The Lowdown
Alright, Rusty here, let’s take a look at what’s coming up for Cunns.
We’ve got a solid run of surf lined up, but it’s a slow start. The first few days are a write-off, so don’t bother paddling out until Wednesday morning. The wait is worth it though.
The first real chance to get wet is from Wednesday, July 29th. The morning kicks off with a clean 8ft SW groundswell (period 16 seconds) and manageable cross-offshore winds. That’s a healthy size—only for experienced surfers at this point. The energy is strong (2896), and the water temp is sitting at 60°F, which is about average for this time of year. The real standout is *Wednesday afternoon*: the swell drops just a touch to 7ft, but the wind goes lighter and cleaner, delivering excellent conditions for experienced surfers. That afternoon session is the pick of the first week.
Thursday, July 30th, keeps the goods rolling with a smaller 5ft to 4ft SW swell, clean and glassy under light offshore breezes. It’s still good, but not as pumping as the day before.
Friday, July 31st, fades quickly. The swell drops to under 3ft, and the wind goes cross-shore, making it choppy and messy. Not worth a paddle.
Then we hit a bit of a lull. Saturday, August 1st, is blown out with strong cross-onshore winds, and Sunday morning is still a bit lumpy. But *Sunday afternoon* (August 2nd) lights up again: a clean 7ft SW groundswell (16 seconds) with light offshore winds. That’s another excellent session for experienced surfers.
Monday, August 3rd, is a gem. Clean 6ft SW swell, light winds, and excellent conditions all day. The energy is strong (1374), and it’s a solid session for anyone who can handle it.
After that, things get messy from Tuesday, August 4th, through to the end of the first week. The swell stays around 4ft to 5ft, but the wind turns cross-shore and fresh, creating lumpy chop. Not worth chasing.
The second week opens with a bit of hope on Wednesday, August 5th, but the 5ft to 5ft SW swell is marred by fresh cross-shore winds. It’s marginal at best. Thursday, August 6th, is flat and poor.
Friday, August 7th, offers a tiny 2ft to 3ft SW swell with a very long period (22 seconds). That’s a classic groundswell, but it’s small and the wind is cross-onshore. Not great.
The real standout for the entire 16-day window is *Tuesday, August 11th, afternoon*. That’s the one to circle. A clean, glassy 7ft swell from the west, with a very long period of 20 seconds, and light offshore winds. The energy is massive (3723), and the conditions are rated excellent for experienced surfers. That’s the best wave of the whole forecast period—pure, powerful, and clean. Just know that with a period that long, it’s going to be better suited to the point and reef at Cunns than a beach break. It’s a promise, but it’s two weeks out, so keep an eye on it.
Stay safe, don’t get greedy on the big days, and I’ll see you in the lineup.
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.
