Alright, let's break it down. We've only got Cunns to talk about, and it’s a real mix over the next couple of weeks. Water temp is about 62°F, which is normal for the season – no surprises there.
The first proper surf window opens Friday the 3rd. It starts a bit rough with a 8ft SW swell, long 15-second period, and cross-shore wind leaving some texture. But the afternoon cleans right up – light cross-off breeze and still a solid 8ft SW groundswell. That’s when the window really opens.
Saturday the 4th is the real standout. Morning and afternoon both have gentle offshore wind from the ESE, clean lines, and a SW swell dropping from about 6ft to 5ft. The period’s 13 to 14 seconds – plenty of push. Energy is moderate. That’s the best bet early on.
Sunday the 5th still has size – 6ft in the morning with a 17-second period – that’s a proper groundswell. Wind’s cross-off from the ENE and NE, so it'll be clean. The report flags marginal tide conditions, so keep an eye on that.
Monday and Tuesday are smaller, around 3ft, but still clean. Not much energy, but fun for a cruisy session.
Wednesday the 8th morning is the next big highlight. Swell jumps to 6ft out of the SW, 17-second period, strong energy, and clean with a gentle cross-off breeze. That’s excellent surf for experienced folks. Mark it.
From Thursday the 9th onward, the wind turns nasty – cross-shore, cross-on, and gusty. The swell hangs around 3 to 4ft but quality tanks. Saturday the 11th is a write-off.
Sunday the 12th is a mess. Strong cross-on wind, and the swell is short-period and lumpy. The afternoon has a massive 8ft SW groundswell with an 18-second period, but the wind is cross-on and choppy. That’s kite-surfing territory.
The next week (Monday the 13th through Thursday) is mostly blown out, with strong winds and rain. There’s a tiny window Thursday the 16th afternoon and Friday the 17th – 2ft or less, clean winds, but very small, long-period swell. Fine for a longboard session if you’re desperate.
Best bets: Saturday the 4th for clean, fun surf all day. Wednesday morning the 8th for the experienced crew looking for some real power.

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.
