The Lowdown
Alright, Rusty here. Let's get into it.
The next couple of weeks are looking mostly small and wind-affected, but there are a couple of moments that could really shine. The standout is early morning on Sunday, August 2nd, with a cleaner, more powerful option showing up again from the Tuesday the 28th.
We start off with a bit of a mixed bag this week. Tuesday morning the 21st has a clean 4ft SW swell at Dunes (reef), with a fresh offshore breeze from the SE. The water's sitting at 76°, which is about normal for this time of year. The combined energy is moderate (379). If you can get out before the wind picks up, it's a solid option. The afternoon drops to 3ft but stays clean.
Wednesday the 22nd sees the swell drop right off to 2ft. The morning is clean but very small. The afternoon goes glassy, which is a huge plus for the tiny 2ft waves – it'll be clean but you'll be scratching for any push. Thursday the 23rd is a write-off: fresh cross-off winds in the morning and a cross-on in the afternoon, all with tiny waves. Friday the 24th is similar: fresh morning winds, then a glassy afternoon with only 2ft on offer. Saturday the 25th and Sunday the 26th are essentially the same story – small, clean options but nothing with any power.
Monday the 27th is a no-go with a cross-shore breeze and a weak 2ft wave. Now, Tuesday the 28th is a real bright spot. The morning shows a clean 3ft SW groundswell with a moderate offshore breeze from the SE. The combined energy is up to 251, and the 13-second period gives it some real shape. This is the pick of the first week.
Wednesday the 29th morning is also promising with a clean 2ft swell and light offshore winds, but the energy is lower. The afternoon turns into a cross-on mess. Thursday the 30th and Friday the 31st are blown out with strong cross-onshore winds, and Friday the 31st afternoon sees a jump in swell to 5ft but with a strong cross-shore wind and messy cross-chop – that's a kite-surfing day, not a paddle day.
The true standout of the whole outlook is Sunday morning, August 2nd. We've got a clean 4ft SW swell with a light cross-off breeze from the ESE. The winds will be light, making for clean, lined-up waves. The combined energy is a solid 617, and the 13-second period will give you plenty of push. This is the best on offer, no question. It's not huge, but it's clean and has some power.
Monday the 3rd of August is a washout: a 6ft SW swell with strong cross-onshore winds. That's heavy and messy. Tuesday the 4th and Wednesday the 5th of August see the swell drop to 5ft with moderate cross-off winds, so it'll be clean but the energy is still high (over 1000), so it's a more advanced, semi-challenging wave.
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.
