The Lowdown
Alright, let’s break it down. You’re gonna have to be real patient here because the first few days are total garbage. Don’t even look at the ocean until things clean up.
The main spot is Riet River, a point break that loves a good SSW swell. The water’s running a bit colder than usual for August, so don’t forget a wetsuit.
We’ve got a big stretch of junk right at the start. Wednesday the 26th and Thursday the 27th are blown to bits with strong winds and messy, lumpy surf. Total waste of time. Friday morning the 28th is the first real chance – a clean 4ft of S swell with offshore wind. It’s small but glassy, and that’s worth a session.
Saturday the 29th is average with a cross-shore chop in the morning, but the afternoon goes dead flat calm with a tiny 3ft S swell. Not exciting, but rideable on a longboard.
Sunday the 30th and Monday the 31st are a mixed bag. Sunday has an 8ft SW swell but nasty wind, so it’s messy. Monday though? Sunny, glassy, and a clean 5ft SW swell with no wind – that’s a proper highlight. The ocean will look like a mirror, and the waves will have some push.
Tuesday the 1st of September sees a 5ft SW swell with offshore wind in the morning – clean and workable. The afternoon bumps up to 7ft from the SSW, but the wind turns cross-onshore and it gets a bit crumbly.
Now, the gem of the whole two weeks: Wednesday the 2nd of September. We’ve got a solid 10ft SSW groundswell with a 13-second period, combined energy at a strong 2,737, and gentle offshore wind. That’s a serious session for experienced surfers. This point will deliver long, powerful lines. The 13-second period means good shape and energy, but long waits between sets – paddle out smart.
Thursday the 3rd is a complete washout – strong onshore winds and rain. Skip it.
Then we hit a crazy spike on Friday the 4th of September. The swell is predicted to be massive – 28ft from the SSE with a 14-second period and a combined energy of 26,638. That’s way, way too big for this break. It’s a gale-force cross-onshore mess. This is more for kite surfing, not paddle surfing. Saturday the 5th is similar – insane 21ft swell, but clean with cross-offshore winds. Still, only for the most experienced nutters.
Sunday the 6th of September calms down to a still-chunky 12ft SSE swell with offshore wind – that’s manageable for experts, but not for the faint of heart. The energy is still strong at 4,319.
After that, the surf slowly fades through Monday and Tuesday, dropping under 3ft with clean but weak conditions. Wednesday the 9th is tiny – 2ft with light wind, just surfable. Thursday the 10th brings a fresh pulse of 7ft SW swell, but it’s completely trashed by strong onshore winds.
Best bet? Wednesday morning the 2nd of September at Riet River – 10ft SSW, offshore wind, clean, and powerful. Monday the 31st of August is your second pick for a cleaner, smaller session. Everything else is either too small, too windy, or way too big to be fun.

Information about the Riet River Surf forecast
The above surf forecast table for Riet River provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Riet River can be found by selecting the local surf guide option on the grey menu. Our Riet River 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 (Riet River) 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 Riet River 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.
