The Lowdown
Hey, Rusty here. Looking at the next 16 days at Cunns, and there’s some proper swell coming through.
First real surf is Thursday the 23rd of July, but it’s average – 6ft swell from the SW with a long 14-second period, but that 25 km/h southerly is cross-off and messy. The wave energy is pumping at 1570, but it’s not clean enough to get excited. Thursday afternoon is similar.
Friday the 24th is where it fires. Morning has 6ft SW swell, 15-second period, and a light 5 km/h ESE offshore. That’s clean, strong energy (1314), and excellent conditions for experienced surfers. This is a standout. The afternoon holds up too – same size, glassy feel.
Saturday the 25th drops to 4ft SW swell, 13-second period, and absolute glass in the morning (0 km/h wind). The energy is moderate at 437, and it’s clean, but the size is small. Fun for a longboard, but not a standout.
Sunday the 26th turns ugly – onshore winds and choppy. Monday the 27th is similar.
Tuesday the 28th fires again. Morning has 6ft SW, 15 seconds, but light onshore wind. The afternoon though: 7ft SW swell, 15 seconds, and a 10 km/h southerly cross-off. Clean waves with massive energy (1832). This is the other standout. Wednesday the 29th keeps it going with 6ft to 6ft SW, long period, and clean offshore.
Thursday the 30th backs to 5ft, still clean. Friday the 31st drops to 2ft – small but clean.
Into August, Saturday the 1st morning is glassy with 4ft SW swell and a 16-second period – very long groundswell, perfect for the reef. Sunday the 2nd holds 5ft, but cross-shore wind messes it. Monday the 3rd is blown out by 35 km/h winds.
Wednesday the 5th of August is a sneaky late one. Morning is small (2ft) but with a 19-second period – very long groundswell and light wind. Afternoon gives 3ft SW, 18 seconds, and a clean cross-off. Thursday the 6th keeps 4ft SW with 16 seconds, but wind is variable. Friday the 7th is wrecked by 40 km/h northerly.
Water temp is about average for this time of year at Cunns, so your usual wetsuit will do.
Best on offer: Friday the 24th and Tuesday the 28th – solid SW swell, long period, and clean offshore wind. Crowds are “sometimes,” so you might see a few, but it’s a reef so there’s waves for everyone.
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.
