The Lowdown

Alright, mates, Rusty here. Let's have a proper look at what the ocean's got cookin' for us at Cunns. This is a spot that demands respect, and this forecast is no different.

The overall picture is a slow burner. We've got a nice, clean start to the period, but there’s a gnarly stretch of onshore, messy surf and building swell in the middle that will have us all shaking our heads. The best action is going to be at the very beginning and then again later in the run, if the long-range models hold true.

Right out of the gate, Monday morning is looking magic. We're talking about a clean 6ft of SW groundswell with a long 14-second period. The wind is glassy, almost nothing out of the SSE. Water temp is sitting at 60°F, which is about normal for this time of year, so it's not a shock to the system. Combined energy is strong at 1273, and it'll be an excellent morning for experienced surfers. If you can get out there, this is the pick of the first few days.

Monday afternoon stays clean with a 5ft SW swell and a light cross-off wind, still looking fun.

Tuesday drops off a bit. The morning has a 4ft SW swell, but a moderate NE cross-off wind will have it a bit lumpy. The afternoon goes glassy again but with less size, only about 3ft. It's going to be small, but still clean.

Wednesday is a bit of a write-off. The wind goes onshore and cross with a 25 km/h breeze from the NNE. The surf is small and choppy, just not worth the paddle out.

We get a sweet little window on Thursday morning. The wind goes offshore from the SE, and we get a clean 4ft SW swell, making for some very good conditions. Thursday afternoon gets a little more size, up to 4ft with a gentle cross-off, but the quality drops to marginal.

Then the wave energy starts to climb, but so does the wind. Friday sees the swell jump to 5ft, but a fresh 30 km/h cross-shore from the north chops it all up. It's a mess.

Saturday is poor. We've got light rain and a strong onshore wind blowing into a building 7ft swell, not what we want to see. Sunday is worse, with a full-on 10ft of SW swell and strong cross-onshore winds. This is a big, stormy mess.

The start of next week, Monday the 10th, is for the kitesurfers, not for us paddle surfers. The swell is huge, hitting 12ft, with a strong onshore wind. It’s a powerful, ugly beast. Don't even think about it.

The ocean starts to settle down by Tuesday the 11th. The swell is still solid at 8ft, but the wind is now cross-shore. It's still lumpy, but it's cleaning up a bit. The afternoon actually looks more promising, with the energy jumping up to 6647, which is strong. It's still a demanding session.

Wednesday the 12th brings more energy and more size. The swell is a solid 10ft from the SW, but the wind is still cross to cross-on, leaving it fairly choppy. This is still only for the very experienced, and even then it will be a battle.

Now, keep your eyes on the prize, because Thursday the 13th starts to turn things around. The morning shows a 8ft SW swell with a light cross-off breeze from the south, and the report calls it excellent for experienced surfers. The energy is strong at 2507, and it looks like we’re finally getting some quality back.

But the real standout of this whole period is Friday the 14th. The guidance is pointing to something special. You’ve got an 8ft SW swell with a 19-second period. That is a serious, long-period groundswell. The morning wind is a moderate offshore from the ESE, which should groom these waves into perfection. It's going to be big, powerful, and lined up. This is a session for experts only, but it should be one to remember. Mark it in your calendar.

Saturday the 15th sees the swell ease off to 4ft, still with clean conditions. Sunday the 16th brings another bump in size, up to 7ft, with a gentle offshore wind and clean conditions, looking like another excellent morning. The afternoon jumps to a solid 10ft, so the energy will be strong.

The final days of the run, Monday the 17th, still look fun with clean 6ft to 7ft surf and light winds.

So here’s the deal. For a guaranteed session, get out this Monday morning. But for the one that could be truly epic, keep your fingers crossed for the 14th. That Friday has the size, the period, and the offshore wind to be something special. Just remember, Cunns is a reef break and can be inconsistent, so bring your patience. It’s all there, just treat it with respect.

Stay salty,
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.
