Table - best surf conditions forecast for Cunns over the next 16 days.


Hey folks, Rusty here. Let’s cut right to it – the surf at Cunns is gonna take a while to get its act together. The first several days are plagued by cross-onshore winds and lumpy conditions, so you’ll be sitting on your hands for a bit. But there are a couple of windows that’ll make it worth the wait, especially for you experienced surfers.

The first real standout is Thursday, July 15th. That morning the wind goes glassy – dead flat calm – and the swell is a solid 6ft from the SW with a 15-second period. That’s a proper groundswell with moderate energy (1381). Expect some power and shape, but at that size it’s strictly for the pros. The afternoon cleans up even more with a light cross-off breeze and 5ft swell. Cunns is a reef break that doesn’t fire all the time, but when it does, it’s a gem.

Next up, Friday, July 17th in the afternoon – glassy again, with a smaller 4ft swell from the SW, period of 14 seconds. It’s much more approachable and the conditions are very good. A solid choice if you want something less intimidating.

Jump ahead to Thursday, July 23rd and Friday, July 24th. The swell builds back up, hitting around 8ft on the Thursday from the SW with a very long 16-second period – strong energy (3854). That’s a big, powerful groundswell. The Friday morning looks the pick though: glassy winds, 7ft SW swell, and excellent conditions for experienced surfers (energy 1669). This is a promising long-range prospect, but being more than a week out, keep an eye on it – if it holds, it’ll be a cracker.

For everything else, there’s a lot of cross-onshore breeze and choppy slop that’ll mess up the waves. The water temp is about average, nothing wild. Remember, anything over 5ft is getting big for beginners, and over 8ft is expert territory only.

Final word: the 15th and the 24th are your golden tickets. The rest is mostly a write-off. Pick those glassy windows and you’ll score.

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.
