The Lowdown

Righto, Rusty here. Let’s have a look at what’s on offer at Dunes, because this is the only spot that’s popped up for the next 16 days.

Alright, so the first real chance to get a wave is on Tuesday, the 1st of September. It’s a morning session that’s the pick. We’ve got a clean 5ft swell rolling in from the WSW, and that’s a sweet long-period groundswell at 16 seconds. The wind is a light cross-off from the SSE, so the face will be tidy. The water’s sitting at 74°, which is pretty much bang on average for this time of year, so nothing weird there. The combined energy is moderate (1136), so there’s a bit of push behind it. This is a reef break, and it’s consistent, so you don’t have to be waiting around forever. It’s an exposed spot, so it picks up the SW swell well. This is the standout session for the whole run – it’s not perfect, but it’s the best we’ve got.

The afternoon on the 1st is a write-off though. The wind swings to the SW and picks up, making it a cross-chop mess. Poor conditions.

Wednesday the 2nd and Thursday the 3rd both have marginal morning surf with clean conditions and 4ft swell, but the period drops a bit, and the energy is weak (574 and 490). You *could* get a few, but it’s not going to be memorable.

Friday the 4th morning is a no-go – fresh offshore breeze but the paddle-out will be a mission. The afternoon has a bit more life, but it’s still marginal.

Saturday the 5th morning is a similar story: clean, but small at 3ft, and the energy is moderate (688). The afternoon is blown out.

Sunday the 6th morning has a strong offshore breeze (25 mph) from the SSE. That’ll keep it glassy clean, but it’s a tough paddle into that wind. The swell is 4ft, but the period is a solid 14 seconds. The energy is moderate (521). It’s a tricky one – clean but hard work.

Monday the 7th morning is a surprise. The swell jumps to 4ft from the SW, period is 13 seconds, and the energy is moderate (1013). The wind is a cross-off from the ESE. That’s a decent combo for a reef break. The afternoon is a no-go with onshore wind.

Then we hit a bit of a lull. From Tuesday the 8th through to Friday the 11th, the mornings are all similar: clean, 4ft to 4ft, moderate energy, but nothing really exciting. The afternoons are mostly poor or marginal with onshore winds.

Now, Saturday the 12th morning is another standout. The swell is 3ft from the WSW, but it’s a very long-period groundswell at 17 seconds. The wind is a light cross-off from the SSE. The energy is moderate (736). That long period will wrap in nicely on this reef, making for some proper, organised lines. The water temp is still mild. It’s a really good option for a morning session.

Sunday the 13th morning is back to marginal, but Monday the 14th morning is a beauty. The wind is offshore from the SE, 4ft from the SW, 14 second period, and moderate energy (597). That’s a clean, empty-looking lineup.

Tuesday the 15th morning is also solid: clean, 4ft, 15 second period, and light cross-off breeze. The energy is moderate (628).

And finally, Wednesday the 16th morning is the last real highlight. The wind is a light cross-off from the SSE, the swell is 4ft from the SW, period is 14 seconds, and the energy is moderate (595). It’s a clean, friendly morning session.

So, overall, the best on offer are the Tuesday the 1st morning, and then the Saturday the 12th morning, Monday the 14th, Tuesday the 15th, and Wednesday the 16th mornings. The mornings are the only game in town here; the afternoons are toast almost every day. This is a consistent reef break, so there’s always a chance, but you’ve got to pick your windows.

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.
