The Lowdown
Alright, this is Rusty, and I’m looking at Cunns. This is a deep-water reef break, exposed to the southwest. It's inconsistent, so when it fires, you need to be here. The water temp is about average for this time of year.
Things kick off on Friday, July 24th. We’ve got a solid 6ft SW groundswell with a 15-second period rolling in. The combined energy is strong (1314). That’s a lot of water moving under the surface. Wind is a light cross-offshore from the SE at 6 mph, which will keep it clean. This is solid, heavy surf, definitely for the experienced surfer only. Saturday morning, July 25th, the swell drops to 4ft SW, but the wind goes glassy from the SSW. That’s a rare treat, clean and smooth. The energy drops to moderate (488), but the quality will be high for the crew that can paddle out.
Sunday afternoon, July 26th, picks up a little with a clean cross-offshore breeze and 4ft SW swell. The period is still a decent 12 seconds. It’s a good, mellow option.
Now, the standout window. Tuesday, July 28th, is a write-off with onshore wind, but Wednesday, July 29th, is where it’s at. The morning brings a strong 6ft SW swell at 14 seconds, with very strong energy (1267). The wind is a clean 12 mph offshore from the ESE. That’s juice. This is an expert-level session, but it could be epic. Thursday, July 30th, follows with a solid 5ft SW swell and a light cross-offshore breeze in the morning, going glassy in the afternoon. The energy is still high (953). Very clean conditions.
The first week of August has some size. August 1st shows 7ft SW swell, but it’s cross-shore wind. August 3rd is another standout: Monday morning has a bigger 7ft SW swell, with a clean cross-offshore wind, and Monday afternoon turns into a clean 12 mph offshore wind on a 7ft SW swell. That’s another expert session with strong energy (2203 and 1684). The period is a long 15-16 seconds, so expect long lines and long waits between sets.
Overall, the best on offer is Wednesday, July 29th, with that clean offshore wind on a solid, long-period SW groundswell. August 3rd is a close second, but it’s further out so a little less certain. The rest of the period has waves, but the wind is often a factor. Remember, this break is inconsistent, so it’s not always pumping, but when these windows line up, it’s worth the trip.
Alright, that’s it from me. Get on it.
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.
