The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks for the Riet River (Riet-River) stretch. We've got a classic story unfolding: a solid, clean pulse to kick things off, followed by a long, frustrating lull, and then a potential heavy hitter way out at the end of the forecast. Let's break it down.
The standout window is Wednesday morning, September 2nd. The water's a bit colder than normal at 63°F, so grab the thicker rubber. But don't let that put you off because the conditions are the best we'll see for a long time. We’ve got a chunky 8ft groundswell from the SSW running at a tasty 13 seconds. The wave energy is pumping hard (2369), and with glassy winds out of the south at just 3 mph, it’s going to be clean, lined-up, and proper. This is an exposed point break, so it’ll handle that size well, but that's pushing into expert territory—it’s gonna be powerful.
After that morning magic, the wind swings brutally onshore from the East by the afternoon and stays ugly for over a week. That Wednesday glass is a one-hit wonder. The surf drops off quickly—Thursday morning on September 3rd is a messy, lumpy 6ft with cross-on winds, and it just gets worse from there.
We go straight into a major drought from Wednesday afternoon right the way through to the morning of Monday, September 8th. That’s nearly a full week of junk. A bit of size shows up on Friday, September 4th, with a windy 12ft, but that’s a short-period, wind-blown mess from the SSE—kite-surfing conditions, not paddle surfing.
Things finally start to look tidy again on the morning of Monday, September 8th. We get a clean, cross-off breeze from the SW and a clean 4ft SSW swell. It’s small, but at least it’s surfable. The swell fades fast after that, and we drift back into tiny, onshore conditions for the rest of the first week and into the second week.
Now, for the long-range call. Keep an eye on Thursday, September 17th. This is the one to get excited about. The forecast is showing a big 10ft SSW groundswell with a very long 15-second period and some serious energy behind it (3728). With a cross-off wind from the SW, that point break should be absolutely pumping with clean, powerful lines. It’s still a ways out, so we’ll have to wait and see if the wind plays ball, but on paper, that is the best setup of the whole 16-day run.
So to wrap it up: get out there Wednesday morning for the real deal, then sit tight through a lot of flat and windy rubbish, until we hopefully get a belter of a swell on September 17th.
Rusty.

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.
