Alright, let’s talk about it in feet and miles per hour. Same story, different numbers.
We got one spot to look at: Cunns. This is a reef break, and it’s inconsistent, so you gotta be on your game. Water’s about 61°F, which is pretty normal for around here.
Wednesday the 8th starts off with some decent size – a 6ft SW swell with a long 17-second period. The combined energy is 1710 (moderate to strong). But the wind is a cross-off from the NE at 12 mph, so it’s a little textured. It’s rideable, but not clean.
Thursday the 9th is a nice little window. The morning goes glassy with a light NNW breeze at 3 mph. The swell drops to 4ft at 15 seconds, energy at 606 (moderate), but the surface will be perfect. Small but clean.
Friday the 10th and Saturday the 11th are trash. Onshore wind picks up to 22 mph, turning the 6ft to 8ft swell into a lumpy, choppy mess. Saturday afternoon’s period is a short 7 seconds – that’s pure junk.
Sunday the 12th through Tuesday the 14th has some serious size, with the swell hitting 8ft on Sunday afternoon and energy hitting 2916 (very strong). But the wind is a fresh cross-onshore at 19 to 25 mph. It’s big, powerful, and blown out. Expert-only based on size, but the wind is the enemy.
Now, the main event: Wednesday the 15th. Morning brings a 6ft SW swell with a 15-second period, energy at 1441 (moderate). The wind is a light cross-off from the SE at 6 mph. The report says “excellent for experienced surfers.” This is clean, long-period groundswell wrapping into the reef. Crowds are *sometimes* an issue, so expect a few. Swell direction matches the optimum – it’s all on. This is the one.
Thursday the 16th is a good follow-up: 5ft, 14 seconds, clean conditions.
From Friday the 17th onward, the wind turns sour, blowing out the smaller swells. But then, look at Wednesday the 22nd. The afternoon goes glassy again. We get a 7ft SW swell, period of 15 seconds, with energy at 2018 (strong). The report says “excellent for experienced surfers.” That’s two weeks out, so it’s a hopeful one, but if it comes together, it’ll be another ripper.
Bottom line: the first week has a tiny clean session on the 9th, but the real standout is the 15th. The second week has a promising glassy day on the 22nd. Keep your fingers crossed for that wind. 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.
