The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Cunns over the next couple of weeks.

Well, it's a bit of a slow start, I'm not gonna lie. The first few days are a write-off, with choppy, onshore winds and no real quality. We're looking at a gap of a few days before things start to get interesting.

The real standout of this whole forecast is the period from Thursday the 24th through to Friday the 25th. That's the window to lock in. Thursday morning sees a solid 7ft groundswell from the SW with a period of 14 seconds, and the wind is cross-off, keeping things clean. The combined energy is strong at 1832, so there's plenty of grunt in the water. It's a bit big for the beginners, but for the experienced crew, it's game on. Thursday afternoon stays solid with 7ft SW swell (1879 energy) and a clean cross-off breeze.

But Friday the 24th is the pick of the lot. The morning session is looking prime: 6ft of SW groundswell with a 15-second period, and the wind is offshore. That's glassy, clean perfection. The combined energy is a very strong 1212. It's still solid enough that only the more experienced surfers should be paddling out, but the quality of the wave is going to be excellent. Friday afternoon holds up nicely too, with 5ft SW swell and a light cross-off breeze.

Cunns is a reef break that's inconsistent, so when it does line up, you've got to be on it. It's exposed to the SW, which is exactly what we're getting. Crowds are possible here, so be prepared for company if you're heading out for that Friday morning glass-off.

The days leading up to that are marginal. Tuesday afternoon the 21st turns glassy with 4ft SW swell, but it's a bit small. Wednesday the 22nd has some size but the wind is messy.

After the Friday high, it fades out. Saturday the 25th and Sunday the 26th see smaller, weakening swell and the wind swings back onshore, killing the quality. Then we get a massive spike in size on Monday the 27th and Tuesday the 28th, with 10ft and 7ft SW swells, but the wind is howling onshore, making it a total mess. It's worth saying that setup looks more interesting for kite surfing than paddle surfing. The rest of the forecast into the first week of August is poor, with small, wind-affected surf and no real quality on offer.

So, to sum it up: the window is tight. The best on offer is Friday morning, the 24th of July. Get out there if you can.

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.
