The Lowdown

Alright folks, Rusty here. We’ve got a mixed bag coming our way for the Riet River stretch over the next couple of weeks. It’s gonna take a bit of patience, but there are a couple of windows where it’ll all come together.

Overall, the pattern starts with a building swell that gets a bit messy, then cleans up for a solid session mid-week. After that, things get blown out and messy for a long stretch, before we see a glimmer of hope further out.

The first real opportunity kicks off on Tuesday morning, September 1st. The swell is coming in at a clean 5 ft from the SW, with a 12-second period. The wind is light and offshore, swinging S at 3 mph, so expect some clean, lined-up sets. The combined energy is pushing into moderate territory (662). The water is sitting at 64°, which is a bit colder than average for this time of year, so you’ll want a decent suit.

The standout window is Wednesday morning, September 2nd. This is the one to circle on the calendar. The swell bumps up to 8 ft from the SSW, with a groundswell period of 14 seconds. Winds are light, cross-offshore from the SW at 9 mph, keeping the faces clean. The energy is pumping hard at 2405, and the quality is described as excellent for experienced surfers. This is a solid, powerful point break wave, but at 8 ft, it’s edging into that territory where you’ll want your wits about you. It’s not for beginners.

Thursday morning, September 3rd, still offers fun waves as the swell drops to 6 ft from the SSW, but the wind shifts and the overall quality is a step down from the peak.

Then we hit a wall. From Friday, September 4th, through to Thursday, September 11th, it’s pretty much a write-off. Strong onshore winds, messy conditions, and a lot of blown-out, lumpy surf. The swell gets huge at times, hitting 13 ft and 12 ft, but with strong cross-onshore winds, it’s going to be a washing machine. Honestly, for a few days there, it’ll be more interesting for the kite surfers than the paddle crew.

After a long, quiet spell, the next flicker of hope appears on Friday morning, September 11th. The swell picks up again to 6 ft from the SSW, with clean cross-offshore winds. It’s a long way out, so temper the expectations, but there’s potential for a good session if the forecast holds.

Alright, that’s the long and short of it. The Wednesday morning, September 2nd session is the one to aim for – a true standout for the experienced crew. The rest of the month is a waiting game.

Catch you in the lineup.

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.
