The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for your area. I gotta be straight with you – it’s a tough run of luck coming up.
Look, the only spot in the cards is Coxos, a reef break that’s exposed to the swell and needs that NNW direction. But for the next week and a half, the wind is just a killer. We’ve got a solid 16-day window here, but the first surf recommendation doesn’t come until Sunday the 9th of August, and it’s only a marginal shout. After that, there’s a long stretch of poor surf conditions, with the wind almost always cross-onshore or onshore, chopping everything up. From the 7th through the 16th of August, it’s a real grind – the swell is small and the wind is just wrong.
The only real glimmer of hope is a decent pulse of energy that arrives around Monday the 17th of August. The combined swell energy jumps to 864 (moderate wave energy), with the swell hitting 8ft from the NNW. But that’s a big wave – over 8ft, so this is strictly for experts only. The period is a short 8 seconds, so it’s a windswell, which means it’ll be a bit fat and gutless at a reef like Coxos, but the power is there. The problem is the wind is still onshore or cross-onshore, hammering it with a fresh breeze. It’s going to be lumpy, messy, and a real battle. For the average surfer, this setup looks more interesting for kite surfing than paddle surfing.
The water temperature is about average for the time of year, so no surprises there. Crowds at Coxos are ‘often’, so expect company if you’re brave enough to paddle out, but with the wind like this, it might keep a few people off the water.
Bottom line: There’s no standout session here. The 17th and 18th of August have the most size, but the wind ruins it. For the rest of the 16 days, you’re looking at a lot of wind-affected, small, or just plain messy conditions. Hang tight, check the forecasts, and maybe pick up a new hobby for a couple of weeks.
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.
