Updates in hr min s Forecast update imminent
G’day, Rusty here. We’ve got a solid run of surf coming up at Cunns over the next couple of weeks, but it’s a mixed bag of quality and conditions. This is an advanced reef break, so not one for the groms or the timid. It’s inconsistent, so when it’s on, you gotta be ready.
Right off the bat, Saturday morning the 4th of July kicks things off with a clean 6ft swell from the SW, a long 13-second period, and light offshore ESE winds at 9 mph. The combined energy is moderate (917), and it’s glassy and clean. That’s a beauty of a session for the experienced crew.
Saturday afternoon stays clean and offshore, with the swell dropping a touch to 5ft but the period stretching to a lovely 14 seconds. Gentle offshore E winds. Still very good.
Sunday the 5th sees the swell bump up to 6ft with a super long 17-second period (groundswell) from the SW. The wind swings ENE at 12 mph, which is cross-offshore, so it stays clean. The energy jumps to strong (2191). But the report flags it as marginal due to tide. Still, for the experts, that long-period groundswell will wrap nicely into this reef.
Monday the 6th and Tuesday the 7th drop off a bit, with smaller swells around 3ft to 4ft, but those long periods (14-16 seconds) keep the shape good. Winds stay light to gentle and offshore or cross-off most of the time. Good for a sneaky session.
Wednesday the 8th of July looks like a standout. The morning sees 6ft SW swell with an 18-second period – that’s a very long-period groundswell. The energy is strong (1880) and it’s clean with NE cross-off winds. The afternoon gets even better: 5ft, 16-second period, clean, and the report says excellent for experienced surfers. That afternoon session scores a 4 out of 10 internally, so that’s the pick of the week. The water temp is about average for the time of year.
Things go downhill from Thursday the 9th. The wind swings cross-shore and gets onshore by Friday, making the surf choppy and poor. By Saturday the 11th, we’ve got strong onshore winds and a messy, short-period 6ft windswell (7 seconds). That’s junk. Sunday the 12th has bigger 8ft swell but with strong cross-onshore winds, so it’s a choppy mess. Not for paddling.
Then we get a bit of a second wind. Monday the 13th and Tuesday the 14th of July see the swell sitting around 7ft to 8ft, with some cross and cross-off winds. Tuesday afternoon is a gem: 7ft SW swell, 16-second period, light S winds at 6 mph that are cross-off and clean. The report calls it excellent for experienced surfers – that’s another standout.
Wednesday the 15th and Thursday the 16th are clean and consistent, with 4ft to 5ft swells and long periods. Thursday afternoon has a 4-out-of-10 rating and clean offshore SE winds. Great for the advanced crew. Friday the 17th is smaller but still clean.
The weekend of the 18th and 19th of July turns ugly again with strong onshore winds and lumpy conditions. Avoid.
So the true standouts are Wednesday afternoon the 8th of July and Tuesday afternoon the 14th of July. Both have excellent conditions, clean winds, and that long-period groundswell wrapping into the reef. Get on it.
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.
