The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for Cunns.
We’re staring down a bit of a mixed bag. The first couple of days are a write-off – Sunday the 2nd looks messy with a moderate cross-shore breeze and a weird, choppy surface. Nothing to get excited about there. But then things clean up in a big way.
The standout window is Monday the 3rd. The morning is where it’s at. We’ve got a clean 6ft SW groundswell pushing through with a long 14-second period, and the wind is a light offshore from the SSE. That’s a recipe for some serious, lined-up waves at Cunns. The combined energy is solid (1273), so there’s plenty of push. This is expert-level stuff – too much for a beginner, but for anyone who knows what they’re doing, it’s going to be firing. The afternoon on Monday holds up nicely too, with a clean 5ft swell and a cross-off breeze.
Tuesday the 4th drops off a bit in size, dropping to 4ft, but it’s still clean in the morning with a NE breeze. Worth a paddle if you're desperate for a longer board.
After that, the wind starts to get messy again from Wednesday the 5th through to the weekend, with a lot of cross and onshore wind. The swell sticks around, but the quality goes out the window. That fresh cross-shore chop on Wednesday and Friday looks ugly.
The next real good window is Thursday the 13th of August. We get a 6ft SSW groundswell with a 13-second period and a clean offshore breeze from the ESE. That’s another excellent session for experienced surfers, and the combined energy is a punchy 1047. The morning is your best bet.
Friday the 14th is also a big one. We’re looking at a 7ft SW groundswell with a very long 17-second period and a gentle offshore from the E. That’s heavy, groundswell energy (2300) – perfect for a reef like Cunns, but it will be peaky. Definitely for the experts only. The period is so long that the sets will be spaced out, making the paddle out easier, but the waves themselves will be meaty.
The second week fades out with some cleaner, smaller, cross-off conditions from the 15th onwards, but nothing that’ll blow your socks off. The energy drops back to moderate levels.
Overall, get on it Monday the 3rd for the best mix of size and cleanliness, and circle Thursday the 13th and Friday the 14th for another run of top-tier, expert-only groundswell. The rest is mostly wind-slop or small.
Rusty.

Information about the Cunns Surf forecast
The above surf forecast table for Cunns provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cunns can be found by selecting the local surf guide option on the grey menu. Our Cunns 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 (Cunns) 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 Cunns 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.
