The Lowdown

Alright, Rusty here. Let’s have a look at what’s shaping up for our local patch.

We’ve got a bit of a wait on our hands, I won’t lie. The first week is pretty gutless, with a lot of afternoons getting chopped up by the wind or just not having enough push. The real standout action is a long way off, so don’t get too excited just yet.

Let’s start with the only spot on the cards: Dunes. It’s a consistent reef break that’s exposed to the southwest swell, and it likes the swell coming from the SW. The water is sitting at 76°, which is about 2° warmer than average for this time of year – nothing too wild, just a pleasant little bonus.

The first decent window doesn’t open up until Monday the 27th of July. That morning, we’ve got a moderate offshore breeze from the SE, grooming a clean 2ft of SW swell. The period is a very long 15 seconds, which means proper groundswell energy. The combined energy is moderate at 211, so it’s got some grunt. That offshore wind will make it look clean, but that long period at a reef might mean the sets are a bit fat and slow in the lineup. Still, it’s the best we’ve seen for a while.

Tuesday the 28th of July morning is also a good call. A gentle offshore from the ESE, with 3ft of SW swell at 14 seconds. The combined energy is up a touch to 218. It’s clean, and the swell is a bit more user-friendly than the day before.

The real standout, and the one I’m most stoked about, is Saturday the 1st of August. The morning brings a clean cross-off breeze from the SSE, but the swell is a solid 7ft from the WSW, with a 15-second period. The combined energy is massive at 2630 – that’s a serious amount of power. Let’s be real, though: at 7ft, this is getting too big for beginners and is really only for the experienced crew. The reef is going to be handling a lot of water, so expect some heavy, dredging lines. The wind is clean, but the size will make it a mission. If you’re a solid surfer, this is your window.

After that, the swell drops back, but we get a few more mornings of clean, lined-up waves. Sunday the 2nd of August morning has a strong offshore from the SE at 25 mph, with 5ft of SW swell. That wind is strong, so it’ll be clean but the paddle out will be a workout. The combined energy is still strong at 904.

For the rest of the second week, the mornings are generally clean with cross-off winds, but the swell sits around the 4ft to 4ft mark. It’s surfable, but nothing to write home about. The afternoons, as usual, are mostly a write-off with onshore winds.

So, to sum it up: the first week is a write-off. The best surf is on the 27th and 28th of July for smaller, cleaner waves, and the big one is on the 1st of August for the experts. Stay patient.

Rusty.

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.
