Table - best surf conditions forecast for Cunns over the next 16 days.
Alright folks, Rusty here. Let's have a look at what we've got coming down the pike for Cunns. It’s a reef setup that likes swell from the southwest, and for an advanced crew. We’re in for a bit of a wait, but when the ocean turns on, it could be a special one if you’re ready for it.
The water temp's sittin' at 60°, which is bang on average for this time of year, so no surprises when you hit the water.
Right now, and for the next few days, it's a no-go. We've got a lumpy, cross-onshore mess with a strong breeze blowing Friday the 11th and Saturday the 12th, making the ocean look like a washing machine. The swell's got some moderate energy (407 to 1247), but it's all wind-slapped and ugly.
It starts to change up a bit Monday the 13th. The swell jacks up a bit, but the wind is still a problem—that's a strong wave energy reading (3039 and 8310) and period hitting 16 seconds, but the cross-onshore wind is holding it all together in a choppy way. Not for surfing.
Finally, we get our window. Tuesday the 14th. It's not perfect, but the wind drops to a light breeze. The swell is a solid 7ft to 7ft from the southwest, with a very long 16-second period. That's a groundswell with a heap of energy in the water (2543 and 2212). It's still a touch cross-onshore in the morning and cross-shore in the afternoon, so you'll be dealing with some slight wind ripples. This is "marginal" but for the more experienced crew, this is where you start getting a little excited. This is the closest we get to a standout this week for the bold.
Wednesday the 15th is an absolute ripper. This is your best bet. The swell drops a touch to 5ft-6ft from the SW, still with a long 14-second period, but the wind goes light and cross-offshore from the ENE and NE. That’s clean. Glassy. The wave energy is solid (1187 and 998). This is the morning to have your board waxed and ready. The swell at this size, with this wind, and this period, is going to produce some lined-up, well-shaped waves on that reef. It’ll be clean and set up proper. A real standout for the experienced surfer.
After that, Thursday the 16th through next week it drops off into the small stuff and the wind turns messy again. Thursday and Friday the 16th and 17th we’re down to 4ft to 4ft, cross-shore with moderate winds, just marginal. The weekend of the 19th to 20th sees a bit of a bump in size (6ft to 7ft) but a strong cross-onshore kills it. Then the last week of the month (the 21st through the 26th) looks poor with onshore winds and small, weak swell. A few days there are some rain showers too.
So to sum it up: you sit through a grim, blown-out start. Don't bother paddling out until Wednesday the 15th. That’s the day. No crowds listed for that one, so it might be a bit of a local secret session if you're keen. The Tuesday beforehand is worth a look for the brave lads, but the Wednesday morning is the clean, lined-up gem in this 16-day forecast.
Stay stoked,
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.
