The Lowdown

Alright folks, Rusty here. Let’s break this down.

The next couple of weeks is a proper story of two halves. The start is slow, but there are some serious gems hiding in the second half. It's all about timing the wind, as usual.

First real chance is this Sunday afternoon at Dunes (The Dunes). It's a reef break, exposed to the southwest, and the forecast is for a clean, offshore breeze. Swell is a solid 6 feet from the southwest with a long 17-second period – that’s proper groundswell energy. This is one for the experienced crew, but the conditions should be firing. The combined energy is strong at 1416, and it’s going to be clean. Water temps are about normal for this time of year.

Monday morning is still worth a paddle. The surf will be around 4-5 feet from the southwest, with a 15-second period and a light cross-offshore wind. It’ll be clean, but a step down from Sunday. Solid, fun options.

Then things go quiet. From Monday afternoon through to Friday morning, we’re looking at a few days with no real recommendations. The swell drops off, energy readings are weak in the 300s and 600s, and onshore winds mess things up. A good week to get the gear sorted.

Friday morning shows a flicker of life with a clean 3-foot swell from the southwest and a very long 17-second period. It’s small but might offer some clean lines. Not the main event, though.

The real surf starts on Monday, August 17th. Monday morning is glassy. Flat out glassy. The swell is pushing 5 feet from the southwest with a 16-second pulse, and the energy is nearly at 1000. It’s going to be clean, organized, and beautiful.

But the standouts are Tuesday the 18th and Wednesday the 19th. Tuesday morning brings a clean 6-foot swell from the southwest, with that 16-second period and light offshore winds. The energy is climbing to 1394. It’s on. Wednesday morning is the peak. It’s glassy again, with a powerful 6-foot southwest swell and the same long 16-second period. The energy is pumping at a very strong 1791. This will be an incredible session for the experts. This is big, powerful surf, and you need to know what you're doing.

Thursday morning keeps the momentum with a strong 6-foot of southwest swell, though the afternoon winds pick up. Get your morning session in.

As we move into the weekend of the 22nd and 23rd, things settle down to a smaller, cleaner 3-4 feet, with those glassy morning windows returning, especially Saturday afternoon and Sunday morning. Not big, but fun and clean.

So, to sum it up: the early part is a bust. But get ready for Monday the 17th, and clear your schedule for Tuesday the 18th and Wednesday the 19th. That’s the best window of the whole forecast – strong, clean southwest groundswell, light winds, and Dunes at its rawest. Don't miss it.

Rusty, out.

Information about the Dunes Surf forecast

The above surf forecast table for Dunes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dunes can be found by selecting the local surf guide option on the grey menu. Our Dunes 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 (Dunes) 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 Dunes 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.
