Alright, grab a coffee, this is gonna be a tough one. I'm Rusty, and I've looked at the charts for Coxos. Honestly, it's a frustrating outlook. We’re looking at a real dry spell here.
Coxos is a top-shelf reef break, an advanced wave that needs everything to line up. And for the next 16 days, it just doesn't get the right conditions. We start with a bit of hope on Saturday the 4th of July – a 3ft swell from the NNW, which is the sweet spot for this break. The water temp is 66°, pretty normal for this time of year. But the wind is a light cross-onshore, and the wave energy is barely moderate at 219, so it's messy. The period is a short 8 seconds, which is just a windswell making a mess of the lineup.
After that, it turns into a real heartbreaker. From Sunday the 5th right through Tuesday the 8th of July, the swell drops off a cliff and the conditions are poor. There's a long gap here with no surf on offer. We get a tiny pulse of energy on the 10th of July with a 4ft swell, but it's another short-period windswell with a strong onshore breeze. It’s not worth paddling out.
Then things get a bit more interesting, but not in a good way for us. From the 11th of July onwards, we see a big, powerful, and raw groundswell arrive. We're talking 7ft to 8ft waves from the NNW. The combined energy is insane, with readings like 703 and 661 – that is serious power. But it's blowing a fresh breeze, cross-onshore at 22 mph. It’s going to be a lumpy, choppy, dangerous mess. At that size, it’s for experts only anyway, and the wind makes it nearly impossible. Honestly, with that strong wind and that much swell on a reef, this looks way more interesting for kite surfing than paddle surfing.
The second week drags on. The swell stays in the 3ft to 7ft range, but it's relentlessly plagued by lumpy onshore and cross-onshore winds, mostly 12-15 mph. The period is short, and the conditions are just plain poor.
It’s a blank run for the whole forecast period. There isn’t a single standout day. The only glimmer of potential was the 4th of July, but it was marginal even then. Keep your eyes on the charts; things might change, but for now, I'd save the energy for something else.

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.
