The Lowdown

Alright, let’s talk about Dunes.

We’re starting off a little slow, but there’s some good stuff coming through. The first real session is on the morning of the 24th. Dunes is a reef break, consistent, exposed to the SW swell, and it needs a clean SE offshore wind to really shine. The water is a touch warmer than usual for this time of year, at 76°F, with a 2°F anomaly, so it’s a bit on the mild side.

Monday morning, 24th August – This is the top pick of the first week. Swell is 3ft from the WSW, but the period is a long 16 seconds, so it’s a proper groundswell with a lot of push. Winds are light and offshore from the SE, making for clean, lined-up waves. The combined energy is 652 (moderate), and the conditions are described as very good. There’s a chance of crowds here, so get there early.

Tuesday morning, 25th August – Still a solid call. Swell drops slightly to 4ft from the SW, period 13 seconds. Clean offshore again from the SE. Good conditions, but not as punchy as Monday.

Wednesday morning, 26th August – A bit smaller, 3ft from the SW, but with a light cross-offshore breeze from the SSW, it stays clean. It’s a good, cruisy session if you want a quieter one.

Thursday morning, 27th August – Now we’re talking. Swell jumps to 6ft from the WSW, period 17 seconds – that’s a very long period groundswell, which means energy and shape, but it can be a bit straight at the beach. However, Dunes is a reef, so it should handle it well. Fresh offshore from the SSE, clean, but the combined energy is 1947 (strong). It’s a powerful day, maybe a bit much for beginners, but for the experienced, it’s the standout of the first week.

Friday, 28th August, morning – Back down to 5ft from the SW, but still a fresh offshore from the SE. The conditions are clean, but the energy is moderate.

Saturday, 29th August – Drops right off. 3ft from the SW, poor conditions. A skip day.

Sunday, 30th August – Small and messy. 3ft from the SW, but the wind is cross-off from the ENE, making it clean but weak. Energy is 611 (moderate). Not worth jumping for.

Monday, 31st August – Tuesday, 1st September – There’s a bit of a pickup. Monday morning sees 4ft SW, 16 seconds, with clean cross-off wind. Tuesday morning has 5ft WSW, 16 seconds, and clean conditions. The energy is strong on Tuesday (1141). These are decent, but not the top tier.

Wednesday, 2nd September – Thursday, 3rd September – Lumpy and crossed-up. The wind turns onshore or cross-shore, and the quality drops. The swell is 4ft to 5ft, but it’s choppy. Skip it.

Friday, 4th September, morning – A real dark horse. Swell is 4ft from the SW, period 13 seconds, but the wind is gentle and cross-off from the SSW, making it clean. The forecast says very good conditions. Combined energy is 509 (moderate). This is a solid call if you’re around.

Saturday, 5th September – Sunday, 6th September – Wind picks up again, cross-shore and choppy. Swell holds around 4ft to 4ft, but it’s not worth the paddle.

Monday, 7th September, morning – Another standout. Swell is 5ft from the SW, period 14 seconds, with a moderate offshore from the SE. Clean, strong, and the energy is 872 (moderate to strong). This is the best looking call in the second week.

Tuesday, 8th September, morning – Still good. 5ft from the SW, period 13 seconds, light cross-off breeze from the SSE. Clean and very good conditions. Energy is 711 (moderate). A solid way to finish the run.

All in all, the best windows are Monday morning 24th August, Thursday morning 27th August (for the bigger, more powerful stuff), and Monday morning 7th September in the second week. The long period swells on the 27th and 31st mean the reef at Dunes will be the place to be, as it’ll handle the energy better than a beach break.

Stay safe, and get wet.

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.
