Right then, let’s have a look at what’s on the cards for Cunns. Over the next couple of weeks, we’ve got some solid, long-period SW groundswell rolling in, but the wind and tide windows will make or break it. There are patches of absolute gold if you time it right, especially for the experienced crew. This is a reef break that’s inconsistent, so don’t expect it to be pumping every day – you gotta pick your moments.
The water temp is hangin’ around about average for this time of year, so nothin’ wild there, just your standard chilly winter dip.
Alright, let’s get into it. This week starts off a bit average. Sunday the 5th has some decent energy – we’re talkin’ 6ft to 6ft of SW swell with a juicy 16 to 17 second period, and the combined energy is strong at 2191. The wind’s a cross-off from the ENE though, keepin’ it clean but not perfect. Still, it’s rideable.
Monday the 6th drops off a fair bit – down around 4ft to 3ft. The afternoon shapes up better with an offshore E wind, makin’ it clean for the smaller waves. Tuesday the 7th is a similar story, small but clean in the arvo with a light SE offshore and a bit more period. The real spark comes Wednesday the 8th: a solid 6ft SW swell, 17 second period, big combined energy of 1710, and a light NE cross-off in the morning. That’s the standout of the first week – good wave shape, loads of power, and clean conditions. It’s marked for experienced surfers, and rightly so.
After that, things get messy. Thursday and Friday (9th and 10th) are a write-off with onshore or cross-onshore winds, lumpy and choppy. Saturday the 11th is blown out completely with 19-22 mph winds – avoid it. Sunday the 12th has a solid 7ft SW swell but the wind is on it again, makin’ it a frustrating one.
Now, rollin’ into the second week, there’s a real big one brewing for Sunday the 19th. We’re lookin’ at a 8ft SW swell, 17 second period, and the combined energy is massive at 6647 – that’s very strong. With a light SSE cross-off wind and clean conditions, this is the absolute standout of the whole forecast. It’s for expert surfers only though – way too powerful for anyone else. This one is a true dawn-patrol mission.
Monday the 20th still has a good 7ft SW swell and clean cross-off wind, but it’s a step down from the Sunday. The rest of the days around that, like the 15th, 16th, and 18th, have some ok waves in the 4ft to 7ft range, but the wind is never quite perfect, giving you that lumpy or cross-chop texture.
Bottom line: The first week’s best bet is Wednesday morning the 8th for a solid, clean session. The standout of the whole period, though, is Sunday morning the 19th – big, powerful, and clean. Get on it if you’ve got the skill. Just remember, this spot is inconsistent, so don’t bank on it every day.

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.
