Table - best surf conditions forecast for Dunes over the next 16 days.
G’day, I’m Rusty. Let’s talk about what’s coming up at Dunes. This is a solid little reef setup that loves a good SW groundswell and it’s consistent, so you know it’ll be ticking over most of the time. The water’s sitting at 76° right now, which is pretty average for this time of year, nothing wild there. The overall pattern is a slow start, then a proper pulse of energy right around the middle of the period, and then it fades again into the second week.
Monday the 13th is when things start to look interesting. There’s a clean morning with light E cross-off winds and a 3ft SW swell, period hanging around 13 seconds. The combined energy is moderate at 447, so it’s not huge but the wind setup will make it feel way better. You’ll get a few clean little runners. Tuesday the 14th has more of the same energy but a stronger breeze, not as good.
The real standout is Sunday the 19th. Saturday the 18th afternoon is already a beauty—glassy conditions, NW wind, 4ft SW swell with a 13 second period, and the energy reading hits 585. That’s a proper good window of clean, glassy waves. But Sunday morning the 19th pushes it to the next level. We’ve got offshore SSE wind around 12 mph, a 6ft SW swell at 16 seconds, and the combined energy is strong at 1453. This is full-blown, solid groundswell with serious power. It’s one for experienced surfers—that size and period will push through fast, long lines. Dunes is a reef, so that long period is ideal, it’ll bend in nicely. The wind stays clean. If you can handle the juice, this is your session. Crowds are possible here sometimes, so get in early.
After that, things wind down pretty quick. Monday the 20th is still surfable but the wind picks up strong from the south. By Tuesday the 21st it’s dropping back under 3ft and the energy is weak. There’s a few more clean-ish mornings, like Friday the 24th, with a 3ft SW swell at 14 seconds and light E wind. Energy is back to moderate at 780, so it’s a worthwhile go-around if you missed the big one. Saturday and Sunday the 26th are just small and ordinary.
So bottom line: Saturday afternoon the 18th into Sunday morning the 19th is where it’s at. Any other time, check the morning windows for cleaner conditions, but don’t expect much after the 20th.
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.
