The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Dunes.
Alright, the first thing I’m seeing is that we’ve got a bit of a wait for the real good stuff. The first few days are a bit of a tease. Wednesday the 29th and Thursday the 30th are a write-off – small swell at 2.6ft, and the wind is just not playing nice, keeping things messy. We’ll see a little improvement on Friday morning the 31st, with a light offshore breeze cleaning up that same 2.6ft SW swell. The period is a very long 16 seconds, so it’s a proper groundswell, but it’s small. It’s a starter, a sign of life.
Then Saturday the 1st of August looks like the first real standout. The swell bumps up to 3.6ft from the SW, and we’ve got a moderate offshore wind from the ESE. That’s going to put some clean lines on it. The combined energy is moderate at 657. It’s a reef break, so it can handle that long period without getting too straight. If you can get out Saturday morning, you’ll be in for a treat.
The middle of the week gets a bit flukey again with onshore winds, so we’ll have to sit tight until Tuesday the 4th of August. That morning is a real gem. The wind goes completely glassy, with a 3.3ft SW swell. The combined energy is moderate (472), it’s clean, and it’s a reef, so it should be peeling nicely. It’s a sneaky good session.
The following week is where the size comes in, but with a catch. The morning of Saturday the 8th of August, we’re looking at a solid 5.2ft SW swell with a moderate cross-offshore wind. The energy is up there at 1147 (strong), and it’s clean. This is expert territory at that size for a reef break. The real highlight, though, might be Tuesday the 11th of August. There’s a 4.9ft to 5.2ft SW swell – still in the expert zone – but the Tuesday afternoon session is looking absolutely perfect. The wind goes glassy, the energy is a powerful 1312, and the notes say it’s excellent for experienced surfers. That’s the one to circle on the calendar.
Keep in mind, Dunes can get crowded sometimes, so for the best windows, you’ll want to be out early. The water temp is about 74.8°, which is pretty normal for this time of year.
Alright, I’m signing off for now. Get in the water when you can.

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.
