Alright, Rusty here. Let's have a look at what's on the cards for Cunns over the next couple of weeks.

The week ahead is a mixed bag, with the standout period shaping up for Wednesday the 8th, and a real belter looking likely for Monday the 13th of July, though that one's a bit further out.

We kick off on Tuesday the 7th with some promising surf. Tuesday morning we’re seeing a 4ft SW swell, with a 15-second period and a gentle cross-off breeze. Water temp is 61°, which is about average for the time of year. It’s not huge, but it’s clean and has some decent energy behind it. Tuesday afternoon the wind swings offshore and the period stretches to 16 seconds, with swell energy building. It’s a solid start.

Wednesday the 8th is where things really kick off. Morning sees the swell push up to 6ft from the SW, with a 17-second period. The combined energy is strong and the wind is a light cross-off. The comment says this is excellent for experienced surfers, and I can see why. This is the best session of the first week. The afternoon stays similar at 5ft and clean.

Thursday the 9th and Friday the 10th are a write-off. Swell drops, but worse than that, the wind turns cross-onshore and conditions get choppy. We’re looking at poor to marginal surf at best. Saturday the 11th is also poor, with strong onshore winds making a mess of things. Sunday the 12th sees the swell pick up to 7ft, but it’s accompanied by a strong cross-onshore wind and choppy conditions, so it’s not one to get excited about.

Now, hold onto your board, because Monday the 13th of July looks potentially incredible. The afternoon session is the clear standout of the entire forecast. We’re looking at an 12ft SSW groundswell with a 17-second period and a combined energy reading that is extremely strong. The wind is light and cross-shore. That is a huge swell for experienced surfers only. The morning is also decent at 8ft. This is the one to circle on the calendar, but being a week and a half out, treat it as a promising long-range call.

The rest of the second week is a bit of a fade. Tuesday the 14th has some clean surf in the afternoon and Wednesday the 15th sees a return of offshore winds and clean 5ft to 5ft surf. Conditions then deteriorate again from Thursday the 16th through the weekend, with strong onshore winds and increasingly poor wave quality, before a brief improvement on the final day, Tuesday the 21st of July, which has some clean 6ft surf in the afternoon.

Overall, the pick is Wednesday the 8th and the big Monday the 13th. Cunns is an advanced reef break that can be inconsistent, but when it’s on, it’s on. For the first half of the month, the water is about average for the season. Keep an eye on that 13th.

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.
