The Lowdown
Alright, let’s take a look at what Coxos is serving up for the next couple of weeks.
Honestly, mate, it’s a grim stretch. For a world-class reef break that needs a clean NNW swell, the wind just won’t give us a break. We’re looking at a solid two-week run of onshore and cross-onshore winds, mostly from the north and northwest, which is the one direction that absolutely ruins this spot. The water temp is sitting at 20°, which is pretty average for this time of year, so no surprises there.
There isn’t a single day you’d call a standout. The first ten days are completely dead. From Wednesday the 29th of July through Saturday the 8th of August, every slot is poor quality. The swell is tiny, mostly under 3 feet, with weak energy. The winds are relentless – moderate to fresh breezes from the N and NNW keeping everything choppy and lumpy. You might see a marginally less terrible window on Monday morning the 3rd of August and Tuesday the 4th of August, but with the swell that small and the wind still from the wrong direction, it’s not worth paddling for.
The real energy finally arrives around the second week. On Sunday the 9th of August, the swell hits around 5 feet from the NNW with a big jump in energy. But it’s paired with a fresh cross-onshore breeze and a short, weak period. It’s going to be a mess. The following Monday the 10th of August is the biggest pulse of the entire outlook – swell around 8 feet from the NNW, with a massive surge of energy. That’s a lot of water. But the cross-onshore wind is strong, a solid 25 mph from the north, turning it into a washing machine. This setup looks way more fun for a kite surfer than anyone on a paddle board.
The rest of the week sees the swell drop back, but the wind stays onshore. There’s no window of clean, glassy conditions. Not one.
So the long and short of it is: don’t bother. This is a total blank run for Coxos. Keep an eye on the charts, but right now, there’s nothing to get excited about.

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.
