The Lowdown
Alright, Rusty here. Let's have a look at what's on offer over the next couple of weeks for Cunns.
Right now, things are kicking off on Tuesday, 8th September, with some proper groundswell from the SW at 5 ft, and a period of 17 seconds. That’s a long period groundswell, and while it packs a punch with a combined wave energy of 1388, a reef setup like Cunns should handle it well. The morning's offshore wind from the east is a beauty, keeping it clean, but this is an advanced reef break and it's inconsistent, so you need to know what you’re doing. Afternoon sees the wind swing a bit, but it stays clean.
Wednesday the 9th is a bit of a write-off. The swell jumps a bit, but that wind cranks up to a solid 25 mph from the ESE in the morning. It's offshore, but way too strong, making it a fight to get out. The afternoon gets messy too.
Thursday the 10th and Friday the 11th are okay, but nothing special. The swell is dropping through Friday, though by Friday afternoon it gets clean with a gentle breeze and a 4 ft SW swell (15s period). You’ll get some fun ones, but it’s not the standout window.
The weekend from Saturday the 12th through to Monday the 14th is a write-off. Onshore winds and lumpy, messy conditions. A good time to do something else.
Now, here’s the standout. Look at Wednesday the 16th and Thursday the 17th. Wednesday morning serves up a 5 ft SW swell at 15 seconds, and the wind is from the ESE at only 3 mph – nearly glassy. Combined wave energy is a solid 1232, and the surf report calls it excellent for experienced surfers. That afternoon is similar, with a 5 ft swell and the same glassy conditions. Thursday morning the 17th is your other gem: the wind goes totally glassy, with a 4 ft SW swell at 14 seconds. It’s a bit smaller, but with no wind, it’ll be pristine. Cunns is an inconsistent reef, so when it lines up like this, you’ve got to make the call.
After that, things get blown out again from Friday the 18th through the weekend, with strong onshore winds and messy surf. The following week shows some more promising signs around Tuesday the 22nd with a 5 ft SW swell and clean cross-off wind, but by that point we're getting deep into the forecast.
So, in short: the absolute best is Wednesday the 16th and Thursday the 17th. Light wind, solid SW groundswell, and that reef will be firing for those who can handle it.
Later, 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.
