The Lowdown
Alright folks, Rusty here. Gonna level with you—this outlook for Coxos is rough. A real stretch of flatness followed by a whole lot of messy, blown-out energy.
Right now, through the first week, it’s dead. The water’s sitting about average for the time of year at 69°, but you wouldn’t be in it for the waves. From Friday the 7th all the way through to Thursday the 14th, it’s a total bust. Day after day of poor conditions, mostly a moderate cross-onshore wind out of the NNW keeping things choppy. The swell is tiny, mostly under 3ft, with weak energy in the 160 to 358 range. It’s a blank stretch—nothing to ride.
The only flicker of life shows up on Saturday the 15th. Swell jumps to about 5ft from the NNW, with the combined energy hitting a proper 464—moderate to strong. But here’s the kicker: it’s only considered "marginal." The wind is a light cross-onshore from the north, not clean. For this spot to sing, you’d want that offshore SE breeze. The period is only 8 seconds, so it’s short-period wind swell, not those long lines this reef loves. A small window, but if you’re jonesing, it’s the best look for the next two weeks.
Sunday the 16th offers similar: 5ft from the NNW, still that light cross-onshore, and a "questionable" tide. Nothing to write home about.
Then it gets ugly. From the 20th through the 22nd, we see wild numbers—energy readings like 522 (strong), 1238 (very strong), and 885. Swell size hits 10ft on the 21st, but it’s paired with a fresh, onshore wind gusting 30 km/h. The period stays short at 8-9 seconds. For a wave this powerful with that much lumpy wind, this beach-and-reef setup looks more like a kite surfer’s dream than a paddle surfer’s session. That 10ft+ is way too big for most, and the wind will chop it to pieces.
Best bet? If you need to get wet, the only standout is the morning of Saturday the 15th. It’s the first real swell of size with the lightest wind. It’s not quality, but it’s the only game in town.
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.
