Alright, folks. Rusty here. Let’s break down what’s in store for Cunns.
It starts off strong. On Friday, July 3rd, we’ve got a proper swell pushing 8ft out of the SW with a 15-second period. That’s some real groundswell energy, and the combined power reading is 2928 (strong). Winds go light and offshore in the afternoon, making for a clean, powerful wave. This is the standout window for experienced surfers only.
Saturday the 4th is a bit smaller, 5ft to 5ft, but still with offshore winds. Clean and manageable.
Swell drops under 4ft for Monday and Tuesday, but here’s the gem: glassy conditions. Zero wind. Tiny but perfect.
Wednesday morning the 8th of July is the other major highlight. Dead calm winds, a solid 6ft SW swell with a 17-second period, and combined energy of 1886. It’ll be clean, lined up, and a real treat for those who know the reef.
After that, a mess of onshore winds and slop sets in through the weekend, with some rain and gusty conditions. Steer clear.
The following week brings heavy water. Monday the 13th up to Thursday the 16th sees waves hitting 10ft, with periods over 18 seconds and combined energy up to 4541 (very strong). That’s big, but onshore winds spoil it until Wednesday the 15th.
Wednesday the 15th of July is the final standout. Offshore winds from the SE meet a clean 8ft SW groundswell with a 16-second period, energy at 3492. Expert-only territory, but it’s going to be epic.
We finish with a glassy Thursday afternoon, 5ft, clean.
Remember, Cunns is an *inconsistent* reef break that only works when the conditions line up, and it gets crowded sometimes. Best bets: Friday afternoon the 3rd and Wednesday morning the 8th of July.
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.
