The Lowdown
G’day, Rusty here. So, for Cunns, there’s no surf worth paddling out for right now—but hold tight, because things clean up later.
The first real opportunity hits Monday, August 3rd in the morning. Swell’s 6ft from the SW, 14-second period, with wave energy at 1273 (moderate). Wind’s light out of the south at 3 mph, cross-offshore, and it’s glassy clean. Water temp’s about 60°, right where it should be for this time of year. This is a reef break and it’s inconsistent, so be ready to wait, but conditions are excellent for experienced surfers. The SW direction is exactly what this spot wants. Monday afternoon sees a slight drop as the wind turns cross, but still rideable.
Tuesday, August 4th afternoon has a glassy window—light NE breeze at 3 mph, 4ft SW swell, 15-second period, 652 energy. That’s clean and fun, though on the smaller side.
Thursday, August 6th morning goes glassy again, with a NE breeze at 3 mph, 4ft SW swell, 16-second period, 921 energy. The afternoon bumps up to 5ft, clean under a light S cross-off at 6 mph, energy at 1146. That’s your other real standout—again for experienced surfers.
Then Friday, August 7th gets messy with a strong N breeze at 25 mph and cross-chop. Saturday, August 8th afternoon offers a brief reprieve: glassy under a light NNW breeze, 6ft SW swell, 14-second period, energy at 1402 (moderate-strong). That’s a solid reef session for those who know the break.
The second week gets ugly. Sunday, August 9th and Monday, August 10th bring 10ft-plus swell, but with gale-force onshore winds—blown out, dangerous, and better for kites. Energy hits 5913 on Monday morning, but the wind ruins it. Tuesday through Thursday stays poor with strong winds and lumpy conditions.
Friday, August 15th morning shows a tiny 2ft SW swell with a crazy 23-second period—very long period groundswell. Energy at 1262, but the wind is cross-on NW at 9 mph, and it’s choppy. That period needs a point or reef, but the wind kills it. Saturday, August 15th morning has 6ft SW at 17 seconds, but a fresh N cross-breeze and lumpy chop—not worth it.
The clear winner is Monday morning, August 3rd: clean, solid, and memorable. Thursday afternoon, August 6th is a close second. The rest is a wrestle with the 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.
