The Lowdown
Alright, let’s break it down. The only wave in the picture is a reef break that’s a tricky one, only for the experienced crew. It’s inconsistent, so you’ll be waiting your turn. Over the next two weeks, it’s a real rollercoaster, but there are a few sweet spots.
The first few days are a total loss. Friday the 17th and Saturday the 18th are a mess of cross-shore wind and chop. There’s a 4ft SW groundswell with a long 16-second period, but the wind is all wrong. Sunday and Monday morning are the same story – poor.
Then, Monday afternoon the 20th, the wind drops to glassy. It’s a clean 3ft SW swell. The energy is moderate (420), but the glassy conditions make it a real treat.
That’s short-lived. Tuesday and Wednesday are back to poor, with a fresh cross-onshore wind ruining the 4ft to 5ft swell. By Thursday the 23rd, the swell jumps to 7ft, and the wind turns clean cross-offshore. The energy is strong (1760), but it’s a big one for the reef. The morning of the 23rd is a standout for the pros.
The real glory starts on Friday the 24th. The wind goes offshore, and you’ve got a 5ft SW swell. The energy is strong (1048), and it’s clean. The afternoon of the 24th is one of the best calls of the forecast. Saturday the 25th is also a winner, with a 5ft swell and a light offshore breeze.
Looking further ahead, the end of July and start of August has a few more gems. Monday the 27th has a 5ft SW swell with a very long 17-second period, clean offshore wind, and strong energy (1154). Tuesday the 28th has a 7ft swell, big and powerful. The 31st of July, Friday morning, looks magic: 5ft SW swell, 16-second period, and a slight offshore breeze. That’s another top call.
So, to sum it up: the first few days are a washout. The two absolute standouts are the afternoon of Friday the 24th and the morning of Friday the 31st. Both have clean offshore wind, a good SW groundswell, and are for the advanced crew only. The water temperature is about average for this time of year. This reef can get crowded when it’s good, so expect some company.

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.
