Table - best surf conditions forecast for Dunes over the next 16 days.
Alright, Rusty here. Let’s break down what the ocean’s got for us.
Water temp is around 76°, pretty average for this time of year. First real highlight is Friday morning on the 10th at Dunes. It’s a reef break open to the SW, and we’re looking at a clean 5ft SW groundswell with a long 15-second period and light offshore winds from the SE. The combined energy is moderate (863). This is a nice, well-shaped wave for intermediates and above.
The weekend drops off quick – Saturday the 11th fades to 3ft in the morning and goes flat and messy by afternoon. Sunday the 12th is tiny with 3ft waves and weak energy (199). Not worth suiting up.
There’s a gap of a few days where it’s either too small or blown out. Monday the 13th has a 2ft SW groundswell with an extra-long 18-second period, but it’s just too small to get excited about.
Now, mark your calendar for Sunday the 19th – that’s the real standout. We’ve got a solid 5ft SW swell, long 16-second period, and moderate offshore SSE winds at 16 mph. The combined energy is pumping at 1271. Clean and powerful, but that size is for experienced surfers – beginners should sit this one out. The afternoon holds similar energy with cross-off winds.
Monday the 20th goes even bigger: 6ft to 7ft SW swell, 17-second period, and fresh offshore winds from the SE and SSE. Energy readings are high (1984 to 2161). This is expert-only territory – big, clean, and powerful.
The swell backs off through the 21st and 22nd, but Wednesday the 22nd afternoon turns glassy with a 3ft SW swell and no wind – perfect for a relaxed session, though the energy is low (273).
Best bets: Friday morning the 10th for a clean fun wave, and Sunday the 19th through Monday the 20th for the real size and punch. Crowds at Dunes are possible on the better days.
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.
