Mateys, Rusty here with the outlook for Cunns. We’ve got a solid run of swell on the way, but the wind’s gonna be a bastard for most of it. Let’s break it down.

First up, Friday the 10th of July. We’ve got some small 4ft SW swell rolling in, with a long 15-second period—proper groundswell. The morning’s got a light cross-on NW breeze, not ideal but not terrible, with combined energy at 559, which is moderate. The water’s sitting at 61°, about average for this time of year. It’s only a 1 out of 10 though, so don’t get your hopes up. Afternoon turns onshore and goes to zero.

Saturday the 11th is a write-off. The swell jumps to 7ft, but it’s short period, messy cross-on winds, and combined energy jumps to 455 in the morning and 834 in the afternoon—still moderate, but the conditions are poor. Not worth paddling out.

Sunday the 12th is bigger, with 8ft SW swell and a 12-second period, combined energy hitting 3263—strong stuff. But the wind’s cross-on and choppy, so it’s marginal at best. This is only for experts if you’re desperate, but honestly, don’t bother.

Monday the 13th and Tuesday the 14th stay big—10ft and 8ft—with strong energy (6398 and 2943), but the wind is either onshore or cross-shore. Tuesday afternoon shows some promise with a gentle cross-shore and a 3 out of 10, but it’s still messy.

Now, here’s where it gets good. Wednesday the 15th of July is the standout. The swell drops to a clean 6ft SW with a long 15-second period, combined energy at a moderate 1322. But the wind—ah, the wind! Morning brings a light cross-off ENE breeze, and afternoon goes full offshore from the east. That means clean, groomed waves. It’s excellent for experienced surfers, scoring a 4 out of 10. This is the best on offer, hands down.

After that, it drops off. Thursday the 16th is small again at 4ft with cross winds, scoring 1 out of 10. Friday the 17th and Saturday the 18th are poor—small swell and strong, messy winds. Sunday the 19th sees a pulse of 7ft, then 10ft, but with cross-on winds, it’s no good.

Monday the 20th stays big (10ft) but messy. Then Tuesday the 21st of July brings another highlight. Morning has an 8ft SW swell with a 12-second period, combined energy at 1830—strong. But the wind is light and cross-off from the south, making it clean. Excellent for experienced surfers, scoring a 4 out of 10. Afternoon is a little less with a light cross-shore, still a 3 out of 10.

Wednesday the 22nd is solid too: 7ft SW, 10-second period, combined energy at 934—moderate. Light cross-off winds mean clean surf. Scores a 3 out of 10 for very good conditions.

After that, it fades. Thursday the 23rd drops to 5ft, and from Friday the 24th through Saturday the 25th, it’s all small, messy, and poor.

So, to sum it up: the entire run is plagued by onshore and cross winds, but Wednesday the 15th and Tuesday the 21st are your windows. Both have clean conditions with SW groundswell. Wednesday is smaller and cleaner, Tuesday a bit bigger. Pick your poison, but don’t sleep on that Wednesday morning offshore breeze.

Rusty out.

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.
