Alright, let's break it down in feet and degrees for the crew that thinks in imperial.
So, here's the deal for Cunns. It’s a reef break, so it doesn't work all the time, but when it does, it’s a gem. The water is sitting at 61°F, which is pretty standard for this time of year, so no major surprises there.
The calendar starts quiet, with the first real action on the 4th of July. Saturday morning is looking sweet: a 6ft SW swell with a 13-second period – plenty of travel time on that energy. The wind is a light offshore from the east, so the face will be clean. The power reading is 917, which is a solid, fun amount of energy. Not too heavy, not too weak. Saturday afternoon stays similar, just easing back to around 5ft with that clean offshore wind holding.
Come Sunday the 5th, the swell bumps up to 6ft with a 17-second period. This is a serious, drawn-out groundswell. The energy jumps to 2191, so you can feel that weight. The wind switches to a moderate cross-off out of the ENE, which keeps it rideable but not as perfectly glassy as the day before. That size and period is going to be too much for beginners.
The wind gets a bit more tricky through the middle of the week, with more onshore and cross-shore breezes taking the shine off the smaller 3-4ft waves, but there are still some rideable ones in there if you pick your tide.
For the big-wave hunters, the 14th of July is the date to circle. Tuesday morning serves up a powerful 8ft SW swell with a 16-second period. The combined energy is a massive 2765 – that's some serious ocean power. The wind is a moderate cross-off from the south, so it should be clean on the face. This is strictly for the expert crew; 8ft on a reef with that kind of period is not the place to learn. Tuesday afternoon is still solid at 7ft with the same clean conditions.
The standout pick: For the best all-round, get-in-the-water session, I'm calling Saturday the 4th. That morning session at Cunns with 6ft of clean, long-period SW swell and light offshore wind is as good as it gets for a fun, quality session. It's got push, it's clean, and it's not trying to kill you. Just keep an eye out for the local crew because Cunns can get 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.
