The Lowdown
Alright, this is Rusty, and I’m talking from the Dunes. It’s a reef setup, consistent, intermediate-level right from the start. Water temp is sitting at 75°, which is pretty standard for this time of year, nothing out of the ordinary.
The next 16 days have a bit of a mixed bag, but there are some real highlights if you pick your windows. The action starts Thursday morning, August 27th. We’ve got a solid 7 ft swell rolling in from the WSW, with a long 17-second period. That’s a proper groundswell, packing serious energy (2127). The wind is a light cross-off, so expect clean, lined-up waves. This is excellent for experienced surfers. The energy is strong, but with that period, sets will be a bit more spaced, making it easier to get out the back. The swell drops a touch Friday morning, August 28th, to 5 ft from the SW, but with a fresh offshore from the SSE, it’s still clean. The energy is moderate (1031). The afternoon on Friday gets a bit messy.
Now, the standout for the whole period is Sunday morning, August 30th. Swell is down to 3 ft from the SW, but the wind is glassy – a light southerly at 3 mph. The period is back up to a very long 17 seconds, keeping the shape clean. The energy is moderate (545), but it’s going to be ridiculously clean. This is your best bet for a super fun, user-friendly session.
A few other mornings are worth noting: Monday morning, August 31st, sees 4 ft of SW swell with a 16-second period and light cross-off winds, giving clean surf and strong energy (1109). Tuesday morning, September 1st, is also decent with 5 ft and cross-off winds. The second week shows a few promising mornings too, like Sunday, September 6th, with 5 ft of SW swell and a fresh offshore, and Wednesday, September 9th, with 4 ft and light cross-off winds. The long-period swells in the second week will favour the Dunes as a reef break. There’s a gap of a few days at the end of the first week and into the second where the afternoons are poor, but the mornings are saving grace.
Looks like there’s no surf for the first few days of the forecast, so we’re picking up on Thursday. For the true standout, get on it early Sunday morning, August 30th – that glassy, long-period SW swell is going to be the best of the run.
Rusty, signing off.

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.
