Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let's break down what Cunns has in store for us. It's a classic reef break, takes that SW swell, but it's an inconsistent spot – you've gotta pick your moments, but the rewards are there.
Water temp's sitting at 61°F, which is about 1°F cooler than the norm for this time of year. Just a bit of a chill.
Monday is a no-go. There's a 4ft SW swell with a 14-second period, but the NE wind is a messy cross-off, and they're calling it marginal. The combined energy is moderate (536), but it's flat.
Tuesday is where we start. The swell holds around 4ft from the SW, but the period stretches to 15-16 seconds, adding some real grunt. The wind Tuesday arvo turns into a clean offshore from the E, and the energy climbs to 635. That's the window – a long period groundswell with a clean face.
Now, Wednesday the 8th of July is the big one. The swell jumps to 6ft from the SW with a 17-second period, and the energy is strong at 1710. The wind is a light cross-off, keeping it clean. This is the standout session for experienced surfers. A 6ft face at a reef with that much period is proper, powerful stuff.
Thursday the 9th is a beauty too, especially the afternoon. The swell is back to 4ft, but the wind goes dead calm and glassy (5 km/h from the E). The energy is 783, so there's still plenty of water moving, but the surface will be perfect.
Then it gets ugly. Friday and Saturday are blown out by onshore winds. By Saturday the 11th, you've got an 8ft swell with a short 6-second period, but it's raining and the wind is strong. Forget it.
From Sunday the 12th through Tuesday the 15th, there's a massive pulse – 10ft swell from the SW with 14-second periods and the energy hitting a whopping 5651 on Monday morning. That's huge. But the cross-onshore wind makes it a lumpy, choppy mess for surfing. If you're a kite surfer, that big, wind-churned ocean is your playground.
Wednesday the 15th arvo is the next decent window. The swell drops to 5ft from the SW, the wind is a clean cross-off from the SSE, and the energy is 1141. Another one for the experienced crowd at Cunns.
Thursday the 16th morning also looks solid – a 7ft SW swell with a 17-second period and a clean cross-off from the NE. Big, powerful, and clean for the experts.
From the 17th onward, the wind turns onshore and strong, the swell stays small (4ft to 4ft), and it's just messy. A rough end to the run.
The best call? Lock in Wednesday the 8th of July. That 6ft SW groundswell with a 17-second period and clean conditions is the wave to chase. The glassy Thursday the 9th is your backup for a smooth, longboard-style session.
Take care of each other out there,
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.
