The Lowdown
Alright, mates, Rusty here. Gotta be honest with you—this 16-day forecast for Coxos is a tough pill to swallow. There’s swell on the way, but the wind is going to be the boss, and it’s not playing nice.
The first few days are total write-offs. Onshore and cross-onshore winds, choppy surf, and tiny waves. We’re talking under 3 feet and weak energy. Monday the 3rd might give you a fleeting bit of clean surf with a light offshore wind, but it’s barely 2 feet with almost no push. Not worth the wet suit.
From the 4th through the 7th, it's more of the same. Small, weak, and blown out. The wind just doesn't let up.
We finally get some real size on the 8th and 9th, with waves building to head-high and beyond (5-6 feet). The energy is picking up into a moderate range. But again, that wind is cross-onshore, so it’s lumpy and messy. Not the clean reef we know and love.
The 14th and 15th are the big days, size-wise. We’re talking 6-7 feet of northwest swell. That’s proper, powerful stuff. The energy readings are strong—well over 700 on the 15th. But the wind is screaming from the north at 25 mph. It's going to be a full-on mess. At this size and with that wind, this is less about surfing and more about survival. I’d say that setup looks way more interesting for kite surfing than for a paddle session.
The 16th is still a solid 6 feet, but the wind backs off a bit, though it's still cross-onshore. A little better, but still not clean.
The bottom line? There’s no standout day in this whole period. The waves will come, but the wind will ruin most of them. That Monday the 3rd is the only shot at clean glass, but it's tiny. The big swells are all blown to pieces. It’s a rough outlook for a spot that deserves so much better.
Rusty out.

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.
