The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for our region.
Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. There’s a long stretch ahead with very little to get excited about. From the start of the forecast through to the 18th of August, the conditions are mostly blown out with cross-onshore winds and that swell is just not cooperating. The waves are small and weak, with combined energy values sitting mostly in the low two-digit and three-digit range (like 264, 270, 260), which just isn’t enough to hold any shape. That NNW wind is a constant problem. You’re looking at a lot of choppy, lumpy, and poor quality surf.
The first real glimmer of anything half-decent doesn’t show up until Wednesday, 19th August. Even then, it’s only a “marginal” call. The swell pushes up to 7 ft from the NNW, with a period of 9 seconds, and the combined energy jumps to a strong 734. That’s some serious power in the water. But here’s the kicker – the wind is still cross-onshore, and the report says “light cross-onshore with small wind ripples.” It’s not clean. For a reef break like Coxos, that’s a tough one. The NNW direction is right on the optimum swell direction for this spot, so the potential is there for wedgy, powerful lines, but the wind is going to mess with the surface. The swell is over 7 ft, so this is for experienced surfers only – this is expert territory. The water temperature is about average for this time of year, nothing unusual.
If you’re desperate, the 19th of August is the closest thing to a standout, but it’s a promise with a catch. The wind just isn’t right. It’s a long wait for a maybe.
Before that, the 18th of August sees some solid swell (8 ft) from the NW with a strong 802 combined energy, but again, the wind is cross-onshore at 25 km/h. It’s a kite-surfing setup, not a paddle-surfing one.
In short, keep your board in the bag for a while. The 19th of August is your best shot, but don’t get your hopes too high. The rest of the two weeks is a write-off.
Rusty.

Information about the Coxos Surf forecast
The above surf forecast table for Coxos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coxos can be found by selecting the local surf guide option on the grey menu. Our Coxos 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 (Coxos) 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 Coxos 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.
