The Lowdown
Alright, surfers, Rusty here. Let’s have a good look at what Dunes has in store for us over the next couple of weeks. It’s a mixed bag, for sure, but there are definitely a few windows where it could be worth getting wet.
The first few days are pretty average. We’ve got some chest-high swell rolling in, around 4ft, but it’s just not coming together. Mornings are clean with offshores, but the afternoons get chopped up. Water temp is 74°, which is just about normal for this time of year.
Tuesday morning (Sept 8) will be clean and offshore, but it’s just a so-so 4ft. The period is a solid 16 seconds, so there’s energy, it’s just a bit messy. That swell energy is moderate, reading 886.
We’re in a bit of a lull from Wednesday through Friday as the swell backs off a touch to 3ft. The winds go onshore and cross-shore, making things pretty junky. It’s a classic wait-for-it period.
The first real standout comes on Saturday morning, September 12. The swell fills back in to a better 4ft but with a longer, more powerful period of 18 seconds and the energy is jumping up to 1387. Winds are light offshore from the SSE. This is the first time it all clicks. The waves will be clean and lined up with that long-period SW groundswell.
After that Saturday morning high, it gets a bit messy again. Sunday morning is rideable, but the winds are up. Monday morning, Sept 14, looks like another clean one with light offshore winds and a 5ft swell, but the period has dropped back to 14 seconds. Not as strong as Saturday's dawn patrol.
The second week is less exciting overall. The pattern is the same most days: clean-ish mornings, blown-out afternoons. We’ve got a long stretch of average surf from Sept 17 through Sept 22. Swell heights hover between 3ft and 4ft, and the mornings often have some kind of offshore or cross-offshore breeze, making them clean and ridable, if a little gutless.
Then, the biggest swell of the period shows up on the horizon. On Wednesday morning, September 23, the model shows a jump in swell size to 5ft from the SW, with a 16-second period. The energy is up there, with a strong 1164 reading. It looks like the wind might just be starting to get messy though, so it’s a promising one, but we’re far enough out that I wouldn’t bet the farm on it just yet.
Look, the conditions are pretty inconsistent for the next two weeks, so pick your moments. The clear standouts are Saturday morning, Sept 12, and to a lesser degree, Monday morning, Sept 14. If you can only get out once, make it the 12th. Expect some crowd potential on a clean Saturday morning like that.
Signing off.
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.
