The Lowdown

G'day, it's Rusty.

Alright, we've got a bit of a build-up this fortnight at Riet River. It's a point break, exposed to the south-west swell, and it's an inconsistent spot, so when it does fire, you've got to be on it. The early days are mostly small and average, but the real story here is a late-month monster.

We kick off on Friday the 14th. The morning has a clean-ish 3ft SSW swell with a very long 16-second period, but it's cross-onshore with a gentle breeze, making it a bit choppy. The combined wave energy is moderate (438). The water is feeling the chill at 62°, a massive 5° colder than usual for this time of year – very unusual. Friday afternoon is a write-off with poor conditions. Saturday the 15th morning is where it first gets interesting. We’ve got a cleaner 2ft SW swell, and the wind swings offshore from the west, making for clean surf. The energy is light (208), but it's a good sign. Saturday arvo turns onshore and messy again.

Sunday the 16th arvo is a cracker for the size. The swell lifts to 3ft from the SW (13s period) with a clean, cross-offshore breeze. Wave energy sits at a moderate 275. Monday the 17th sees the swell build. The morning is 4ft with clean cross-off winds and a big jump in energy (960). Monday arvo is even better: 5ft of SW swell, clean, and rated as very good. The points should be running nicely. Tuesday the 18th morning holds at 5ft with light cross-off winds and that clean feel (799 energy). That's a solid run of days.

Now for the standouts. Look at Wednesday the 19th. The morning delivers a solid 7ft SSW swell with that ideal 13-second period. The wind is a light cross-off, leaving it perfectly clean. The wave energy is pumping at 1250 (strong). This is excellent for experienced surfers. If you can get out there, this is a top choice, but remember this spot is inconsistent and can have crowds sometimes, so get in early.

The real standout, the one you've been waiting for, is Saturday the 29th. This is a long way out, but the potential is huge. The morning shows a massive 13ft SSW swell with a 15-second period. Wave energy is colossal at 7851. The wind is a gentle cross-off, keeping it clean. This is exceptional, expert-only territory. It’s a full month away, so treat it as a promising but not yet certain call. The arvo holds that 13ft size but gets a touch of cross-onshore.

In between, the end of the second week has some gnarly, huge stuff. The 22nd and 23rd see 10ft to 13ft swells with strong cross-off winds – that's big, powerful, and clean, but the energy numbers are huge (over 4000 and 6000). These are also for experts only, and the winds are strong enough to make it a bit of a battle.

After that big late-month swell, Tuesday the 25th morning offers a nice reset. A clean 4ft SSW swell, and the wind goes completely glassy (0 km/h). The energy is moderate (586). That'll be a dreamy, clean session for a broad range of surfers.

So, the best on offer are Wednesday the 19th morning for the first solid legit swell, and the big Saturday the 29th for the absolute bomb. The water will be cold throughout, so suit up.

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.
