The Lowdown

Hey, Rusty here. Let’s talk Dunes.

We’re starting off a bit flat. Sunday (23rd) morning has 4ft of SW swell, but a 25 km/h cross-offshore SSE breeze keeps things tidy. Water’s 75°, which is about a degree warmer than normal – comfortable. Energy is weak (521). Not terrible, but not a standout.

Monday morning (24th) is cleaner – 3ft WSW swell with a 16-second groundswell period, and a 25 km/h SSE offshore. Nice long lines, clean conditions. Energy moderate (635). Worth a paddle.

Tuesday morning (25th) is okay – 4ft SW, 13 seconds, clean with SE offshore at 20 km/h. Energy’s down (415). Morning only.

Wednesday morning (26th) stays clean – 3ft SW, 14 seconds, light 10 km/h SSW cross-off. Moderate energy (462). Sneaky fun.

Now Thursday 27th – this is the big one. Morning has 6ft of WSW swell with a 17-second period. Energy jumps to strong (1970). Winds are cross-off SSE at 25 km/h – clean. This is for experienced surfers only – it’s solid. Afternoon holds 6ft, still clean. Best of the week for size.

Friday morning (28th) is 5ft SW, 14 seconds, fresh 30 km/h SSE offshore. Clean and punchy (857 energy).

Saturday (29th) and Sunday (30th) drop off – small and not great. Monday 31st morning picks up again – 4ft SW, 16 seconds, clean with a gentle cross-off. Energy building (963).

Tuesday 1st September morning is the standout of the second week. 5ft WSW, 17-second groundswell, light 10 km/h SE offshore – glassy, clean, strong energy (1192). This is for the experienced crew – it’s proper. Get it before the afternoon wind.

The rest of the week is smaller, with clean mornings but nothing special. Monday 7th morning is clean and fun, but the afternoon brings a very long 21-second period groundswell that gets chopped up by a fresh cross-on. That kind of period is better at a point or reef.

The top calls are Monday 24th, Thursday 27th, and Tuesday 1st September. Thursday’s the biggest, but Tuesday 1st September has the best mix of size, period, and glass. That’s the one.

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.
