The Lowdown

Alright, let’s have a look at what’s coming up for Cunns. This is a reef break, exposed to the SW swell, and it's an advanced spot that’s inconsistent – it doesn’t just fire on every pulse.

Right now, there’s a solid pulse of swell in the water, but it’s messy. Thursday morning the 23rd sees a 7ft SW swell with a 14-second period, and the combined energy is a powerful 1708 (moderate-to-strong). Cloudy skies and a 16 mph cross-off wind from the south keep things clean, but the data flags it as marginal. The water temperature is 61°F, which is about average for the time of year, nothing unusual. This one is for the crew who know the reef well.

Friday morning the 24th is where it starts to look better. We’ve got a 6ft SW swell, period stretching to 15 seconds, and the energy is still strong at 1436. The wind swings SE at just 6 mph, offshore, and it’s classified as clean. The conditions are rated for experienced surfers – this is a genuine standout. Light offshore breeze, solid groundswell, and the reef will be working. If you can get out there, this is the best session of the near-term.

The weekend drops right off. Saturday the 25th and Sunday the 26th are poor – small, weak swells around 4ft, shorter periods, and cross-on winds. Not worth paddling out for. The gap continues through Monday the 27th with onshore winds and tiny surf.

Then we see a glimmer on Tuesday the 28th – the swell bumps back up to 6ft from the WSW, period 14 seconds, energy is 1186, but the wind is a messy cross-on from the SW at 16 mph. The afternoon is lumpy and cross-shore, only marginal. Not a clean day.

Wednesday the 29th is a big jump. A 8ft SW swell, 16-second period, and energy is roaring at 2594 (strong). The wind is cross-off from the SSE at 12 mph, keeping it clean. This is a powerful, long-period groundswell – perfect for the reef, but this size is for experts only. The data says it’s still marginal, but this is the kind of day that gets the adrenaline going.

Thursday the 30th is a notable drop-back. A 5ft SW swell, 13-second period, with light ENE cross-off winds and clean conditions. The energy is 734, moderate. The data says "expect very good surf conditions," and it’s a solid all-rounder for the more experienced.

Now, looking ahead to the first week of August, keep an eye on Saturday the 1st of August. The afternoon session brings a 5ft SW swell, 18-second period, with light SSE cross-off winds and clean conditions. The energy is 1261, and it’s rated excellent for experienced surfers. That’s a standout in the second week.

Sunday the 2nd of August afternoon is glassy – a 4ft SW swell, 16-second period, with zero wind and glassy conditions. The energy is 1234. That’s a very rare, perfectly clean session for a reef break, though you’ll want to be on your game.

Wednesday the 5th of August morning is another highlight: a 6ft SW swell, 18-second period, with light E cross-off winds, energy at 1729, and rated excellent for experienced surfers. Clean, lined-up, and punching.

Overall, the best of the near-term is Friday morning the 24th of July, hands down. For the second week, the standout is the afternoon of Saturday the 1st of August, with the glassy Sunday the 2nd a very close second.

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.
