Table - best surf conditions forecast for Coxos over the next 16 days.
Rusty here, checking in. Coxos is a classic reef break that really needs a good NNW swell to show its best, but I’m telling you, the next week and a half is looking slim and sloppy. Water’s at 66°, about average for this time of year.
The forecast starts on July 10th, but there’s nothing worth paddling out for the first nine days. Swell is tiny, winds are onshore or cross-onshore out of the NNW and NW, and the wave energy is weak (72). It’s a long dry spell. By the afternoon of the 11th we get a little more energy (143), but it’s still small and choppy. The first real chance to get wet is Sunday the 12th morning – we get a cross-offshore breeze from the SSW and some clean 2ft swell from the NW, period around 9 seconds. It’s surfable, but nothing special. The next days are more of the same: small, wind-affected, not worth the drive.
Then we hit July 19th. The ocean cranks up to 6ft from the NNW, but the period is a short, choppy 7 seconds, and the wind is strong cross-onshore. The wave energy is strong (314), but it’s ugly. This setup looks way more interesting for kite surfers than paddle surfers – lumpy and blown out.
The real windows for Coxos are Monday July 20th morning and Tuesday July 21st morning. Monday morning brings 6ft of NNW swell, a cross-offshore breeze from the south, and clean conditions. Wave energy is moderate-to-strong (286). Tuesday morning has 5ft of NNW swell, a light cross-offshore breeze, and clean lines, with a bit more energy (368). This is your best bet. It’s a little big for beginners (over 5ft) but solid for anyone with some experience. The swell direction is exactly what Coxos needs.
After that, the wind turns back onshore and the swell drops. Another pulse on July 24th and 25th brings 6ft to 7ft of NNW swell, but the period stays short and the wind is on or cross-onshore – big, messy, and blown out. Not worth it.
So to keep it simple: Monday the 20th and Tuesday the 21st are your days. Crowds can be thick at Coxos, but with that clean offshore breeze, it’ll be worth the lineup. Paddle out on the push.
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.
