The Lowdown
Listen up, crew. Rusty here, giving you the lowdown on Coxos for the next couple of weeks. It's a game of patience, that's for sure. This reef is a gem, but it's going to take some waiting for the wind to play nice. The water's at 20°, right where it should be for this time of year.
The first week is a tough one. From Saturday the 5th all the way through to Saturday the 12th, the wind is blowing like crazy. It's a constant cross-onshore, sometimes straight onshore, at 15 to 22 mph. It's just going to turn everything into a mess. There's some proper size in the swell, like on Sunday the 6th morning with a 12-second groundswell, but the wind will wreck it. It's a total write-off for paddle surfing. Honestly, with that much wind, this looks like a kiteboarding spot for the week.
But hold on, there's a light at the end of the tunnel. The real standout is Tuesday the 15th. The morning brings a clean 7ft swell from the NNW with a light cross-shore breeze from the NE at only 6 mph. The wave energy is pumping at 793. By the afternoon, the wind is a light cross-onshore from the W at 6 mph, with the swell holding at 7ft and the energy jumping to 1025. This is the one to aim for. It's a big swell, but on a quality reef with that light wind, it's going to be a blast. Coxos can get crowded "often," so get there early.
Wednesday the 16th is another top pick. The morning is looking unreal with an 8ft NNW swell and a near-perfect glassy NNW wind at just 3 mph. The combined energy is a massive 1524, and this is the kind of day that makes you remember why you surf. The afternoon wind picks up a bit, but it's still very clean. This is a big wave, though. Over 8ft, this is for experts only. The swell period is a bit shorter at 8-9 seconds, so it'll be a bit more sectiony, but the conditions will be impeccable.
After that, the wind builds again through the rest of the week. We get a final chance on Saturday the 19th morning with a small 3ft WNW swell and a clean, light cross-offshore breeze from the ESE. It's not going to be big, with the energy at 199, but it'll be a clean, fun session for a log. Sunday the 20th morning is even smaller but glassy clean with a light offshore from the SE. A small, clean end to the run.
Signing off, 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.
