The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Right off the bat, we've got a pretty grim stretch coming up. For the first seven days, the wind is absolutely howling onshore, and the surf is a mess. It's going to be a rough week of waiting it out. The water temp is a bit colder than normal for this time of year, sitting at 67°F.
The first real chance of anything decent comes around Thursday, the 3rd of September. Early that morning, Coxos is looking at a 6ft swell from the NNW, and the wind is dead calm – glassy conditions. That's a rare treat. The swell energy is moderate (435), and the break is a reef that needs a NNW swell to work right. It's an advanced spot, and it's fairly consistent. Because it's often crowded, expect company. This is the standout window of the whole forecast. The period is short at 8 seconds, so it won't be a bomb set, but that clean, glassy surface will make it rideable.
A few days later, on Wednesday the 9th of September, there's another promising morning. Again, glassy conditions with a 7ft swell from the NNW. This is bigger, so it's strictly for experts. The energy is moderate (360) and the period is a short 7 seconds. It's another window where the lack of wind makes all the difference.
Beyond that, the swell drops off considerably, and the wind goes back to being a nuisance. The last week is mostly small, weak, and choppy. There's a slight nod to the 10th of September, but it's not anything to get excited about.
So, the call is clear: if you want a wave, your best bet is the morning of Thursday the 3rd of September at Coxos. The second hopeful morning is Wednesday the 9th of September. The rest of the 16 days is a write-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.
