The Lowdown

Alright folks, Rusty here. Let's have a look at what we've got cookin' for the coming weeks. The only game in town for this stretch is Dunes, so we'll be riding that wave, so to speak.

First up, the water temp is sitting at a pretty normal 75° for this time of year, so no surprises there. The outlook starts with a bit of a wait, though. The first decent session isn't until Monday morning, the 14th. Sunday afternoon is a write-off with a strong cross-breeze chopping everything up. So, hold your horses 'til Monday.

Monday the 14th and Tuesday the 15th offer some clean morning windows with a light cross-offshore breeze and a 4ft to 5ft SW swell, but the energy is moderate and the conditions are only really rated as marginal. It's surfable, but nothing to write home about.

Then we get to Wednesday morning, the 16th. Now we're talking. The wind swings light offshore from the SE, cleaning up a 4ft SW swell with a 14-second period. This is a solid, punchy groundswell that will work well at this reef setup. The combined energy is moderate (743), and the forecast is for very good conditions. This is the first real standout of the period, and it's the best we'll see for a while. Crowds are sometimes an issue here, so if you can get out early, you'll be rewarded.

Thursday the 17th and Friday the 18th mornings are also decent, with clean 3ft and 2ft swells respectively. Friday morning is absolutely glassy, which is a beautiful thing, but the swell is tiny. Fun for a longboard, maybe.

Now, hold onto your board. Saturday the 19th afternoon sees a big pulse of energy, with a 7ft WSW swell cranking at 16 seconds. The combined energy is very strong (2837). This is big and powerful. For a reef break, this is going to be heavy, and it's only for experts. The wind is cross-shore, so it won't be perfect, but the raw power is undeniable. This is the other standout, but you need to know what you're doing.

Sunday the 20th morning cleans up nicely with a cross-offshore breeze and a 5ft SW swell (895 energy), giving us very good surf. A great follow-up to the big day.

The following week from Monday the 21st through to Monday the 28th is a mixed bag of smaller swells (2ft to 4ft) and tricky winds. The mornings are often the cleanest, especially with light offshore breezes. There are a few promising moments: Tuesday the 22nd morning has a 4ft SW swell with a long 15-second period (583 energy), and Sunday the 27th morning has a 3ft SW swell with a very long 17-second period (629 energy), described as very good surf. Then Monday the 28th morning is glassy again with a tiny 3ft swell.

Overall, the best bet is Wednesday morning the 16th for a clean, solid session. For the big-wave hunters, Saturday the 19th afternoon is your window, but be warned, it's a beast. For the rest of the time, keep an eye on those clean morning windows for smaller, more manageable waves.

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.
