The Lowdown

Alright, Rusty here again, switching over to feet and miles.

Let’s be straight: the next couple of weeks at Dunes are a mixed bag. We’ve got a steady little Southwest groundswell, but the wind is the main character in this story. The water’s running about 76°, which is normal for the season.

The pattern is mostly frustrating. There are moments when the wind gives up, but the swell stays small. Wave energy is mostly in the 150-400 range, which is just moderate. The swell period is decent, often 13-15 seconds, so it’s real groundswell, but with the wave height barely scraping 2ft for the first week, there’s not much to work with.

Thursday the 23rd and Friday the 24th are nothing special. Morning winds are a fresh 19 mph cross-offshore, tearing the surface up. Friday the 24th afternoon does offer a bit of hope with a light, glassy north wind and clean lines, but the swell is only 2ft. Surfable, but very ordinary.

The first real moment comes on Tuesday the 28th of July. The swell picks up to 3ft from the Southwest with a 13-second period, and the combined energy jumps to 352. The morning has a moderate cross-offshore breeze, keeping it clean. It’s not epic, but it’s the best we’ve had so far.

Things fire up from the 3rd of August. Monday the 3rd of August sees the swell hit 5ft from the Southwest with a long 17-second period. Combined energy is 1148, which is strong. The morning has a gentle cross-offshore wind keeping it clean. This one’s worth getting to. The size is solid for intermediate surfers, but the long period (over 15 seconds) can make it a bit straight at a beach break. Dunes is a reef though, so it should handle it fine.

The absolute standout is Thursday the 6th of August. The swell stays at 4ft from the Southwest with a 14-second period, and the afternoon goes glassy with a 3 mph north-northeast breeze. That’s the kind of wind you wait for. Combined energy is 639 (moderate-strong), and conditions are expected to be very good. This is the one to circle on the calendar. Dunes is consistent but can get crowded, so plan to get in early.

Beginners should watch out when it’s over 5ft. Most days are fine, but Monday the 3rd and Thursday the 6th are for the experienced crew.

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.
