The Lowdown
Righto, let’s look at what’s coming up for our patch over the next couple of weeks. We’ve only got one spot on the radar, and that’s Cunns. It’s a tricky reef set-up, proper advanced territory, and it doesn’t break all that often—so when it does, it’s worth paying attention to. Water temp is sitting at about 60°F, which is pretty much what we’d expect for this time of year. Nothing weird going on there.
The first week is a mixed bag. We kick off Sunday the 26th with a small 4ft southwest groundswell, period a solid 12 seconds. It’s clean enough but the wind is a light cross-onshore, so you’re looking at a bumpy surface and only marginal conditions. Not worth paddling out for.
Monday the 27th turns ugly. Swell drops to 2ft and the wind howls from the northwest at 35 km/h—just a messy, lumpy day. Not surfable.
Things start to build again on Tuesday the 28th. Swell jumps to 6ft from the southwest, period 14 seconds, and wind turns cross-shore. There’s moderate wave energy (1290) but it’s still got a cross-chop on it. It’s better than Monday, but still marginal.
Wednesday the 29th is where we see the first real hope. Swell hits 8ft (southwest, 16-second period) with a cross-offshore breeze from the SSE at 20 km/h. That’s clean, and the energy is strong (2823). This is only for experienced surfers, though—too big for anyone else. It’s the best session in the first week, no question.
Thursday the 30th is a nice little follow-up. Swell drops to 5ft but the wind turns light offshore from the ENE, glassy clean. Energy is moderate (746). Expect very good surf, but it won’t have the power of Wednesday.
Friday the 31st and Saturday the 1st of August are write-offs—cross-shore winds and small, weak swell. Then Sunday the 2nd shows a moderate 6ft southwest swell, but it’s cross-shore again and chop ruins it.
Now for the real standout. Monday the 3rd of August is the pick of the whole forecast. Swell holds at 7ft from the southwest, period 14 seconds, with a light cross-offshore breeze from the ENE at 15 km/h. Clean lines, strong energy (1766), and conditions are excellent for experienced surfers. This is the day to keep free.
Tuesday the 4th is also worth a look if you miss Monday. Swell drops to 5ft but the period stretches out to 19 seconds—very long groundswell. That means beautifully shaped waves, long gaps between sets. Wind is near glassy, cross-offshore. Energy is strong at 1549. This is a reef, so that long period will work in its favour, not against it.
After that, things turn messy again from Wednesday the 5th through the weekend. Wind picks up, swell gets lumpy. There’s a glimmer on Friday the 7th with 6ft southwest swell and light offshore wind from the SE—clean and powerful (1568). That’s another good day for the experienced crew.
By Sunday the 9th it’s all blown out again.
So to wrap it: if you’re an advanced surfer and can handle a reef, Wednesday the 29th of July, Monday the 3rd of August, and Tuesday the 4th of August are your windows. The Monday is the absolute standout—big, clean, powerful. Crowds at Cunns can turn up sometimes, but with this reputation, you might have it to yourself.

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.
