The Lowdown

Alright, let’s break this down. Riet River is a point break that’s exposed to the swell with an optimum direction from the SSW. It’s described as inconsistent, but when it lines up, it can be a classic. The water temperature is sitting at 64°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit.

The first few days don’t offer much. Saturday the 29th and Sunday the 30th are pretty ordinary with cross-off winds and small, messy swell. The combined energy is weak, only 295 and 121 on Saturday, and then 418 on Sunday morning, but the period is short at 8 seconds, so not much punch. This is a wait-and-see period.

Now, Monday morning the 31st is where it starts to look interesting. There’s a glassy 5ft SSW swell with a period of 11 seconds, and the combined energy is moderate at 516. The wind is light easterly, making for clean conditions. This is a solid window for a surf. The stand-out, though, is Tuesday morning the 1st of September. The break is seeing 5ft of SSW swell, period 12 seconds, and a light cross-off breeze from the SW. The combined energy is 549, and the forecast is pointing to very good surf. This is the best of the early week.

Wednesday the 2nd gets a bit bigger, with a 10ft SSW groundswell pushing through on the morning, but it’s cross-on, so it’s messy. The energy is strong at 2598, but this is one for experienced surfers only. Thursday the 3rd morning is a highlight: 5ft SW swell, 12-second period, light cross-off from the NW, and clean conditions. The combined energy is 1072, and it’s being called excellent for experienced surfers. That’s a top pick.

The weekend of the 5th and 6th is a write-off with strong onshore easterly winds and messy, lumpy conditions. The energy is high, but it’s not paddle-friendly. This setup looks more interesting for kite surfing than a traditional surf.

Monday the 7th sees a drop in size with a fresh offshore wind, making for clean but small waves around 4ft. The energy is moderate at 715. This is a marginal session.

The second week gets smaller. Tuesday the 8th morning has a very long-period 16-second SSW swell, but it’s only 2ft, so it’s too small to do much with. The energy is weak at 293. The rest of the week is pretty flat with cross-on winds, until Saturday the 12th afternoon. That afternoon shows a 10ft SW swell with glassy conditions, but the period is 10 seconds, so it’s a bit short. The energy is strong at 1944, and it’s being called excellent for experienced surfers. This is a real standout for the second week, but keep in mind it’s a long-range call.

Sunday the 13th morning has 10ft SW swell, 11-second period, but a fresh cross-off wind, so it’s going to be big and clean but only for the experienced.

So, for the best on offer, I’d say Tuesday morning the 1st of September and Thursday morning the 3rd of September are your top picks. For the second week, Saturday the 12th afternoon is the one to watch.

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.
