The Lowdown

Alright mates, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks at Dunes.

The next few days are a bit of a mixed bag with some decent swell but the wind is going to be a real factor. Keep your eye on Monday morning for the cleanest session of the first week.

We kick off this Sunday afternoon, the 19th of July. Swell is a solid 5ft from the SW with a lovely long 14-second period, giving it some real push. The wave energy is strong at 1034, but it’s a bit of a shame the wind is a cross-on from the north at 6 mph. It’s surfable, but far from perfect.

Now, Monday morning, the 20th of July, is the one to aim for. The swell drops a touch to 4ft, but the wind shifts to a clean cross-off from the SSE at 6 mph. This is going to be glassy and clean. The water temp is sitting at 76°, which is about average for this time of year, so no wetsuit needed for the warm-blooded among us.

The swell drops off through the middle of the week. Tuesday morning, the 21st, has a clean 3ft swell with a fresh offshore from the SE at 19 mph, but the energy is a bit weaker at 330. Tuesday afternoon though, the wind goes glassy. It’s only 3ft, but if you’re desperate for a glide, that’s your window.

From Wednesday the 22nd through to the end of the month, the swell gets small and inconsistent, mostly under 3ft. The wind is often onshore or cross-off, but there are a few glassy afternoons. The real story is the energy, which is weak, with values mostly in the 100-200 range. Nothing to get excited about.

There is a glimmer in the distance. The first couple of days of August bring a pulse. The 2nd of August (Sunday) has a 5ft swell from the SW with a 17-second period, and the energy is massive at 1241. The morning has a cross-off wind from the ENE at 22 mph, which is a bit fresh. The afternoon on the 1st of August is glassy with 3ft, but the 2nd afternoon is cross-shore. It’s a promising long-range call, but we’ll have to wait and see if it cleans up. The 3rd of August morning is also 5ft but with a heavy cross-off wind.

For the standout, I’d go with Monday morning, the 20th of July at Dunes. The 4ft SW swell at 14 seconds, with a light cross-off wind, will give you the best chance at a clean, lined-up wave. The energy is a solid 534, so there’s plenty of push. Just be aware that crowds are sometimes on the cards here.

There is a significant gap of poor surf from the 22nd of July right through to the end of the month. It’s a bit of a flat spell, but that’s how it goes sometimes.

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.
