with clean offshore wind is the best wave you're going to see in this period. The Thursday the 10th morning is a distant second, with a decent pulse but not as clean. The rest is either too small, too windy, or just flat out messy.
Stay keen, and check the charts before you head out. This is Rusty signing off.

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.

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.
