The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cookin’ down at Riet River for the next couple of weeks. It’s a bit of a waiting game, I won’t lie.

The first few days are just plain ugly. Wednesday and Thursday have strong, lumpy cross-onshore winds, and the surf is a mess. The energy is moderate (971), but it means nothing when it’s blown out. You’re not gonna find me out there. That bad stretch runs from the 12th through the 14th, so maybe catch up on sleep.

Now, here’s where it gets interesting. A couple of mornings break the pattern. Saturday the 15th is small, only about 2ft, but that light southwest cross-off breeze makes it clean and glassy. Same deal with Monday the 17th—3ft or so, light wind, clean. These are your small-wave windows for the longboard and a few friends. Nothing to write home about, but they’ll scratch the itch.

But the standout of the whole period is Wednesday the 19th. The wind goes offshore that morning, a moderate breeze, and the swell comes up to a solid 6ft from the southwest. The energy is moderate (551), but the quality is what matters. That’s your main event right there. Dawn patrol, no question. It’s within the reliable forecast range, so I’d be getting amped.

Moving into the second week, it’s all a bit more speculative. There’s some size Friday the 21st—nearly 8ft—but the onshore wind is gonna make that more of a kitesurfing day. Then Saturday the 22nd has a serious pulse of energy (2037) with 6-7ft from the southwest and lighter winds. It could be good, but it’s far out, so treat it as a promising lead, not a certainty.

Don’t forget, Riet River is a point break, but it doesn’t break all the time. You gotta be there when it decides to work.

And one more thing: the water is mighty cold for this time of year, about 63°. That’s a couple of degrees below the norm, so you’ll be wanting the 4/3 at least.

Bottom line: dodge the junk early, grab a clean small wave on the 15th or 17th, and then go large on the 19th. The rest of the stuff is just talk for now. Keep it salty.

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.
