The Lowdown

Right, let’s have a look at what’s on the cards for the next couple of weeks. It’s a bit of a slow start, but there’s some real gold waiting for us if we’re patient.

The only spot in the game here is Cunns, a proper reef break that loves a solid SW swell. The first few days are pretty average, with a bit of cross-breeze and not much going on. Saturday the 25th is a write-off, with only 4ft of swell and a messy cross-shore. Sunday and Monday are even worse, with the wind picking up and the surf dropping off. It’s not looking like a good time to paddle out.

But then, things start to shape up. Tuesday the 28th is where it begins to get interesting. The wind swings to a cross-off from the south, and we’ve got a clean 6ft SW swell with a combined energy of 1269 – that’s a solid amount of power. The water temp is about average for this time of year, nothing out of the ordinary. This is a step in the right direction.

Now, the real standout is Wednesday the 29th. This is the one you’ve been waiting for. The morning sees a 6ft SW swell with a period of 15 seconds, and the combined energy is a meaty 1716. The wind is a gentle cross-off from the southeast, keeping the faces clean. In the afternoon, it gets even better, with the wind turning offshore and the swell sitting at 6ft. This is excellent surf for experienced surfers – the kind of day that makes you forget about the flat spells. The long period means those waves will have real shape and power, and with the reef bottom, it’ll be a proper session. Just be aware that this spot is inconsistent, so when it’s on, it’s on.

Thursday the 30th and Friday the 31st hold some clean, fun waves in the 3ft to 5ft range, with that same SW direction and light winds. It’s good, but not the peak of the week.

Then, we get another absolute beauty on Saturday the 1st of August. The afternoon is a dream: a 3ft SW swell, but the period jumps to an incredible 22 seconds, and the combined energy hits 1706. The wind is a slight offshore from the southeast. This is a very long-period groundswell, and at a reef like Cunns, that’s pure magic. The waves will be long, clean, and have a heap of energy. This is the other standout, and it’s a big one.

The second week gets a bit messy again. Sunday the 2nd has a decent 6ft swell, but the cross-shore wind will put a bit of chop on it. The rest of the week is a mix of onshore winds and average conditions, with a few clean moments trying to break through. There’s a glimmer of hope on Saturday the 8th with a cross-off breeze and a clean 4ft swell, but the energy is lower.

So, to sum it up: the pick of the bunch is hands down Wednesday the 29th, with the 6ft SW swell and clean offshore winds in the afternoon. A close second is Saturday the 1st of August, with that 22-second period groundswell and glassy conditions. Get out there for those two days, and you’ll be stoked. The rest of the time, keep an eye on the forecast, but these are the ones to circle on the calendar.

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.
