Table - best surf conditions forecast for Cunns over the next 16 days.
Alright, Rusty here, givin’ you the lowdown on Cunns. The first few days are a total bust—blown out, choppy, and not worth paddling out for. That’s a solid 4-day gap of dud conditions before we see a glimmer of hope.
The one and only real standout is Wednesday, July 15th. The wind turns glassy, light offshore from the ESE, and the wave faces clean right up. We’re lookin’ at a solid 6ft of SW groundswell with a long, powerful 15 to 16-second period. The wave energy is strong (1474), and the water temps are a little below average at 61°F, so a wetsuit is the call. Since Cunns is a reef break, that long-period swell will wrap in just right, though it’s an inconsistent spot, so you gotta be patient. Crowds are listed as “sometimes,” so you might get a few heads, but nothing nuts.
The morning of the 15th is the absolute best of the whole forecast. Clean lines, good size, and that offshore breeze making it silky. The swell is 6ft, so it’s for the experienced crew only. The afternoon stays excellent with a solid 5ft of clean swell.
After that, the magic fades fast. The 16th is still clean but smaller, and from the 17th onward, it’s a slow slide into choppy, onshore junk. The last week is just weak, wind-affected slop barely chest-high.
So, if you’re smart, you’ll be on it Wednesday morning, July 15th. That’s the only real window. Everything else is a washout.
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.
