Table - best surf conditions forecast for Dunes over the next 16 days.
Alright, let’s break this down for you folks who think in feet and miles. This is Dunes, a reef setup that faces the southwest. The water temp is sitting around 76°F for that first real session, which is pretty much what you’d expect for this time of year. No major surprises there.
Saturday the 11th is a write-off. Small, weak 3ft swell from the WSW, breeze messing it up. Energy is low (229). Skip it.
Sunday the 12th, the morning is your go. Wind goes offshore from the ESE, cleaning the face. Swell is small at 2ft, but it’s a clean southwest groundswell with a 12-second period. Energy is still low (169), but it’s rideable and clean. Afternoon gets choppy again.
Monday the 13th gets better. Morning has clean 3ft surf, a 14-second period, moderate energy (452). It’s a good start to the working week. The afternoon bumps up to 4ft with a very long 17-second period, and the energy jumps to 686, but the wind goes cross-shore, so the surface isn’t perfect. The power is there.
Tuesday the 14th through Thursday the 16th is just okay. Swell holds around 4ft, sometimes smaller, with moderate energy in the 500-600 range. Mornings are clean, but the wind is strong, 12 to 18 mph. Surfable, but not special.
Friday the 17th is similar, 4ft swell from the WSW. Still just ordinary.
Here’s your first real standout: Saturday the 18th. The morning is a gem. Clean 4ft SW swell, a solid offshore wind from the SE. Strong energy at 588. Conditions are “very good.” That’s your session.
Then Sunday the 19th is the big day for the experienced crowd. Morning sees a solid 6ft SW swell with a 16-second period and a fresh offshore wind. The combined energy is very strong at 1631. That’s powerful, big-wave territory. The reef will handle it, but this is for experts only. Afternoon drops to 5ft with a light cross-on breeze.
The following week fades. Monday the 20th is clean in the morning but energy drops to moderate. Tuesday the 21st and Wednesday the 22nd are poor, small, and weak. Not worth the paddle.
We get one more pulse on Friday the 24th. The morning has clean 4ft surf, a 17-second very long period groundswell from the WSW, and a moderate offshore wind. Energy is strong at 1053. This is considered excellent for experienced surfers. Good power and lines on the reef. The afternoon gets to 5ft but with a cross-on wind, so go early.
After that, Saturday the 25th has clean 4ft surf in the morning, but energy drops. Sunday the 26th is small and weak to finish it off.
So, best bets: the morning of Saturday the 18th for a clean, solid session. The morning of Friday the 24th for the powerful, long-period groundswell. Sunday the 19th morning for the big, expert-only day. Crowds can show up here, so for those standout days, be on it early.

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.
