The Lowdown
Alright, listen up. The next couple of days are looking pretty solid for the experienced crew around here. We’ve got a good, solid groundswell from the southwest rolling in, and if you’re on it, it’s going to be clean.
The main event is at Cunns. This is an advanced reef break, and it’s inconsistent, so you’ve got to be patient and know what you’re doing. The water temp is sitting at 60°F, which is pretty much normal for this time of year, so a spring suit will do.
Tuesday 14th July afternoon is where it’s at. You’re looking at a solid 7ft SW swell with a very long period of 16 seconds, packing some serious power – the combined swell energy is up at (2389), which is strong. The wind is a light 6 mph from the south, holding it in a cross-off position, which will keep it glassy and clean. This is the standout session. It has got that deep, powerful feel, and with a light breeze like that, the faces will be smooth.
Wednesday 15th keeps the quality up. The morning starts with a 6ft SW swell (1204 energy), 15-second period, and a light 9 mph ENE breeze keeping it cross-off and clean. The afternoon drops a little to 5ft but still holds that lovely 15-second period (1011 energy) and clean conditions. Both sessions are excellent for experienced surfers.
Now, Thursday 16th sees the quality drop. The swell is still 5ft but the wind swings to a moderate 13 mph from the NNE, putting it in a cross position with a chop on it. The forecast turns marginal from here.
From Friday 17th through to Monday 20th, it’s a write-off. The swell drops off, the wind gets messy and onshore, and we’re looking at poor to marginal conditions. There’s about a 5-day gap here with nothing worth paddling for.
Tuesday 21st July morning brings a flicker of hope. The swell is a modest 4ft, but the wind drops to a whisper at 3 mph from the SSE, giving us a clean cross-off. The combined energy is weak though, at (433), but it’s rideable.
Wednesday 22nd is a mess again with onshore winds and lumpy conditions.
But hold onto your leash, because Thursday 23rd July morning looks like a second real standout. The swell bumps back up to a solid 6ft from the SW (1452 energy) with a 15-second period. The wind is a light 9 mph from the south, holding it in a cross-off position. It’s clean and powerful. This is excellent for experts.
Friday 24th and Saturday 25th continue the good run. Friday sees 5ft SW swell with clean 9 mph winds from the east and southeast. Saturday 25th afternoon is a beauty – 4ft SW swell with a 14-second period, and the wind goes glassy at 3 mph from the southeast. That’s a truly clean, smooth afternoon session. The combined energy is a moderate (790).
After that, from Sunday 26th right through to the end of the period on Wednesday 29th, the window shuts again. The wind cranks onshore from the north and west, and the swell drops away. It’s poor, lumpy, and not worth the effort.
So, to sum it up: your two absolute best bets are Tuesday 14th July afternoon and Thursday 23rd July morning. Get on them while the conditions line up. The long period swells at Cunns will be running fast and deep, so keep your head up and pick your waves.

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.
