The Lowdown
Alright, folks, Rusty here. Let’s break down this next stretch of swell for our little slice of the coast. We've got one spot that's been on my mind: Dunes.
Right off the bat, Sunday the 6th is lookin' mighty hefty. We got a 2.1m to 2.3m southwest groundswell showing up, and the wind and tide are set up good. The problem? It's just too much power for this spot. There's strong energy in the water, readings of 1805 in the morning, but it's gonna be a messy, closed-out beast. That's a day for the camera, not the board.
Then we hit a flat spell. From Monday the 7th through Friday the 11th, the swell just dies. We're lookin' at waves in that 1.0m to 1.5m range, and even though the mornings are clean with offshore breezes, there's just no poke. The energy numbers are down there in the 500-800 range, which is weak. It's a good time to work on your tan or fix that ding. There's a glimmer of hope Tuesday the 8th and Wednesday the 9th with a 1.3m swell and a long 16-second period, but it just doesn't come together for a top-tier day.
But then, hold on to your leashes, because Saturday the 12th is the gem of the first week. We got a 1.3m west-southwest swell at a super long 18 seconds – a proper groundswell. And the wind? A light southerly at 10 km/h, a perfect cross-offshore breeze. The energy is a solid 1319, and the call is for excellent conditions for those who know what they're doing. That long period means it's going to be lined up and sparkling. This is the day to make it happen.
The days after that, Sunday the 13th through Tuesday the 15th, are okay. Mornings keep their clean, cross-offshore winds, and we've got 1.4m of swell, but it loses the magic. The energy drops, and the afternoons get chopped up by sea breezes. It's surfable, but you'll be working for it.
Looking further out, and this is a long-range call so don't hold me to it, but Saturday the 19th is showing another pulse of strong west-southwest swell. We're talkin' 2.2m at 16 seconds, with a massive energy reading of 2463. That's a lot of water. But, just like the 6th, it's probably too big for Dunes. It'll be a sight to see, but only for the brave and the expert. The morning wind looks clean out of the south, but that size could be a problem.
After that big day, we fade back down to the 1.4m stuff on the 20th and 21st, with the winds doing the usual dance of clean mornings and bumpy afternoons.
So, my final word is this: Your best bet, the one that stands out above all else, is Saturday the 12th. That's the day the stars align for a truly memorable session. The 19th has the size and power, but it's a risky call for this break.
Remember, it's a reef out there, so that long-period swell is going to be right in its wheelhouse. Don't waste the good day, and don't beat yourself up during the flat spell. That's just how this place works.
Catch you in the water.

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.
