The Lowdown

Alright, folks, Rusty here.

Well, it’s a bit of a slow burn for the next week and a half, but there are a couple of windows where it’s worth paddling out. The main event looks to be a solid, long-period SW groundswell rolling in from Tuesday the 14th, but the cleanest conditions for it are tight. The water temp is sitting at 60°F, which is about bang on average for this time of year.

The real standout, and the one I’d be circling on the calendar, is Tuesday afternoon the 14th at Cunns. That’s a right reef set-up, exposed to the SW. We’ve got a solid 7ft SW swell at a long 16 seconds, which is proper groundswell. The combined energy is pumping at 2325, so it’s got some serious push. The wind is a clean offshore S breeze at 9 mph, which means the face will be smooth. This is advanced territory, and it’s an inconsistent spot, so you’ll need patience, but when a set comes through, it’ll be worth the wait. It can get busy here sometimes, so expect a few others with the same idea.

Wednesday the 15th is also a solid runner, with a bit less size. The morning session is the call. You’ve got a 6ft SW swell, still a long 15-second period, and a light offshore ENE breeze at 6 mph. The energy is high at 1204, and the conditions are clean. The afternoon holds up too, with 5ft and the same 15-second period, but the wind picks up a notch to 9 mph. Still a good day to be in the water.

After that, things get a bit grotty. From Thursday the 16th through the weekend, the wind swings onshore and the swell drops. A lot of moderate cross-shore chop and poor conditions. The swell stays small with cross-shore winds, so it’s not really worth the effort.

There’s a brief flicker of hope on Wednesday afternoon the 22nd. The swell is only 4ft from the WSW, but the wind drops to nothing and it goes glassy. The energy is moderate at 694. It’s a small window, but if you’re desperate for a couple of clean ones, that’s your moment.

The end of the month looks rough. Strong winds, rain, and blown-out conditions from the 26th onward. The swell is small and the wind is howling, so it’s more of a kite-surfing setup than a paddle session.

The long-range look at Saturday the 25th has a tiny bit of hope: a 3ft SW swell with a light offshore breeze in the morning, then glassy conditions in the afternoon. It’s small, but clean. Keep an eye on that one as it gets closer.

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.
