Table - best surf conditions forecast for Cunns over the next 16 days.
Alright, Rusty here. Let’s break down the next 16 days for Cunns.
We’ve got a dead start. Nothing worth paddling for until Tuesday the 14th of July. There’s a couple of days of flat or junk surf before that, so don’t bother waxing up yet.
The real window is that mid-week push. The pick of the forecast is Tuesday afternoon, the 14th of July. You’ve got a 7ft SW groundswell with a very long 16-second period, and the wind is light from the south at 15 km/h, blowing cross-offshore. That’s clean. That’s the kind of glassy, lined-up reef surf you wait for. The wave energy is strong (2389), so it’s got plenty of punch. Water temp is 61°, which is just a hair under the seasonal average, so nothing crazy. It’s a spot that’s inconsistent, so you’ll need to be patient, but the sets that come through will be well worth the wait. This size is for experienced surfers only.
Wednesday the 15th of July keeps the quality going. Both morning and afternoon have a light cross-offshore breeze from the ENE at 15 km/h. The swell drops to 5ft, but that long-period SW energy is still there. The energy is moderate (1138), making it a little more manageable, but still with good shape.
After that, it starts to fall apart. Thursday the 16th has a brief window, but the wind is cross-shore and the wave quality is marginal. From Friday the 17th all the way through the 28th, it’s mostly blown out or too small. There’s a pulse of size on the 24th with a 2.5m (8ft) swell, but the wind is onshore, so it’s messy. The 27th has some 2m+ (7ft+) swell, but again, the wind is fighting it.
So, the honest truth is, you’ve got one solid window: Tuesday afternoon and Wednesday the 14th and 15th of July. That’s where the quality is. The rest is a long stretch of poor conditions. Don’t hold your breath for the second week.
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.
