Table - best surf conditions forecast for Cunns over the next 16 days.


Alright, let’s get into it. We’ve only got one spot to look at for the next couple of weeks, and it’s a real specific one: Cunns, a reef break that’s all about the SW swell. This isn’t a beach break you can just roll up to, it’s a proper reef setup for advanced surfers. And it’s inconsistent, so you have to pick your moments.

The first real chance to get in the water is on the morning of July 15th, Wednesday. That’s when things finally start to line up. The swell is a clean 5 ft out of the SW, with a long 15-second period. That’s proper groundswell, but on a reef, it’ll hold up nicely. The wind is light and offshore from the ENE, so the surface will be clean. The combined energy is 1108, which is solid, moderate energy. It’s not huge, but it’s well-shaped. The afternoon is even better – the wind swings to a light offshore from the east, keeping it glassy. This is the standout window. A real 4 out of 10 kind of day, but for this break, with these conditions, it’s the best we’ll see.

Now, before that, the 13th and 14th are a write-off. Monday morning on the 13th has an 8 ft SW swell with a 16-second period, but it’s onshore wind and choppy, with combined energy over 3000, so it’s just a messy, powerful mess. Tuesday the 14th is a bit smaller but still cross-shore and marginal.

After Wednesday the 15th, it goes downhill again. Thursday the 16th drops to 4 ft and 5 ft, but the wind is cross-shore and moderate, just not clean. By Friday the 17th, it’s poor and windy, and the swell fades fast. The weekend of the 18th and 19th is tiny – 2 ft to 3 ft – and onshore, so forget it. There’s a little bump back up to 5 ft on the 20th, but the wind is cross-shore again, so it’s still marginal.

Then we get a big pause. The 21st through the 23rd are all blown out with strong winds and poor surf. The 22nd has an 8 ft swell, but it’s onshore and messy, with a shorter 11-second period. That’s more of a windy mess than a surfable wave.

The real potential second chance comes on the 24th of July, Friday. The swell picks up to 6 ft in the morning and 7 ft in the afternoon, out of the WSW, with a very long 18-19 second period. The combined energy is impressive – 2669 and 4800 – that’s strong to very strong. But the wind is cross-onshore, and the report says “fairly choppy,” so it’s marginal. For an advanced crew on a reef, you might get some big, clean lines between the chop, but it’s not the clean, glassy day we had on the 15th.

The 25th and 26th keep the size around 8 ft to 8 ft, but the wind is cross-shore or onshore, so it’s choppy. The 27th and 28th show some hope with the wind turning cross-offshore and clean, but the swell drops to 7 ft and then 5 ft, and the energy is moderate. It’s clean, but the size is fading.

Bottom line: The best on offer is Wednesday the 15th of July. That’s the one. Clean, offshore, 5 ft SW groundswell, on a reef. It’s the standout. The bigger swells later in the run are too chopped up to be worth the struggle. If you’re an expert, you might get a few on the 24th, but it’s a gamble. For everyone else, it’s a lot of waiting for not much.

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.
