Alright, Rusty here. Let's talk about what's coming up for the Dunes. This is a reef setup, exposed to the southwest swell, so it needs the right angle to light up. We've got a bit of a slow start to the forecast period, but there are some bright spots further out.

The ocean is holding a solid 75° water temperature right now, which is bang on average for this time of year, so you won't need a thick steamer.

The first real chance for a wave comes through on Thursday the 10th of July. Friday morning has a clean offshore wind from the SSE at 12 mph, pushing into a 4.6ft WSW groundswell with a nice long 14-second period. The combined energy is moderate at 851. It won't be huge, but that offshore breeze will have the waves standing up nicely. That's the pick of the first week, no doubt.

Through the weekend and into the following week, the size drops right off. We're talking knee-to-waist high at best, with the wind mostly cross or cross-off. On Monday the 13th, the swell period jumps to 18 seconds, which is a very long groundswell, but the height is only 3.6ft. That kind of period can make a reef setup like Dunes really start to talk, but it might also make the sets a bit fat and hard to read. It's worth a look, but not a standout.

Things get interesting again on Friday the 17th of July. A bigger pulse of SW swell rolls in, pushing 4.9ft in the morning and building to 5.6ft in the afternoon, with a 16 to 17-second period. The wave energy jumps up to strong with a combined reading of 1573. The wind is a moderate E breeze, keeping it clean. This is solid, powerful surf. At that size, it's probably one for the experienced crew only.

The absolute best of the bunch, though, looks like Saturday the 18th of July. The morning session is the winner. You've got a 5.2ft SW groundswell at 15 seconds and a super light cross-off breeze from the ESE at only 6 mph. The water will be glassy. The energy is strong, sitting at 1137. This is excellent quality surf for those who know what they're doing. The afternoon will get a little cross-onshore, so the morning is the go. Just be aware, Dunes can draw a crowd sometimes.

After that, it fades again through Sunday and into the last few days. The final day, Wednesday the 22nd of July, finishes with a tiny 3.3ft SW swell, but it's glassy in the afternoon. No power in it, but a pretty way to end the run if you just want to bob around.

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.
