The Lowdown
G’day, I’m Rusty, and I’m looking at the next few weeks at Riet River. It’s a point break that doesn’t fire all that often, and this forecast is a mixed bag with plenty of wind messing things up, but there are a couple of windows where it all comes together. The water temp is sitting around 64°, which is a bit colder than usual for this time of year, so you’ll want a decent wetsuit.
The first week starts with a bit of a tease. Sunday the 6th has a solid 8ft SSW swell with a very long 19-second period pumping in and combined energy hitting 4996 (strong), but with a 16 mph easterly onshore wind, it’s poor. Monday the 7th is worse – strong cross-onshore winds up to 31 mph making a mess of that 7 to 8ft south swell. Not worth paddling out.
Tuesday the 8th is where it gets interesting. Morning brings glassy conditions with zero wind, and the swell drops to 4ft from the south, 12-second period, with combined energy at 485 (moderate). It’s clean and should offer some fun little lines. That morning session is the best of the early days. The afternoon gets a cross-onshore breeze and drops off. Wednesday the 9th morning is glassy again but the swell is tiny at 2ft – barely surfable.
The standout of the whole period shapes up for Monday the 14th. The morning has a clean cross-offshore breeze, 5ft from the ESE with 11-second period and combined energy of 869 (moderate). Conditions look very good. But the real highlight is Monday afternoon – a jump to 10ft SW swell, 10-second period, combined energy of 3553 (strong). It’s a clean cross-offshore breeze, but at that size it’s pushing into expert-only territory. The point should handle it well given the swell direction matches the optimum SSW. That afternoon is the pick of the bunch, but it’s over a week away, so keep an eye on it.
Other than that, the rest is mostly blown out or messy. Tuesday the 15th has a 6 to 7ft SW swell but with a strong cross-onshore wind. Wednesday the 16th afternoon has an 8ft SSE swell with a short 8-second period and clean cross-off wind – could be punchy but the short period makes it less appealing at a point. The last few days of the outlook stay onshore or cross-on with moderate to fresh winds and small to moderate swell.
Given how inconsistent Riet River can be, this run actually has a few usable windows, especially if you’re ready to jump on Tuesday morning the 8th or that Monday the 14th afternoon. The rest? Not much to write home about.

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.
