The Lowdown
Alright, listen up. We start Wednesday the 29th of July with a solid SW groundswell hitting Cunns. This is a reef break, for advanced surfers only, and it’s inconsistent, so you gotta be patient. Wednesday morning shows a 8ft SW swell with a long 16 second period, giving heaps of energy (2,896 combined). Water temp is 60°, pretty average for this time. Wind is a gentle S cross-off, so it’s clean. This is proper, but it’s not for the faint-hearted. Wednesday arvo drops to 7ft, still decent period, but the wind picks up and tide might mess it.
Thursday the 30th sees the swell ease to 5ft SW, still solid. Morning has a gentle ENE cross-off, clean. Thursday arvo the wind goes offshore from the SE, glassy – this is the pick of the first few days for a clean, manageable wave. Crowds are only sometimes here, so it’s a good one to chase.
Friday the 31st drops right off to 3ft and then 3ft. Wind goes cross and light, but energy is weak. Not worth it.
Saturday the 1st of August is a mess: strong north winds, lumpy, choppy. Sunday the 2nd hangs around 4ft to 5ft but onshore or cross wind, so it’s rough.
Here’s the real standout. Monday the 3rd of August, morning: 5ft SW swell, 14 second period, and the wind is almost glassy from the ENE at 3 mph – cross-off, clean. Excellent for experienced surfers. This is the one: decent energy (1,077 combined), solid period, and silky. Not for beginners though, it’s over 5ft.
Tuesday the 4th of August sees the swell drop to 4ft in the morning with messy cross wind, but the arvo shows a 3ft SW swell with a very long 15 second period and glassy conditions – fun little sets.
From Wednesday the 5th of August, it’s mixed. Swell stays around 4ft to 5ft, but wind is mostly cross or cross-on, often fresh, so quality drops.
From Saturday the 8th of August, the swell ramps up – 10ft to 10ft WSW/SW, but wind is onshore or strong cross. It’s big and powerful (energy over 3,300), but messy. This is only for experts, and it looks more like a kite-surfing setup, especially the 8th, 9th, and 10th of August.
Bottom line: if you’ve got the skills, go Wednesday morning the 29th for size, or Monday morning the 3rd of August for cleanest conditions with solid swell. The rest has some fun moments but a lot of wind.

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.
