The Lowdown
Alright, let’s get this out there. The outlook from Coxos is a bit of a rough stretch for the next couple of weeks. We’re looking at a long run of poor conditions, but there is a light at the end of the tunnel.
The next few days are going to be a write-off. We’ve got a persistent cross-onshore wind messing things up, and the swell is just not doing us any favors. The wave energy is weak, with values mostly in the low double digits, and the period is short and crumbly. It’s going to be lumpy and choppy out there, not worth the paddle. The water temp is about average for this time of year, so no surprises there.
We’re looking at a stretch of nothing from the 5th through the 13th. The wind has got a nasty cross-on component to it, and the swell is just not organized. There are some small pulses, but they’re all getting chopped up. The energy is weak, and the period is too short to hold any shape. It’s a bummer because this spot likes a good NNW swell, but the wind is just ruining it.
Then, around the 14th, the swell starts to pick up proper. The energy jumps, and the size bumps up to around 7 feet. But, again, the wind is still cross-onshore and fresh, so it’s going to be a messy, lumpy mess. This is also when the swell gets over 5 feet, so it’s not for beginners, and the short period is going to make it even harder to surf. It’s just a lot of water moving around with no real shape.
The 15th and 16th see the biggest swell of the forecast, hitting 10 feet on Saturday morning. The energy is strong, but the wind is howling at 22 mph from the NNW, right in our face. This is a situation where the setup is looking more interesting for kite surfing than paddle surfing. It’s big, powerful, and completely blown out.
The rest of the second week stays big and cross-onshore, just a lot of whitewater and bump. The energy stays high, but the quality is just not there.
But then, hold on. On the 20th of August, something changes. The wind swings around to the southeast, blowing offshore at a light 6 mph. The swell is still a solid 6 feet from the NNW, with a period of 8 seconds and strong energy. This is the one to circle. This is the standout. The wind will be clean, the waves will have some push, and Coxos, a fairly consistent advanced reef break, will be firing. It’s going to be clean, and that offshore wind is a major positive. This is the one to wait for. It’s a week and a half away, so long-range, but it’s looking very promising.
So, the bottom line is, don’t get your hopes up for the next week and a half. But the 20th is looking like the day. Mark it in the calendar.

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.
