The Lowdown

Alright, let’s break it down. Dunes is seeing a solid stretch of swell over the next couple weeks, but the wind plays games. It’s a consistent reef break, intermediate level, and likes SW swell—which is exactly what’s rolling in. Water temp is around 74°F right now, pretty average for September.

First few days are a wash. Wednesday the 9th has a 4ft SW groundswell with 16-second intervals, but the morning wind is a stiff 16 mph cross-off, and afternoon turns onshore. Not worth paddling out. Thursday the 10th morning shapes up better—lighter ESE breeze, 4ft WSW swell at 15 seconds, cleaner but still not the standout.

The real gem is Saturday the 12th morning. Swell runs 4ft WSW with a 18-second period—long, powerful lines. Wind is light offshore from SSE at 3 mph, glassy. Wave energy hits 1383 (moderate-strong). That’s the session to plan around. Clean, the reef holds the long period nicely, and crowds are only sometimes, so you’ll have plenty of room.

Sunday the 13th morning is still clean, but energy drops a notch. Monday the 14th morning offers another clean window with 5ft WSW at 14 seconds, light SSW breeze—good but not epic.

Second week brings a spike. Saturday the 19th morning: 7ft WSW, 16 seconds, clean with a gentle cross-off (9 mph). Energy rockets to 2071 (strong). That’s expert territory—too big for most, but if you’ve got the chops, score early before the afternoon cross-shore wind ruins it.

Sunday the 20th morning – hold up. 7ft WSW, 14 seconds, offshore from SSE at 16 mph. The report says it’s actually too big for this break. Even with good wind, the size pushes the reef’s limits. Only the most experienced should even look at it.

After that, the pattern settles into clean mornings with 3–4ft SW swell, light winds, and afternoon seabreezes that chop it up. The 21st and 23rd mornings are fun but nothing special.

Best call for most folks: Saturday the 12th morning. Clean, long-period, proper shape. For the experienced crew: Saturday the 19th morning, but get there early. The rest are morning-only windows unless you’re happy with slop.

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.
