The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the local stretch. We’re looking at Dunes, a consistent reef break, exposed to the swell. The water temp is about average for the time of year, nothing unusual there.
The pattern starts with a bit of a gap - no real surf to get excited about on the first few days. The first standout is Friday morning, September 11th. It’s a glassy morning with a light 3 mph breeze from the northwest. The swell is 3 ft from the WSW with a period of 14 seconds, giving it a nice long-period groundswell feel. The combined energy is moderate, in the 476 range. This is clean, fun-sized surf for a Friday morning, but it’s not a huge standout. The afternoon turns into a cross-on mess, so get out early.
The real standout this week is Saturday morning, September 12th. This is the best on offer. The wind is offshore from the southeast at 9 mph, and the swell bumps up to 4 ft from the WSW, with a period of 18 seconds - that’s a very long period groundswell. The energy is strong, clocking in at 1416. That’s excellent surf for experienced surfers. The long period will make the waves push nicely, but Dunes being a reef, it should be lined up well. The offshore wind will keep it clean. Crowds are possible, so get in early.
Sunday morning, September 13th and Monday morning, September 14th offer clean, but marginal conditions with the swell around 4-5 ft. The wind is cross-offshore, so the waves will be clean, but the energy is moderate and the quality is questionable. Tuesday morning, September 15th is similar.
Wednesday morning, September 16th brings another good window. The wind is cross-offshore from the SSE at 9 mph, swell is 5 ft from the SW with a 14-second period, and the energy is moderate at 707. It’s clean and should be very good.
Thursday morning, September 17th still has some clean, 3 ft swell with offshore wind from the SE at 6 mph. Energy is weak-moderate at 431. It’s a decent morning session, but not as strong as the Saturday.
The following week starts to fade. Friday morning, September 18th is marginal, and the weekend of September 19th-20th sees a bigger pulse of 6-6 ft swell from the WSW, but the winds are cross or cross-off, and the quality is marginal. On Saturday, the swell is over 5 ft, so it’s getting punchy for beginners, but the wind is messy. By Sunday, it’s still a bit lumpy.
The next real bright spot is Tuesday morning, September 22nd. The wind is glassy from the southeast at 3 mph, and the swell is 4 ft from the SW with a nice 16-second period. The energy is moderate at 661. This is a very good, clean morning, but it’s more than a week away, so keep an eye on it - long-range forecasts can change.
After that, it’s a slow fade into the end of the month with small, choppy surf and poor conditions. The last week is mostly a bust.
So, for the best on offer, I’d pick Saturday morning, September 12th. That’s the one with the most punch, cleanest wind, and best energy. The Tuesday morning, September 22nd is also a promising one to watch for later.
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.
