The Lowdown

Alright, Rusty here. Let’s cut through the noise and talk about what’s on offer at Cunns for the next couple of weeks.

This is a classic reef setup that really needs the wind and swell to line up. It’s exposed to a SW swell, and for the most part, the wind is going to be a battle. The first few days are pretty much a write-off, with strong cross-onshore winds and messy, lumpy conditions. Not worth paddling out for.

Things start to turn around on Wednesday, 29 July. The morning sees a 8ft SW swell with a 16-second period, and the wind swings to a cross-offshore. The combined energy hits 2868 (strong), and the conditions are described as clean. This is a solid, powerful groundswell, but being a reef break, that long period will really focus the energy. The afternoon holds similar quality with a 7ft swell. This is expert territory at that size, but for those who can handle it, it’s the best on offer in the first week.

Thursday, 30 July, is a real standout. The swell drops to 5ft in the morning but the wind goes light, then in the afternoon we get a clean 4ft SW swell with a 6 mph offshore breeze from the SE. The combined energy is moderate (594), but the conditions are described as very good surf. This is the day to call in sick. Clean, offshore, and a manageable size for a confident intermediate.

After that, the wind gets messy again with a lot of cross and cross-on conditions, and the swell jumps around. The long-range stuff from the 5th and 6th of August shows some clean windows with moderate cross-offshore breezes and 3ft to 4ft SW swell, but the energy is weak and the consistency is nothing to write home about. The second week is a mixed bag, with some clean mornings but nothing that screams “must surf.”

The pick of the entire period is Thursday, 30 July afternoon. It’s clean, offshore, with a solid 4ft SW groundswell. That’s the one.

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.
