The Lowdown

Right, let’s see what Dunes has cookin’ for the next couple weeks.

The first couple days are kinda sluggish. Tuesday morning has 5ft of SW groundswell with a 14-second period, and combined energy around 761 (moderate). The cross-off wind keeps it clean but it’s not screaming. Tuesday afternoon gets a bit sloppy with a stronger cross breeze.

Wednesday morning (16th) is the first real bright spot. Swell drops a little to 4ft, still SW, same long 14-second period, and with a light SSE breeze, it’s clean and shapely. The energy reading is 743 (moderate) and conditions are looking very good. This is my pick for a sneaky midweek session.

Thursday morning (17th) cleans right up with a slight offshore breeze and a 3ft SW swell, period 13 seconds. It’s small but tidy – a longboard or fun fish will love it. Energy is lower at 378 (weak), but the quality is there.

Friday (18th) drops right off – tiny 2ft and messy afternoon wind. Not worth rushing.

Now, Saturday 19th morning is the standout of the whole outlook. A solid 7ft WSW groundswell, with a long 16-second period, pumping in with a clean offshore breeze. Combined energy is 1982 (strong to very strong). This is excellent surf, but it’s pushing into expert territory. The afternoon gets even bigger at 7ft, but the wind goes cross and energy hits 2193, so only for the experienced. If you’re solid, Saturday morning is the one.

Sunday 20th morning is still fun at 6ft WSW, period 14 seconds, with a cross-off breeze and energy of 1127 (moderate). The afternoon gets wind-affected again.

Through the next week, things settle back into smaller, cleaner windows. Monday 21st through Wednesday 23rd mornings all offer clean but modest surf, mostly around 3ft to 4ft, with moderate energy and tidy conditions. Nothing huge but still fun.

Thursday 24th morning bumps back up a little to 5ft SW, but the afternoon wind cranks to 25 mph cross, so morning is the only window.

Friday 25th morning has a punchy 5ft SW swell with a strong breeze cross-off, energy hitting 1007 (moderate) – clean but challenging.

Now, another potential highlight: Saturday 26th morning and afternoon both offer 5ft SW groundswell, but the afternoon has that lovely offshore breeze, 18-second period, and energy of 1327 (strong). That’s a beautiful combo, especially for a reef or point. The morning is cleaner but with a stronger wind. This is a solid option for experienced surfers.

The last few days (27th to 30th) drop off again, but Tuesday 29th morning has a clean 3ft SW swell with a 14-second period and energy of 390 (weak). It’s small but clean. Wednesday 30th morning also looks very promising with a 4ft WSW groundswell, 15-second period, and a moderate offshore breeze, energy 674 (moderate). Conditions should be very good then.

Crowds at Dunes can pop up sometimes, so if you hit a clean morning with light wind, you’ll be stoked.

There are gaps in the smaller afternoons, but the mornings are where it’s at. The standout sessions are definitely Saturday 19th morning and Saturday 26th afternoon for the bigger, cleaner, more powerful stuff. Midweek mornings offer smaller, cleaner options.

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.
