The Lowdown

Alright folks, Rusty here. Let’s have a look at what Dunes has in store for us.

Right off the bat, Dunes is looking like a solid go-to over the next 16 days. It's a consistent reef break that’s exposed to the swell, and we’ve got a nice run of clean conditions early on to kick things off. The water temp is sitting at 74°, which is about average for this time of year, so no surprises there.

We start strong this Thursday morning, the 10th. The sky is clear, wind is glassy from the southeast at 3 mph, and we’ve got a 4ft groundswell rolling in from the WSW with a period of 15 seconds. The wave energy is moderate (771), and the conditions are set to be really clean. This is a great window for anyone.

Thursday afternoon the wind swings onshore from the NW at 9 mph and it’s game over for the day. Friday morning, the 11th, is another beauty though. Glassy conditions again with a light WNW wind at 3 mph, a 3ft swell from the same direction, and the energy is still moderate (513). The wave comment says expect very good surf, and I’d agree. It’s a morning mission.

Friday afternoon gets chopped out by a cross-onshore W wind at 12 mph.

Now, the standout for the first week is Saturday morning, the 12th. We’ve got a clean 4ft swell from the WSW, a long period of 18 seconds, and a light offshore SSE breeze at 6 mph. The combined swell energy jumps up to a moderate 1383, and the wave comment says it’s excellent for experienced surfers. That long period means the waves will have real shape and power, and with offshore wind, it’s going to be clean and lined up. This is the pick of the week for sure. The afternoons turn to mush with a cross-onshore breeze.

Sunday morning, the 13th, is still good with 5ft swell and clean cross-offshore wind, but the energy drops a bit (886). Still a solid session.

We hit a bit of a rough patch from Monday the 14th through the middle of the week. Mornings are marginal or just okay, and the afternoons are blown out by strong cross-shore winds. The swell hangs around 4ft to 5ft but the quality isn't there. Tuesday morning the 15th is clean but still only marginal.

We get a reprieve on Wednesday morning the 16th with a 5ft swell and clean offshore wind from the SSE at 6 mph. Energy is moderate (725). Another good dawn patrol. Thursday morning the 17th is similar with a clean 4ft swell and a 16-second period. The energy is a touch lower (739), but the conditions are clean with offshore wind.

The weekend of the 19th and 20th sees the biggest swell of the forecast. Saturday morning the 19th has 5ft from the WSW, and the combined energy is a strong 1189. But it’s only rated as marginal, likely due to a cross-offshore wind that’s a bit fresh. Saturday afternoon hits 6ft with a whopping 1637 energy, but it’s being hammered by a 19 mph cross-shore wind, making it a lumpy mess. By Sunday morning the 20th, the swell is a solid 7ft (1522 energy), but the wind is light and cross-shore, creating ripples. At this size, it’s only for the experts, and the conditions are only marginal. Honestly, with the wind and size, this setup looks more interesting for kite surfing than paddle surfing unless you’re really keen.

We finish the run on Monday the 21st and Tuesday the 22nd with clean mornings again. Monday has a 4ft swell with light cross-offshore wind, and Tuesday has a 4ft, 16-second groundswell with clean conditions. Good morning surfs to end it on.

Best on offer: Saturday morning, the 12th of September, is the clear standout. Clean, long-period groundswell with offshore wind at a moderate size.

After that, Thursday the 10th and Friday the 11th mornings are excellent, and Wednesday the 16th and Thursday the 17th mornings are solid runners-up.

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.
