The Lowdown
Alright, let's talk about Cunns. This is a reef break that needs a good SW groundswell to wake up, and it ain't a consistent spot, so you gotta be keen. The water's sitting at 60°F, which is right about normal for this time of year.
The first real action is on Friday, July 24th. It's not the biggest standout, but we've got a 1.7m (6ft) SW swell with a very long 15-second period, pushing a massive 1314 energy into the reef. The wind is light cross-off from the SE, so the waves will be clean. This is expert territory at that size, and the crowd factor is "sometimes," so you might have to share. The south-west swell is exactly what this spot wants.
Friday afternoon stays similar, still 1.7m (6ft) and clean, with the energy dropping a bit to 1212. Still a solid session for the experienced.
The weekend is a total bust. Saturday, July 25th drops to 1.2m (4ft), messy cross-winds, and the scores are poor. Sunday, July 26th is even worse with onshore wind. Monday, July 27th is a no-go – 35 km/h (22 mph) winds. Don't bother.
Now, the first true gem is Wednesday, July 29th. The morning shows a 2.1m (7ft) SW swell, 15-second period, and a massive 2048 energy. The wind is offshore from the SE at 20 km/h (12 mph), so expect clean, powerful lines. This is proper expert-only – over 2.5m (8ft) is for the hardcore, and 2.1m (7ft) is pushing it for anyone not very comfortable. The afternoon stays clean with 2.0m (7ft).
Thursday, July 30th is still very good, with a 1.4m (5ft) to 1.3m (4ft) SW swell, clean cross-off winds, and moderate energy. A great option for a more relaxed session.
The next big standout is Monday, August 3rd. This is a long-range call, so keep an eye on it, but it looks promising. A 2.3m (8ft) SW groundswell with an 18-second period and a massive 3302 energy. The wind is light and cross-off from the NE, so it'll be glassy clean. Again, big and powerful, experts only. Tuesday, August 4th sees the swell drop to 1.8m (6ft), but the wind turns cross-on, so it's choppier.
Wednesday, August 5th is a real treat. The morning is glassy with a 1.5m (5ft) SW swell, 14-second period, and 899 energy. The wind is literally glass, so you'll get perfect, clean waves. The size is big enough for a good time but not so big that it's only for the madmen. The period is long, so it'll be a groundswell with proper shape.
After that, the surf fades badly from Thursday, August 6th onwards, with onshore winds and dropping energy into the second week. The 8th of August is a total dud.
So, for the experts, the clear standout is the morning of Wednesday, July 29th – big, clean, and powerful. For a more manageable but still excellent session, the morning of Wednesday, August 5th with glassy conditions is your best bet. The long-range Monday, August 3rd is the biggest wave of the forecast, but it's a wait-and-see.

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.

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.
