The Lowdown

G’day, Rusty here. Let’s cut through the noise and look at what we’ve got on the cards for Cunns over the next couple of weeks. It’s a mixed bag, so I’ll walk you through it day by day.

The opening stretch is a bit of a write-off, to be honest. Saturday and Sunday are marred by lumpy, cross-onshore winds and messy conditions. There’s swell, but it’s not doing us any favors with the chop. You’d be fighting it all session. We’re looking at a couple of days with nothing worthwhile to paddle into.

Things start to settle down early in the week. Monday the 14th is where it turns on. The wind goes light and glassy in the morning, and while the swell is small at 3ft from the southwest with an 11-second period, it’s clean. It’s a knee-to-waist high kind of day, but the lack of wind makes it feel way better than the size suggests. The energy is weak though, only 380, so it’s more about a fun cruise than a proper hit.

The next couple of days bring a touch more size and better period. Tuesday the 15th sees the swell pick up to 5ft from the SW, and the morning gets a fresh offshore SE wind. This is where it starts to get interesting. The energy is kicking into a moderate range at 962. Wednesday the 16th is even better – the swell pushes to 5ft-5.5ft, the period is a solid 15 seconds, and we’ve got clean offshore winds all day. Energy jumps to over 1100 and then 1306 in the arvo. This is your first real standout of the stretch. Clean, meaningful lines at Cunns (North Coast). It’s a proper reef break, so this long-period swell is right at home.

The swell backs off a bit for Thursday the 17th, dropping back to around 3ft-3.5ft, but it’s still clean with a nice 14-second period. A better bet is the Friday the 18th, but the wind swings north and kills it. Small and lumpy. Saturday the 19th is a write-off with strong onshore winds and the swell dropping away.

Sunday the 20th sees a cross-off wind and the swell starts to rebuild in the afternoon, jumping from 2ft to 5ft from the S/SW. It’s a bit peaky, but the wind is keeping it clean. Monday the 21st has more size at 5.5ft but a strong SE breeze makes it a grind. The energy is building though, hitting 1436 in the afternoon.

Now, here’s where I get excited. The standout of the entire outlook is Tuesday the 22nd. We’ve got a decent groundswell at 6.5ft-7ft from the SW, with a 16-second period. The morning has a fresh offshore ESE wind, and the energy is into the low 2000s. The afternoon cleans up even more with a moderate offshore breeze, and it’s marked as excellent for experienced surfers. This is the day to clear your schedule. This is a proper, powerful, clean swell hitting the reef. That’s your biggest and best.

The swell hangs in there for Wednesday the 23rd at 4ft from the SW, but the wind goes a bit onshore in the arvo. Thursday the 24th is interesting. The swell is 4ft in the morning, but the afternoon brings a long-period SW groundswell at a huge 21 seconds, and the energy jumps to 3269. It’s cross-shore and a bit lumpy, but the raw power is there. The period is very long, so it might be a bit straight at times, but the reef should handle it.

But the second real standout, and probably the cleanest big day is Friday the 25th. The swell is up to 6.5ft-7.5ft from the SW with an 18-second period. The wind is light and cross-off from the SSE, and it’s rated as excellent for experienced surfers. The energy is massive – 3289 in the morning. This is another one for the books. Powerful, clean, and a solid size. It’s a big, heavy swell for a reef, so it's not a day for the faint of heart.

The weekend goes a bit sideways again. Saturday the 26th gets messy and blown out. Sunday the 27th has a lot of size – 8ft from the SW – but the wind is cross-onshore and it’s choppy. There’s huge energy (3084 and then 4735 in the arvo), but it’s going to be a battle. For experienced surfers only, and even then, it might be more of a survival session than a fun one. The water temp is around 59.9°, which is pretty normal for this time of year, so you won’t need the thickest suit, but don’t be fooled into going

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.
