The Lowdown

Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like for us.

We’re starting off a bit slow, but it builds into a solid run of waves. The first real action kicks off Friday the 28th of August at Kaaimans River Mouth. It’s a bit of a slow start in the morning with a light cross-on breeze and a 4ft S swell, but the energy is already there (797). The afternoon is where it’s at though – the wind swings around to a light cross-off and the waves clean right up. It’s a beginner-friendly spot, and it’s consistent, so you’ll get waves. The water is sitting at 61°, which is about average for this time of year, nothing unusual there.

Saturday the 29th stays clean with a cross-off wind, but the swell drops a little, coming in around 3ft from the S. Still fun, but not the standout. The afternoon shows a shift to a 2ft SSW swell with a longer 13-second period, which will give the waves a bit more shape.

Now, Sunday the 30th is the first real highlight. The morning sees a jump in size to 6ft from the SW, period at 9 seconds, and it’s clean with a light cross-off breeze. The energy is up (850). But the afternoon is where it gets special – glassy conditions, 6ft of SW swell, and a 12-second period. The energy is strong (899). That’s a beautiful combo. The swell is a bit long in period, so at a river mouth setup like this, you’ll want to watch for it to run a bit straight, but the glassy surface will make it worth the paddle out.

Monday the 31st keeps the run going. Morning is clean, 5ft SW swell with a 12-second period, and a light cross-off breeze. Solid. The afternoon gets a bit messy with a cross-on wind, so aim for the morning session.

Then we get into the big stuff. Tuesday the 1st of September is a standout. The morning is a bit tricky with a cross-shore wind and 7ft of SW swell, but the afternoon is fantastic. The wind goes cross-off, still light, and the swell holds at 7ft from the SW with a 13-second period. The energy is massive (1535). This is getting into the bigger range, so it’s better for experienced surfers, but the quality is excellent.

Wednesday the 2nd, though – that’s a warning. The morning sees a monstrous 13ft SSW swell (7742), but it’s just too big for this break. It’s cross-on and the wind is light, but the size is for experts only, and even then, it’s sketchy. The afternoon gets worse with a 16 mph cross-on and big, choppy 12ft waves. Skip this day.

Thursday the 3rd is a write-off. Strong onshore winds and rain, 7ft of messy swell. Not worth it.

The weekend of the 5th and 6th of September is a mixed bag. Saturday the 5th is still big, 10ft, but the wind goes cross-off in the afternoon, making it look cleaner. Still, it’s big, so it’s for the crew who know what they’re doing. Sunday the 6th afternoon is a surprise gem – 5ft SW swell with a very long 16-second period, and a light cross-off breeze. The energy is high (1946), and the conditions are clean. That long period will make for some proper lines, but it’ll be a bit tricky at the river mouth.

The second week is quieter. Monday the 7th has onshore wind and a 7ft ESE swell, but it’s a bit messy. Tuesday the 8th morning is glassy, but the swell is small, only 4ft from the ESE. After that, the energy drops off significantly through the 9th and 10th, with small, weak swells and poor winds. There’s a bit of a pulse again on the 11th of September with a 7ft SSW swell and a 12-second period, but the wind is onshore, so it’s marginal.

The very last day, Saturday the 12th of September, is a wildcard. The morning has a 5ft SSW swell with a very long 16-second period, but the wind is a light cross-on. The energy is high (2600). But the afternoon is glassy and absolutely massive – 16ft from the SSE. That’s way too big for this break, and it’s only for the most extreme. The energy is off the charts (5031), but it’s a no-go for paddle surfing.

The best on offer is Sunday the 30th of August, afternoon session, with clean, glassy 6ft SW swell. That’s the one to circle. The second best is Tuesday the 1st of September afternoon for the experienced crew, with clean, powerful 7ft SW swell.

Stay safe out there.

Rusty.

A general guide to surfing at Kaaimans River Mouth can be found by selecting the local surf guide option on the grey menu.

Further information to help with frequently asked questions about our surf forecast for Kaaimans River Mouth 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.
