Alright, Rusty here, gonna break down the Dunes forecast for the next couple weeks.

The water’s about 76°F, pretty much normal for the time of year. Nothing wild there.

We start off a bit slow, but the real gem is Saturday, July 11th. Dunes is a consistent reef break, exposed to the SW swell. Saturday morning has a clean 3ft of WSW swell with a moderate offshore SSE breeze at 15 mph – that’s proper offshore, so the faces will be smooth. Then Saturday afternoon goes totally glassy with no wind and 3ft of clean WSW swell. The combined energy is moderate (229), but that glassy water is a major win. That’s the best early session.

Sunday the 12th still has some waves, but the morning offshore (ESE 9 mph) is gentle, and the swell drops to 2ft. It’s surfable, but not a standout.

Now, mark your calendar for Saturday, July 18th. That morning is the absolute standout of the whole forecast. The swell bumps up to 4ft from the WSW, with a gentle offshore SE breeze at 9 mph. The combined energy is a solid 587 (moderate) and the forecast is for very good surf. Clean offshore wind and a reef setup – that’s the recipe. Crowds are sometimes a thing here, so with a call like this, expect a few.

Then Sunday the 19th, the swell gets bigger – 6ft from the SW in the morning, with a 17-second period. That’s a long-period groundswell, meaning more energy (2086 combined energy – strong) and better shape, but it’s getting into the “experts only” range. The wind is cross-offshore, so it’ll be clean. Still, that Saturday morning is the one to lock in.

After that, the swell fades into the end of the third week and the fourth week, with smaller 2ft to 3ft waves. There are some clean offshore mornings on the 23rd and 24th of July, but the size is small. The 25th of July morning has a bit more at 3ft from the WSW with a 15-second period and offshore wind – worth a look if you’re keen.

No major gaps in waves here, but the quality windows are tight. The Saturday, July 18th morning is the clear winner.

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.
