Grab a coffee and settle in. Rusty here.
Right off the bat, I gotta be straight with you: this is not a classic run for Cunns. We've got a long, painful wait ahead before things get any good. The first week and a half is pretty much a write-off with onshore rubbish, so don't even bother looking at it until we get past the middle of the month.
The first real glimmer of hope shows up on Wednesday, July 15th. That morning we’ll see a clean 5ft SW groundswell with a long 14-second period. The wind will be a light offshore breeze, so expect some proper shape on those waves. That combined energy is in the moderate range, but with those conditions, it’s your best bet for an actual surf. It's an advanced reef, and it's inconsistent, so don't expect a crowd—but when it comes in, it'll be good.
Then there’s another standout window on Monday, July 20th. The morning session looks unreal with glassy conditions, a clean 6ft SW swell and a long 16-second period. The combined energy jumps up nicely, and with the wind totally dead, it'll be like a mirror out there. That afternoon stays clean and cross-off too. This is the one to circle on the calendar if you can hold out.
Other than that, it's mostly cross-onshore, lumpy, or just too small and messy to bother with. A few days in the second week have some size but the wind ruins it. The big spike on July 24th with 6ft and a solid 19-second period looks promising on paper, but with a 25 mph onshore wind, it’s just a washing machine. Not for paddling.
So, to sum it up: tough start, but the 15th and 20th are your true standouts. Get on them while they’re clean.
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.
