The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for Jongensfontein.
We start slow, but by Saturday the 18th you get something to ride. That southern groundswell comes in at 4ft from the S with a period of 12 seconds. That’s long-period energy, so the reef will shape it nicely. Combined swell energy is moderate (537), and with a smooth cross-off breeze, it’ll be clean. Water temp is about average for this time of year.
Sunday morning stays clean with a 5ft SW swell, but the real standout is Monday the 20th. That morning is pure glass – no wind, a 6ft SW groundswell (10 seconds), and combined energy moderate (942). It’ll be uncrowded. This is the pick of the first week.
Tuesday morning the 21st brings a nice 6ft SSW swell with a very long 14-second period. Glassy wind. Good groundswell pumping with strong energy (1440). For experienced surfers, this is an excellent session. Wednesday morning the 22nd keeps it clean with a 6ft SW swell and cross-off wind.
Now Wednesday afternoon the swell jumps to 10ft. That’s expert-only territory with combined energy at 2221. It’s going to be pushing limits.
Thursday the 23rd morning, glassy again with a clean 6ft SW swell. Then Friday the 24th: a massive 12ft SSW swell with a very long 16-second period. Combined energy hits 5455 – that’s very strong. That much size on a reef is for the brave only. Wind is glassy, but the swell is too big for the break’s usual shape. Afternoon stays similar.
Saturday the 25th drops to 8ft but the wind goes strong from the east at 18 mph, making conditions poor. Sunday the 26th is still big but messy. Through the 27th it’s blown-out with near gale winds. Skip that.
Tuesday the 28th flips: swell direction changes to E at 8ft. Combined energy is 2421, strong. Wind is clean offshore from the WNW. That’s an excellent window for experienced surfers.
From the 29th on, the energy drops. Swell sizes slip below 5ft, and by the end of the month into August, it’s small and inconsistent. The first of August has a glimpse of a 4ft SSW swell with clean wind, but overall it’s fizzling out.
If you’re picking the standout, it’s Monday morning the 20th – glassy, chest-high groundswell, clean, uncrowded. Tuesday the 21st morning is a close second for experienced crew. The big Friday the 24th is not a surfer’s day unless you’re charging heavy reef.

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.
