The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Coxos.
Honestly, I’ve got to call a spade a spade here. Looking at this 16-day stretch, it’s a tough one. We’re looking at a solid run of poor conditions right from the start. For the first week, from Friday the 31st of July right through to the 7th of August, there’s nothing worth paddling out for. The wind is a constant problem, mostly cross-onshore or onshore from the NNW, sitting at 12 to 16 mph. Swell is tiny, barely scraping 2 to 3 feet, and what’s there is messy. The wave energy is weak to moderate at best. It’s a write-off. Coxos, being an exposed reef break, needs some love, and it’s just not getting it.
We do see a little bump in size around the 8th of August, with swell hitting 4 ft from the WNW and energy climbing to a moderate level. But that onshore wind from the NNW at 12-16 mph is still spoiling it, making for choppy, lumpy conditions. You’d be fighting the wind more than the wave. The morning of the 10th of August pushes up to a solid 7 ft from the NNW with strong energy, but again, the cross-onshore wind is just too much. That's expert-level size with poor quality wind; it would be a washing machine out there, and more of a kite-surfing proposition than a paddle session.
The best chance of something decent actually comes a bit later. On the morning of Tuesday the 11th of August, the swell drops to a cleaner 3 ft from the west with a 10-second period and strong energy. The wind is still cross-onshore from the NNW at 9 mph, but it’s lighter, which might just take the worst of the chop off. It’s still marginal, but it’s the only window that gets a sniff of a recommendation. The west swell direction isn't the optimum NNW for Coxos, but it’s the cleanest wind we see all period.
After that, we go back into a pattern of fresh cross-onshore winds and moderate to strong energy but poor quality, lasting right through to the 15th of August. The water temp at the start is about average for the time of year at 68°.
Look, it’s a bleak outlook. There’s no stand-out day here. If you’re desperate, keep an eye on the morning of the 11th of August for a possible, albeit messy, session.
Rusty, signing off.

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.
