Alright folks, Rusty here. Let’s have a look at what’s on the cards for Cunns.

We’re kicking off with a clean, shoulder-high wave on Monday afternoon. The swell’s coming from the southwest, a consistent direction for this reef break, and the southeast breeze is holding it right in the offshore pocket. Water temp is sitting at 61°, which is just a touch below what you'd expect for this time of year; nothing wild, just a little fresh. The combined energy is sitting at 390 (moderate), and it feels like a solid, fun afternoon session is on the table.

Tuesday morning is looking even better. The swell holds at just over 3ft from the southwest, but the period steps up to 15 seconds – that’s proper groundswell energy. The wind is light and cross-offshore from the east-northeast. Combined energy jumps to 519 (moderate), and the wave comment says it all. Tuesday afternoon gets even cleaner with the southeast offshore and a 16-second period, bumping that energy up to 635 (moderate). That’s two solid sessions on Tuesday.

Wednesday is where things start to get interesting. The morning sees the swell bump up to 5.6ft with a 17-second period – that’s a very long period groundswell. Combined energy rockets to 1710 (strong). The wind is a moderate cross-offshore from the ENE. This is still clean, but this size and period at a reef break like Cunns will have some serious power. It’s manageable for the experienced crew. Wednesday afternoon, despite a bit of rain around, the swell holds at 5.2ft with a 16-second period, and cross-offshore wind from the north-northeast. The energy is 1245 (strong). The wave comment calls it excellent for experienced surfers – and I’d agree. This is the standout of the first week.

Now, from Thursday morning through the weekend, the wind goes onshore and the quality drops off. The swell sticks around but gets lumpy and choppy, especially by Saturday and Sunday when the wind cranks up. Sunday morning sees the swell hitting 8.2ft with a 14-second period and 3557 energy (very strong), but it’s onshore and messy. That’s a big, blown-out wall – maybe more for the kites than the paddlers.

Into the second week, Monday 13th July brings a 7.5ft swell from the southwest with a 15-second period and 3230 energy (very strong). The wind is cross-shore from the southwest, which leaves it with some cross-chop, but for the crew who know the reef, there will be waves. The following days through to Wednesday 15th show a drop in size but a return to clean conditions. Wednesday morning is a standout in the second week: 4.6ft, 15-second period, glassy conditions with a light southerly breeze. Combined energy is 847 (moderate). That is a small, clean, high-quality window. Thursday 16th morning still holds clean with a cross-offshore northeaster, but the wind picks up.

After that, from Friday 17th right through to the end of the period on Tuesday 21st, it’s all strong winds and poor conditions. The swell sticks around but the wind is just too strong for clean surf. It’s a real shame, because there is some size and energy in the water.

So, the best on offer? The absolute winner is Wednesday afternoon, 8th July. Chest-to-head-high southwest groundswell with a long 16-second period, cross-offshore wind, and strong energy (1245). For the second week, Wednesday morning, 15th July is the clean, glassy window at chest-high with a proper 15-second swell. Mark those in the calendar.

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.
