The Lowdown
Alright, Rusty here again. Let’s talk surf in feet and degrees.
We’ve got a steady run of waves at Dunes, but you gotta pick your sessions wisely. The first real window opens Sunday morning with chest-high swell running from the WSW, about 4 to 5 feet at a 15-second interval – proper long-period groundswell. Combined energy sits at a solid moderate level of 897. Water temp is 75°, right about normal for the season. A light cross-off breeze from the SSW keeps the surface clean.
The standout is Saturday, September 19th, in the morning. That’s the one to circle. Swell around 5 to 6 feet from the WSW at 16 seconds – that’s long, powerful groundswell. Wave energy jumps into a strong range at 1409. With a light cross-off wind from the SSE, it’s clean and lined up. This is for experienced surfers only – too big for beginners. That afternoon sees the swell jump to nearly 7 feet from the same direction, but with a cross wind making things messy and heavy. Only for the brave.
Sunday the 20th morning also delivers. Waist to chest-high swell at 5 feet from the WSW, 14-second period, moderate energy at 1014, and clean conditions with light cross-off winds. A solid session for experienced folks.
Now, the afternoons are generally a bust. Winds crank up from the SW or WSW, hitting 20 to 28 mph, and the surface turns into lumpy chop. From the 22nd through the 28th, the swell drops to around 3 feet. Mornings stay clean but small, and afternoons are still blown out. Not much to write home about.
Remember, Dunes is a reef break, consistent and exposed to the SW swell. Expect crowds sometimes. Those long-period swells on the 19th and 20th are perfect for a reef setup – they’ll draw up nicely.
So, your best bet: Saturday morning, September 19th. Sunday morning the 20th is another good shot. The rest? Clean mornings with small waves and afternoons to take off.
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.
