Table - best surf conditions forecast for Dunes over the next 16 days.
The Lowdown
Alright, let’s talk Dunes. It’s a consistent reef break that gets plenty of southwest swell, but the next couple of weeks are gonna be a real mixed bag. Water temp is about normal for the season.
The first real standout is on Tuesday, 18 August. The morning session is looking prime. We’ve got a clean 5ft swell from the southwest with a solid 17-second period – that’s a proper groundswell. The wind is light offshore, glassy, and the combined energy is a strong 1353. This is going to be excellent for experienced surfers, as the size is pushing into the big stuff. The afternoon gets choppy and onshore, so get it while it’s clean.
Then on Wednesday, 19 August, the swell jumps to 7ft from the west-southwest. The morning is clean with a cross-offshore breeze, but the size is too big for this break. The combined energy hits 2075, which is very strong, but it’s a warning. This is expert-only territory, and even then, it might be a washout. The afternoon gets a bit messy, but the morning is for the brave.
Thursday, 20 August, also has a good morning with a 6ft southwest swell, clean offshore winds, and strong energy (1523). Again, for experienced surfers only.
Things ease off after that. There’s a long stretch from the 21st through to the 27th where the conditions are marginal or poor. The wind is often strong or cross-shore, and the swell drops. The 22nd does have a notable 23-second period swell in the morning, but the height is only 2ft, so it’s small and clean but not a standout due to the lack of size. The energy is still moderate (1005), but the wave size is just too small for a proper session.
Overall, the best bet is the Tuesday, 18 August morning – that’s the one to circle on the calendar. Clear, clean, and proper groundswell. Get ready for it.

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.
