The Lowdown

Alright folks, Rusty here. Let’s get into it.

We’ve got a window of swell coming through Cunns, but it’s going to be a bit of a mixed bag. The water’s sitting at 60°, which is pretty much standard for this time of year, nothing wild there.

The first real action kicks off on Tuesday the 28th, but don’t get your hopes up. We’ve got a solid 6ft to 6ft swell from the SW, with a decent period, but the wind is a messy cross-shore. The energy is pumping hard (1402 to 1610), but it’s going to be lumpy and choppy. Not a day for a clean ride.

Wednesday the 29th is where it starts to show some promise. The swell jumps up to 8ft from the SW, with a long 16-second period. The wind swings SSE and turns cross-offshore, cleaning things up nicely. The energy is massive (3085). This is proper groundswell, solid and powerful. It’s a big wave, though, so this is strictly for the experienced crew. The sets will be fat and lined up, but at a reef break like Cunns, that long period should wrap in nicely. Thursday the 30th is a real standout. The swell drops to a more manageable 5ft, but the wind goes light and glassy. We’re talking offshore breezes from the SE in the afternoon, only 6 mph. The energy is still moderate (784), but the conditions are clean, clean, clean. This is your best window for a smooth, effortless session. It’s not maxing out, but the quality will be there.

Friday the 31st through the weekend sees the swell fading and the wind turning onshore or cross-shore. It’ll be small and messy, not worth paddling out for. There’s a gap of a few days of pretty poor, small surf.

Then we get a late call on Monday the 3rd of August. The wind goes offshore from the E, and we get a solid 6ft SW swell with a 14-second period. The energy is back up (1135), and it’s clean. That Tuesday the 4th slumps back down, so Monday is the one to aim for in that second week.

After that, the forecast gets ugly. From the 5th through the 12th, the wind is a mess – strong cross-shore and onshore, and the swell gets big and unruly. By the 10th and 11th, it’s pumping 10ft to 12ft, but it’s blown out and lumpy. That kind of power with crap wind is more of a kite-surfing mission than a paddle session. Unless you’re a total charger, give it a miss.

The call: If you want the best of it, get on Cunns for Thursday morning the 30th. That light offshore wind and clean 5ft SW swell will be a treat. For the bigger stuff, Wednesday the 29th is your window, but that’s for experts only.

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.
