The Lowdown
Alright folks, Rusty here. We’ve got a 16-day look at Coxos, and I gotta be straight with you – it’s a long, tough wait for anything worthwhile. The pattern is pretty grim for a while, so let's break it down.
Right off the bat, we’re looking at Monday, July 27th, with a small 3 ft swell from the NNW, but it’s onshore and the energy is weak (230). The water temp is sitting at 70°, which is about normal for this time of year. Honestly, it’s a write-off.
Tuesday the 28th sees a little bump to 4 ft, but the wind is still on it, and the energy is just moderate (333). Not the clean conditions we want. By Wednesday and Thursday, the swell drops right off, and we’re stuck with messy, cross-onshore winds. The energy is weak, dipping below 100. This is a real bleak stretch.
We then slide into a gap from Friday, July 31st, all the way through to the end of the first week of August. For a solid week, the guidance is calling it "poor surf conditions" with nothing but onshore and cross-onshore winds. The swell is a mix of small, short-period stuff, and the energy, while sometimes moderate, is just not translating into any quality. The crowd factor at Coxos is "often," but with this quality, it won't matter.
Things start to look a bit more interesting, but not for the right reasons, around Thursday, August 6th. The swell is building, hitting 6 ft and then 8 ft, with strong energy (640). But the wind is a fresh cross-onshore, making it lumpy. By Friday, August 7th, we’re looking at a solid 10 ft swell from the NNW with very strong energy (1309), but the wind is still messing it up. At this size, it’s only for experts, and the conditions are just poor.
The only real standout window comes on Saturday, August 8th. We’ve got a 8 ft swell dropping to 7 ft, and the wind finally goes light, with a period of cross-onshore and then offshore. The energy is still strong (769 and 513), and the swell is from the NNW, which is the optimum direction for this reef. This is the best on offer. It’s still a big swell, so it’s for experienced surfers only, and the tide could be a factor, but it’s the one day with a chance at some clean, powerful waves.
After that, Sunday the 9th through to Tuesday the 11th everything goes to hell again. The swell stays big, 8 ft to 10 ft, with ridiculously strong energy (over 1000), but the wind is a strong cross-onshore, making it total mess. This is more of a kite-surfing setup than a paddle-surfing one.
So, to sum it up: the first week is a total loss. The second week has a massive, windy swell that’s only good for experts on a single day, August 8th, if the wind plays nice. For the rest of the time, you’re better off keeping the board in the car. The forecast can change, but right now, it’s a tough stretch.
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.
