The Lowdown

Right, gather 'round, grab a coffee. Rusty here. Looks like we've got a bit of a mixed bag on the cards for the next couple of weeks, with a quiet start and a few windows of real quality. Let's get straight into it.

The first real surf worth paddling out for is on Friday morning, the 24th of July. We've got a solid 6 ft swell from the SW, with a period of 15 seconds – that's proper groundswell, plenty of energy. And the wind is light offshore from the ESE. That's a magic combination. The break is Cunns, a reef setup, and with that long period, it'll be grooming the reef nicely. The combined energy is sitting at 1436, which is strong. The water temp is about average for this time of year, so no major surprises there. This is easily the standout; it's going to be clean, lined up, and powerful. If you're an experienced surfer, this is your Friday.

The good conditions hang around for the afternoon. Still around 6 ft, period holding at 15 seconds, combined energy at 1212. The wind switches to a clean cross-offshore from the SSE. It's still excellent, but that morning window is the pick.

Saturday morning, the 25th, drops right off. The swell is only 4 ft, the period has dropped to 13 seconds, and the wind goes light and cross-shore. It's just not the same quality. The condition drops right away for a few days after that, nothing worth writing home about.

Now, if you're looking ahead, there's another promising window. The morning of Wednesday, the 29th of July, looks good. We've got a 5 ft SW swell, 14 second period, and a clean offshore wind from the SE. Combined energy is a solid 1050. It's a notch down from the Friday, but still a very good session for the experienced crowd. The afternoon gets a bit more cross-offshore, so the morning is the go.

After that, the conditions start to get messy again. There's a gap from the 31st of July right through to the 6th of August where the wind is just too strong and onshore to make anything of the 3 ft to 5 ft swell that's showing. It's mostly poor conditions, lots of chop and lumpy seas. The swell is there, but the wind is blowing it out. Honestly, for the first week of August, it's looking more like a kitesurfing setup than a clean paddle surf, especially with those strong cross-onshore winds.

So, the short version: Lock in Friday the 24th. That's your best bet. Wednesday the 29th is a solid backup. The rest of the time, keep your eyes on the forecast and hope the wind plays ball.

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.
