The Lowdown

Alright, Rusty here. Let’s talk about the stretch ahead at Dunes. This reef break fires when the swell comes in from the southwest. Water temp is about 76°F, which is pretty normal for this time of year.

The next few days are quiet. Tuesday the 14th has a clean 4ft SW groundswell with a 16-second period, but that cross-off wind is blowing 19 mph, and the energy is moderate (661). It’s okay, but nothing special. Wednesday and Thursday are similar – small, clean mornings but the waves are weak. Thursday afternoon the 16th is a bust.

Now, here’s the payoff. Sunday the 19th is the standout. A solid 6ft SW swell hits with a 15-second period and strong energy (1380). Morning offshore wind from the southeast at 16 mph keeps it clean. This is serious surf – over 5ft, so it’s for experienced riders only. Then Sunday afternoon goes glassy calm, with the swell still at 5ft. That’s as good as it gets.

Monday the 20th is still quality. Clean 4ft swell in the morning with offshore wind, and the afternoon goes glassy again, though the swell drops to 4ft.

After Monday, it fades. The rest of the run is small, weak, and inconsistent. There are a few clean mornings with offshore wind on the 23rd and 26th, but the swell is barely 3ft. The last week is flat and messy. From the 27th on, it’s a long stretch of hardly any waves.

Bottom line: the first week is slow, but Sunday the 19th and Monday the 20th are your best bets. Don’t sleep on it, because after that, it’s quiet for a while.

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.
