The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up at Cunns. It’s a bit of a slow burn, but there’s a real sweet spot in there if you’re patient. This is a reef break, and it’s inconsistent, so you can’t just rock up any day and expect it to be firing.
The week kicks off on Wednesday the 22nd with nothing to write home about—small, cross-shore breeze, and the wave energy is weak (280). It’s a write-off. Thursday the 23rd lifts a little as a solid SW groundswell builds, with 6ft to 7ft waves and a long 14-15 second period, but the wind is still a messy cross-off at 15 mph. The energy is ramping up (1171 to 1768), but it’s still not clean enough to get excited about.
Now, here’s where it gets good. Friday the 24th of July is your standout. Morning brings 6ft of clean SW swell (15 second period) and an offshore wind from the ESE at just 6 mph. This will be glassy and lined up. The combined energy is a solid 1297—moderate to strong. This is a proper expert wave for the experienced crew, but the consistency of the break is rare, so when it’s on, it’s on. The water temp is 61°F, which is pretty average for this time of year. Saturday the 25th still has some fun leftovers at 4ft to 4ft, clean and light winds, but the energy drops off a bit (552 to 453).
Sunday the 26th through Tuesday the 28th is a dead zone. The wind swings onshore, the wave quality drops to poor, and it’s not worth paddling out. There’s a gap of almost three days with no recommendations.
Things try to rally again on Wednesday the 29th with 5ft SW swell and clean cross-off winds, but the scores are marginal. The energy picks back up (1136), but the break is so inconsistent that you’d need to be lucky. Thursday the 30th afternoon has a gentle offshore wind and 4ft swell (444 energy) for a small, clean session. After that, it’s a messy run of onshore wind and building swell through the first week of August. By the 3rd of August, we’re looking at 8ft SW swell with 31 mph winds—that’s big and blown out, more for the kite crew than paddlers. The long period 20 second swell is getting stripped by the wind.
The very tail end on Thursday the 6th of August shows some promise with 4ft SW groundswell, a long 18 second period, and light cross-off winds from the NE. The energy is there (816), and the conditions look good, but it’s a long way off, so keep an eye on that one.
To sum it up: your only real standout is Friday morning the 24th of July at Cunns. Get it while it’s clean. The rest is a waiting game.
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.
