Table - best surf conditions forecast for Cunns over the next 16 days.
The Lowdown
Alright, let’s get into it. Cunns is the only spot we’ve got on the radar for this stretch, and honestly, it’s a mixed bag. The water temperature is running about 60°, which is pretty average for the time of year – nothing to write home about, but you won’t be needing a thick suit.
The first few days don’t offer much to get excited about. Saturday afternoon the 1st is a write-off – cross-on wind, choppy, and just messy. Sunday the 2nd is a little better with a 5ft SW swell and a 15-second period, but the cross-shore wind keeps things bumpy. Not worth paddling out for.
The real standout window is Monday the 3rd of August. The morning session is where it’s at. You’ve got a solid 6ft SW swell with a 14-second period, light SSE cross-off breeze, and the guidance says clean conditions. The combined energy is moderate (1273), and this is the best quality on offer for experienced surfers. The reef setup at Cunns should handle this well, but remember it’s an inconsistent break and tends to be for advanced crew only. Crowds are possible here, so keep an eye out.
After Monday, things drop off again. Tuesday the 4th has a glassy morning with a small 4ft SW swell, but it’s weak energy (505). The afternoon glass-off is even smaller at 3ft. Thursday the 6th could be a fun little window – glassy morning, 4ft SW swell, very clean, but the swell is small. The Thursday afternoon session is cleaner still with a 4ft SW swell and offshore wind, but again, nothing huge.
From the 7th onwards, it gets wild. Strong winds, big swell, but poor conditions. The 9th to the 12th sees swell over 8ft and even up to 12ft, but the wind is onshore or cross-on, making it a messy, stormy mess. That’s kite-surfing territory, not for paddling. By the 15th and 16th, the swell drops back but the wind is still onshore, so no real clean options.
Bottom line: the best bet is Monday morning the 3rd of August at Cunns. That’s your window. Everything else is a gamble or a washout.

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.
